I designed a EGR defeat circuit that has been discussed in other threads. Combined with an EGR blocker plate, the circuit fools the ECM that the EGR is still working. The circuit is very simple. I have been running my truck with a prototype for about a week now and have no codes and the EGR is fully blocked. I have sent another prototype to a Calafornia LLY owner to see if he gets good results.

I wanted a nice small package for the defeat circuit, so I commisioned some PCB's to be made, but they had a minimum order. I want one for myself, and maybe another for a friend. That leaves 22 potential circuits available. Is there any interest?

This is a pic of one half made.

As you can see, they are very small. Here is the Schematic if you want to build your own.

Fingers,


You didn't mention a price. . .


Dennis

yeah im in for one......

Count me in

I'm in.

Fingers, did you get access to the plugs for the MAF or do you have to splice into the wires?

I'm in, let me know price

Fingers I want one as well.


Greg

I would like to recover the cost of developing these, as well as parts. I don't expect a huge demand. How does $15 Postage included sound?

I looked into getting the plugs. I know they are Delphi GT Keyed plugs, but I don't have a supplier. If someone can point me at a supplier, I would be happy to wire them up. As is, you will have to patch these into the wires yourself. That is what I did and it wasn't a big deal, but everyone is different.

Oh, BTW, I will not be making these for others till I have had a chance to run one of the "production" sticks on my truck and get a warm fuzzy.http://www.dieselplace.com/forum/smileys/Big Smile.gif

Finally, a disclaimer. Though I have not had any problems, I can not be responsable for any problems you might have from the use of this circuit. It is provided "as is".

Fingers, when you are able to get your hands on the plugs I am in for one. I dont really want to tap into wires if I dont need to.

Yes, plugs would be good!


How about a "package" consisting of the block plate and the electronics?

$15 sounds like a bargain. I'll take one.

Fingers,


For connectors try http://www.waytekwire.com/


I want one.


Allie

Wish I could get the plugs. If and when I do, I'll wire them. Till then, this is all I have, sorry. Here is a pic of what the final package will look like. Someone could help me out there and find a resource for the plugs.

http://www.dieselplace.com/forum/uploads/Picture_013.jpg

I will be running this one next week on my truck to make sure the design is still good.

I am in for one and still need to get a blocker plate. Let me know the info if you still have any left

I like the blocker plate and circuit combo.........yeah???

Yep,


That's what I was thinking. Make it into a one-stop-shop for the whole EGR mod. I am sure us CA and other non-fed rules guys will be most appreciative! http://www.dieselplace.com/forum/smileys/Big Smile.gif


How water/dust/heat proof will the housing be for the electronics?


We should call this the FINGER mod since those wires sticking out look like fingers on a mishappen hand :)Edited by: hamsalad

Would love to get the combo. Thanks for your work on this!! Mark

Reliver is actually the plate guy. I just facilitated the transactions with Paypal. I guess we will have to talk.

I have ReyChem on order to seal this thing up tight.So water/dust shouldn't be a problem.

Thought you might get a kick out of the B side.

http://www.dieselplace.com/forum/uploads/B8Z_mvc-578f.jpg

I would be interested in one. Just want to see how it does on the cali trucks first.

Fingers,


That's a cool lookin board with the custom sig on it. So, when we want one of these we just say, "Give me the FINGER" http://www.dieselplace.com/forum/smileys/Big Smile.gif


So, what did you think about a combo deal with the plate and 'tronics?

Max mod


with a


Finger fix





http://www.dieselplace.com/forum/smileys/HiHi.gif

Fingers;


Sounds like you still get codes and/or error codes with the plate only. If so I would like to get on the list for a circuit board. As with everyone else on this thread we thank you for your time and energy on this project.


Ga. Dmax

With a plug, and sold with the blocker plate would make a really good package. I 'll definitely buy one.

Fingers,


For connectors try http://www.waytekwire.com/

Allie

I see they carry some of the Delphi connectors. I will put together an inquiry and send it off to them.

Thanks

I'll take one.


Do you want me to paypal you?


Thanks,

Hey Fingers, here is another site that carries more of the delphi connectors. www.raffenday.com/products/connectors1.htm (http://www.raffenday.com/products/connectors1.htm)


i am also intrested in one of these finger boards if we can get the connectors to make them workhttp://www.dieselplace.com/forum/smileys/Thumbs Up.gif


JLewhttp://www.dieselplace.com/forum/smileys/Hug.gif

Shipping from the UK would be a little steep.....

Fingers, I saw a post of yours indicating you thought the circut should work on an LB7 w/ CA emissions running on a vacuum but you needed signal ranges from the vacuum sensor. I'd like to try one of these circuts and if you still need the ranges send me a pm with what you need and how to measure and I'll see what I can do. As long as it's got plugs and isn't a perminant install (i.e. I can still remove it and get worranty service) I'm in. I already have the blocker plate (not yet installed).

Fingers, I realized the location afterwardhttp://www.dieselplace.com/forum/smileys/Confused.gif, but I'll keep looking


JLew

On the LB7 with EGR, there is a EGR vacume sensor instead of a EGR position sensor. I don't have a lot of info on the actual sensor, but it should be located in the vacume line between the EGR valve and the EGR solonoid valve. I am fairly sure the operating range on this sensor is different than the EGR position sensor, but I don't know.

I need to know the voltage coming out of this sensor when the solonoid is closed (no vacume) and when the EGR test is in progress. I can scale the signals on the circuit then to do the right thing.

Fingers, here something that might work??

Jim

Values are 330 K/ 1 Meg and 100 K/ 120 K and the op-amp is a lm258 which give the larger operating temps.

sent you money thanks in advance ses light is driving me nuts. I have an 05 with turbo back and it sets egr codes like crazy thanks again John

John K,

If you could, before you install the plate you ordered, could you just install the circuit? All indications are that it will kill the light for those who changed the exhaust, but it would be nice to have confirmation.

Fingers

Hay I'm In where do I send the money. I need the plate and the board. I have a 05 Calif. truck with turbo back exhaust and it set 7 codes http://www.dieselplace.com/forum/smileys/Cry.gif. It also put the truck in limp home mode a couple of times. Its a bunch of egr codes so maybe this will fix my problem. Where do I send the money. Help me pleasehttp://www.dieselplace.com/forum/smileys/Big Smile.gif.

Rotax, I'm only using Paypal right now. Easier for me. See my previous post.

Ok fingers I sent you the 22. I need the plate also thanks. I hope it fixes my problem. http://www.dieselplace.com/forum/smileys/Big Smile.gif My wife is not happy my new truck is screwed up from my exhaust.

Fingers -

Sending you $15 via PayPal.

Thanks

Fingers will do thanks again I will let u know the results John K

On the LB7 with EGR, there is a EGR vacume sensor instead of a EGR position sensor. I don't have a lot of info on the actual sensor, but it should be located in the vacume line between the EGR valve and the EGR solonoid valve. I am fairly sure the operating range on this sensor is different than the EGR position sensor, but I don't know.

I need to know the voltage coming out of this sensor when the solonoid is closed (no vacume) and when the EGR test is in progress. I can scale the signals on the circuit then to do the right thing.


Ok, I did a bit of poking around under the hood and found some discrepencies between the SI and what's under my hood.


First, the SI doesn't show a pinout for the connector to the vacuum sensor, however the schematic does show a 3-pin connection with ORN/BLK and GRY going to/from the boost sensor, and a BRN wire going to the ECM. Well, mine has the ORN/BLK and GRY but the thrid lead is LT GRN. I'm assume that the LT GRN is the sensor circut connection to the ECM.


Second, the circut description for servicing the vacuum sensor says there's a low voltage reference and a 5v reference line. I didn't see either of these (would have expected to see them on the same connector?). I'm pretty sure I'm looking at the right component--there's a vacuum line attached to the bottom of the component (same size tubing as is connected to the egr valve).


Finally, the diagnostic steps refer to testing the 5v reference circut for a short to ground as well as a test for the sensor signal circut, but again there's that pesky question about where these circuts are if they're not on the connector.


Here's a pic of what I'm looking at (the vacuum line is underneath out of site)


http://www.dieselplace.com/forum/uploads/F6B_egrsensor.jpg


So I guess I need to know what to do next? The question seems to be how to measure the signal coming off the LT GRN wire to the ECM during idle and then during an egr flow test, which btw I couldn't specifically find an 'egr flow test' in the SI so I assume that measuring the difference between a connected vacuum system and a disconnected vacuum system would be the equivalent. As an aside, the SI indicates that the egr vacuum control solenoid and vacuum vent solenoid are both normally closed, which keeps the egr valve closed.

Your on the right track.

The Brown or Light Green is the signal. The gray is the ground and the Orange/black is the +5 volt.

To get the readings, I used a sewing pin stuck either into the wire or into the connector where the wire goes in. Take the readings from the Light Green to Ground.

The EGR test phase does not happen till the engine gets up to temp. So you can get the steady state reading while it is warming up. The test will show as a very high reading for several sec, then back to some lower number if it passes.

11 circuits left.

will this work on an o5 cal truck if yes how does paypal work


thanks rob

Fingers, If you sell all of these out are you going to have some more made at a later time?? I am curious to see what luck the Cal trucks do with this fix.





thanx,


JLewhttp://www.dieselplace.com/forum/smileys/Clap.gif

got it. (nice trick using the sewing needleshttp://www.dieselplace.com/forum/smileys/HiHi.gif) The truck's already warmmed up for today so I'll have to wait till later or tomorrow for the test.

I expect the demand for these to be about the same as for the plates. Minus the fact that they need to be hard wired at this time. So my guess is there will be little demand after this batch is sold. So far orders are tracking fairly well to these assumptions.

My feeling for this is that unless I can find the connectors I need to make it a plug-in installation, there will not be enough demand to do another run. I could be wrong. I know the california boys are in a hard way for something like this. Still, the minimum is 24 and there isn't a price break till 100 or so.

To answer your question. Once these are sold, I would need at least 12 more orders before I would do another run.

There have been several questions about the '05's. I honestly don't know if they are the same. However, knowing GM, things should not have changed much if at al. Post a pic of the EGR and MAf connectors for me and I'll tell you if at least they are the same. My SI manual does not cover 05

Better yet, buy me a '05 and I'll do some testing. http://www.dieselplace.com/forum/smileys/Wink.gif

Just sent ya $22 for the plate and Finger Stick!

Six Finger sticks left.

I'll be in for the circuit with connectors and the plate once it will be determined that they will work on and '05. I will try to follow along but let me know if you find connectors that will plug in and out easily. Thanks.

Fingers;


Is this circuit board applicable to the CA, NE versions only or do we need one for Fed also ? Been following this thread as well as the EGR disc. and getting confused what the final set up should be. Can you shed some light ?


Thanks;

I have done all of my testing on my 2004.5 LLY with fed emmisions. I have the plate installed with the EGR plugged in and the Finger Stick wired up. No lights, no codes.

I have sent a prototype out to a california LLY owner for testing. I hope to hear from him soon. All indications are that it will work for CA LLYs too. Just waiting for the final proof.


Four Finger Sticks left.Edited by: Fingers

Ok, here's the numbers I got this morning from the vacuum sensor ('03 CA vacuum system) measured between the LT GRN and GRY leads:


Off: 0.0v


ignition on, engine off: 4.14v


engine on (cold): 4.14v


After about 15 minutes of warmup, the voltage jumped to 4.22v with 2 spikes to 4.28v and one dip to 4.18v, but for the most part it was steady at 4.22v. I left it running for about 10 minutes after that to see if the voltage went down, but it stayed up at 4.22v.

Wanted Lt Green to GROUND (engine block) partner, not the same as the gray wire. Sorry if I wasn't clear enough.

Opps! http://www.dieselplace.com/forum/smileys/Embarrased.gif I'll do another test tomorrow morning. Edited by: donmiller714

No problem, I did the same thing when I was poking around.

Will your circuit work on LB7 CA emissions trucks? Reading the post it seems the focus is on LLY; so I'm not sure if your circuit would work for me.

Good job fingers! My payment has been sent.

2 Sticks left.

Yuck. What we need is someone who makes knock-off replicas for 1/10th the price. Anybody want to start a business?


Dennis

I'm still hoping to get one made with connectors.

Knock yourself out Dennis. I've already posted the schematic. Need a PCB layout?http://www.dieselplace.com/forum/smileys/Wink.gif Materials, with some shopping and volume can be gotten down to about $5 a stick. Takes about 15 min a stick to assemble and test. Considering the time and materials I've put into these, I'm almost working for free.

The connectors are a problem with solutions, but expensive solutions. They would add at least $20 to the price.http://www.dieselplace.com/forum/smileys/Cry.gif Low volume would push it up to more like $35 a set or more.

Heck, the last thing I need is to start my own business. . . Can't keep up with half my hobbies as it is. . . http://www.dieselplace.com/forum/smileys/HiHi.gif I still have parts I haven't had time to install on the truck yet. . .


Dennis

Hope you make a second run with the connectors, I already bought a blocker plate from Reliver but didn't install it yet. Waited to see if worked with out codes. I would definitly would buy one of these with connectors. hope to see more on this soon http://www.dieselplace.com/forum/smileys/Thumbs Up.gif


By the way AWESOME work fingers http://www.dieselplace.com/forum/smileys/Clap.gifEdited by: BlueCrew 04 D/A SB GMC

How many left? I would love to get one.

Still <font color="red">ONE</font> stick available.Edited by: Fingers

I dont care how much it costs to get one with connectors. Heck I'll shoot ya over a hundred if I can get one made up from ya.

I sent $22. Hopefully you still have the ONE left.

Last one sold. All current sticks are now assigned. I expect to ship the circuits Thursday. Ran out of wire of all things.http://www.dieselplace.com/forum/smileys/smiley9.gif

I am waiting for a supply of plates for those that ordered the combo. Question: Do you think I should wait for the Plate and ship them together for those that ordered the combo?? The circuit is useless without a plate.

There will not be another run till some of this batch gets installed and there is feedback from someone besides me. http://www.dieselplace.com/forum/smileys/smiley2.gif I might track down connectors by then.

Gold, PM me, I might have something for you...

Answered my own question, Reliver will send the plates seperatly.

Fingers, Away for a few days and missed the first order any idea on when you may have more? or I know you are very busy but maybe PM me when available. I would love to do the combo.

I am right there with the other guy, I would pay $35 for one with plugs even though I have a fed truck with no SES set.

I'll take the connectorized version and the plate as well. http://www.dieselplace.com/forum/smileys/smiley1.gif

Been running into road blocks getting connectors. Pain in the butt. Though they look like Delphi, they don't have the PED or Delphi logos. AC Delco does not have a listing for the '04.5 or 05's yet. Even if/when I find these, they will add no less than $35 to the price just in the cost of the connectors. Looking at $50 or more for the @#$ thing.

All of the Finger Sticks are made and have been tested. I will ship Thursday. They will be going out US Post which takes about a week for California. Let me know as you recieve them.

Revised production time: 45 min/ stick to make and test. I'm working for free. http://www.dieselplace.com/forum/smileys/smiley19.gif

Would it be possible to get these through a dealer?

Yes, at $30 a connector. Way overpriced.... http://www.dieselplace.com/forum/smileys/smiley19.gif

No list, no pre-orders till this set gets installed and there is feedback. Want to do some good? Find me a good price on the connectors. Don't just give me a link. Pick up the phone and give em a call. Then post your results. With enough people bugging the suppliers, they will start to look for the connectors sensing the demand.

All Finger Sticks shipped. The plates will be coming from reliver seperately. From here, it takes on the line of a week for the USPost to deliver to California. Let me know as you recieve these things.

Enjoy.

hey, hey, Found the manufacturer of the plugs. Sumitomo Wiring Systems Ltd. Sumitomo (http://swsct.sws.co.jp/index_e.html)

EGR is a DL style connector. Housing PN 6195-0024 (male) and 6195-0021 (female)

The MAF housing is an SL series PN 6189-0657 (Female only!)

Find me a distributer here in the states.

Fingers, wouldn't you need a inline style connector, with the finger stick wires attached to it that way you would unplug the maf and egr connectors, snap the inline connector in place and then re-attach the device? Otherwise you would have to have at least 4 connectors for each finger stick (2 males and 2 females) and there isn't a male connector for the egr connector avalible from this mfg. or is there?


Just my ohpinyunhttp://www.dieselplace.com/forum/smileys/smiley24.gif


JLew

Great idea JLew, now find an inline. Heck, I was overjoyed just to find the ones I did!! http://www.dieselplace.com/forum/smileys/smiley1.gif My point being I don't think the inlines exists. Right now, the MAF Male connector doesn't exist that I know of, but I am still looking. 4 M/F will work just as well as 2 inlines.

Still need a domestic supplier for the SWS connectors. Anyone?

Round 2 on getting measurements on the egr vacuum sensor for the LB7 w/ CA emissions:


Initially I tested the LT GRN lead on chassis ground and got nothing. So this morning I did the GRY to ground and got about 5.07v during warmup and then during the egr test cycle it went to about 5.10v and back to the 5.07v afterward and stayed there.


Then I tested the ORG/BLK to ground (it's easy to hear when the egr test cycles, there's what sounds like sparking similar to a rapid pilot ignitor on a stove and the engine retards during the test). That line was steady at about .12v and didn't change when the egr cycled.


Then I retested the LT GRN and this time got about .92v steady, but during the egr test it went down to .85v briefly, then went back up to .92v even though the egr was on constant. So I pulled the vacuum line from the egr valve and the voltage dropped to .85v again and stayed there until I replaced the vacuum line. I'm figuring that the drop in voltage during the egr on/off test was the sensor reacting to the vacuum drop opening the egr valve, then the vacuum was replaced the reading went back up. I did this test twice and got the same results both times.

Wow, millivolt differences. Let me cipher on that a little. http://www.dieselplace.com/forum/smileys/smiley23.gif Totally differnet scale than I was expecting.

yea, me too. I'd like to find out more about the actual sensor as well just to verify those numbers...

Iam new to the forum, but very interested in the circuit with plugs. thought my brother in law (aerospace shop) could make a plate if i could get a cooler block gasket from G.M parts dept. Maybe someone could tell me true or false, I have a lly and put 4 inch turbo back exhust along with mac air induction, hypertech 3. After a while DTC P0401,P0404 Egr codes came in. Dealer said is do to loss of back pressure since i mod. exhust.


Also is the circuit interupter the only way to make that stupid light stay off?

First off, welcome to the forum.

The sticks have just been sent out with the vast majority of them hitting california. Many are running exhaust kits that are causing codes. In theory, this mod will cure the codes, but we will have to see what actually happens in the field.

I posted the schematic here if you want to get your brother in law to build you your own circuit. I will not be making any more till I get some feedback.

I am in for one, great idea.





drmtexas@yahoo.com

Wow, People are already recieving thier sticks. Here are the directions:



First a warning; Do not reverse the power and ground connections!!!
Doing so will fry the circuit for sure. Double, triple check your
connections. Next, A reminder that you are doing this at your own
risk. I can not, will not be responsable for any damages,
problems, warrentee, marital disputes or ANYTHING that is a result of
this mod.



To start the hook up, you will need some wire splices/taps from the
local parts store and a wire cutter. OK, here is the labeled
stick picture:



http://www.dieselplace.com/forum/uploads/Fingers/2004-10-02_122056_mvc-580f.jpg



On the side with two leads, the Green is the MAF OUT and the long Black
is the EGR. On the three lead side, Green is MAF IN, Red Power, and
Black is ground. Make sure you know which is which.



At the MAF connector, The wires are as labeled in the picture.
Pull open the wire loom (plastic corrigation) to gain easy access to
the wires. Cut the MAF IN (yellow wire) and splice the connector side
of the cut wire to the MAF IN (MI) wire on the circuit. Splice
the other half (engine side) to the MAF OUT (MO) on the circuit.
You are done cutting wires!!



The Power Wire taps into the middle pink wire coming from the connector
and the Ground to the gray wire between the MAF IN and Power wires as
shown in the picture. Do not cut these wires!

http://mysite.verizon.net/mcelravy1/graphics/MAF_connector.jpg



Finally, the long Black wire taps into the EGR signal wire. The Signal
wire is the blue lower left wire coming out of the EGR connector shown
and labed below. Again, open up the wire loom to gain access to the
wire, do not cut the wire, just tap into it..







http://mysite.verizon.net/mcelravy1/graphics/EGR_connector.jpg



Secure the stick with some wire ties or tape to the harness and you are done.



Question?? Post them here so we can all learn.

Thanks fingers, i will work on getting the blocker plate but definitly want in on the next shipment of sticks.

Well after watching the Dodgers make that awesome comeback, I went out and installed my Fingers stick. I first cleared the codes with my OBD II scanner. These were PO401 and PO404 that I was getting with the EGR plugged in and using the block off plate. Then followed the instructions that Fingers posted, to the letter, (which I might add were excellent), checked and double checked all connections. Started her up and after three miles the CEL came back on. http://www.dieselplace.com/forum/smileys/smiley5.gifThe codes I picked up were PO401 and PO404, no surprise there, and an additional two codes. PO406, (ERG flow sensor A circuit high input), and PO1404, (Aux emission controls). I removed the stick and codes are back to where they were before, PO401 and PO404. Anyone else with Cali emissions do any better? Mac

Mac, could you post a picture of your stick, chip side up? It sounds
like the EGR and MAF OUT wires are incorrect/swapped.
Probably my fault. The EGR wire on the circuit should have no voltage
what so ever. Just tested a copy of the stick here to make sure.





Everyone hold off till I get a chance to look into this.....solve it once, everyone is better off.



Thanks for the quick response MAC.














Edited by: Fingers

Sure Fingers, here it is. Just to let you know, The wiring was installed as per your detailed instructions. Mac


Edit: The pictures look like the wires are chafed. There not, just the poor quality camera.

Dumb question MAC. Was the EGR plugged in?

did it melt off that way? or did you peal it?



That's a fried chip.






Edited by: Fingers

Return it to me and I wil refund your money mac. I want to take a
better look at it. I can/will send you the one off my truck if you want.

Yes the EGR was plugged in.


It melted away. I tied it to the adjacent large wiring harness away from any heat source.


I'll send it back to on Monday. Don't worry about the money. Mac

The chip fried. Might have been from me. My test rig was, well, crude.
If the IC gets power and ground reversed, it overheats when hooked up
the correct way. Another vote for connectors I guess.http://www.dieselplace.com/forum/smileys/smiley1.gif I will send you my stick. I don't want your money if it does not work for you.



As a note to everyone else. If the stick gets hot when you start the
motor, the chip is fried. Uninstall, send it back. Goes back to
my original precaution about getting power and ground reversed.Looks like I am guilty on this one. http://www.dieselplace.com/forum/smileys/smiley19.gif



Install at will folks. If anyone is skittish about installing now and
wants to return the stick, I will refund your money. Email me if you
are going to return it so I know who's who. This install is not for the
weak of heart.

LOL this is crazy. Hay Fingers I can't wait to see what happens when I put in in my truck. LOL. Hay I talked to Edge and they said they are hoping to have a reflash for our problems. He told me they have talked to you directly. I hope we can all beat this thing.http://www.dieselplace.com/forum/smileys/smiley4.gif

For your next version, what about a reverse polarity diode and a fuse. Just to be on the safe side. I'd be worried at possibly damaging the ecm with reverse polarity. Not exactly sure I understand the issue so maybe I am out in left field.

LOL this is crazy. Hay Fingers I can't wait to see what happens when I put in in my truck. LOL. Hay I talked to Edge and they said they are hoping to have a reflash for our problems. He told me they have talked to you directly. I hope we can all beat this thing.http://www.dieselplace.com/forum/smileys/smiley4.gif


You mean a reflash so that if you disconnect the EGR it doesn't set codes? If not, what problems are you referring too?

I have had no contact with Edge or any other Box company about using
this. They are welcome to it. Heck, I would be flattered it someone
would pick it up besides me. As is, I can't sleep tonight trying to
make sure I understand what is going on.



I thought about the diode the first time I fried a chip. At the time I
couldn't get my arms around all the falure modes since one diode would
not provide a stronge defense. (long story but spelled out in the chips
spec sheet) The ECM inputs are virtually all protected against short
and overvoltage. Thus the codes MAC saw. I had looked into that early
in my research. for fear of hurting my ECM. Connectors would
solve this problemhttp://www.dieselplace.com/forum/smileys/smiley1.gif But that is not going
to help today. Future designs will have to balance robustness with
complexity(cost). I am still open on that front. This current design
was intended for me and maybe a few other brave souls. Proof of
concept. SO I kept it painfully simple. I even used the MAF signal to
trim the EGR signal and save using another chip.



Rotax, if you have doubts or fears, return the stick for a full refund plus return postage. That goes for everyone.

I'm not sure if I speak for everyone, but when it comes to avoiding all of the bad stuff that gets circulated throught the motor while the EGR is opened, I would be willing to pay more than the $22 listed for the present setup. $50-$100 would still be OK in my book for a nice set-up with connectors (after the R&amp;D has been completed.) And I thought I stayed up late.... Edited by: Reineke

Hay Fingers I have no doubts or fears I was just busting balls. I just want someone to figure this thing out. I am willing to pay 200. for this fix even more . I just called edge and they said they are following this post. He really did tell me he talked to you on the phone. He said they hope they can get a reflash for this problem. They are aware of the problen when changing the exhaust and would love to get it resolved. I am no worried about 22 dollars at all. I want to thank you for all you efforts and help. If it does not work for me we will figure out something. Thanks to all of you guys helping on this. We here in Calif. really mean it.

Bothers me that I let a bad one out. Bothers me more that I think there will be others because of <span style="font-weight: bold;">my</span> poor quality control. There were only 24 total made, but now the whole production run is a blur to me. http://www.dieselplace.com/forum/smileys/smiley29.gif

Fingers, I'm sending this stick back tomorrow via snall mail. I probably just got a bad one. No harm done. If you could please send me another one I would be greatfull. Mac

Hay Fingers I got the stick today. I will try to get some time to put in in.I'm in Calif. so they got here fast. Is there a problem with the instructions or was it just a bad stick. I will wait for an answer before I install.


Thanks Again

Fingers, I'm sending this stick back tomorrow via
snall mail. I probably just got a bad one. No harm done. If you could
please send me another one I would be greatfull. Mac



I removed the one from my truck. I will attatch some fresh wires, new raychem and send it out to you mac.



Rotax, go ahead, install it. I can not see a problem with the
instrucitons. Keep us informed. Do check the stick as soon as you
start up to see if it is getting hot. They should generate zero heat if
they are working correctly.

http://www.dieselplace.com/forum/smileys/smiley17.gifYa Baby. I just installed the stick and drove my truck around. No lights and no codes. I have restarted it 10 times already. Normally after 3 starts it sets codes. I am going to drive around a little more right now. It'll set codes for sure this trip if it is going to set them at all. I will repost in 2 hrs. Just to let people know I have a 05 Calif. truck with MBRP exhaust and I am running the Edge juice. In Calif. the truck set codes just from the exhaust. (removing the cat). The code are the same as you guys get when blocking off the EGR. I have no codes so far from Fingers stick. I am waiting for the EGR block off plate from Fingers. Let you no soon. Thank you Fingers so far you might be GOD.http://www.dieselplace.com/forum/smileys/smiley17.gif


Thanks Stevehttp://www.dieselplace.com/forum/smileys/smiley4.gifhttp://www.dieselplace.com/forum/smileys/smiley2.gif


http://www.dieselplace.com/forum/smileys/smiley17.gifhttp://www.dieselplace.com/forum/smileys/smiley17.gif

Hay guys just got back from my last drive. No codes.http://www.dieselplace.com/forum/smileys/smiley1.gif I am so happy. I will drive my truck to work tomorrow. That will be the final test. Every time I have driven it to my work the codes have set. 140 miles round trip. I really feel the codes would have set already just from the driving I have done today. Fingers is the man. I hope Fingers gets together with a company and markets these with connectors. I feel he deserves a tone of money for this fix. On a 50,000. truck $200. would be well worth this fix with connectors. I can't thank him enough for the help and to everyone else who helps http://www.dieselplace.com/forum/smileys/smiley17.gifhere in this forum. I will let you no tomorrow if it is for sure.


Thanks again Fingers.


Steve

<div style="text-align: center;">Well, I feel better anyway. I should sleep well tonight too. Glad your happy Steve.

Give that man a blue ribbon, right on super fingers well done. Nice feedback, when do you think i could paypal you for a stick plate combo.


Thanks, Dave
http://www.dieselplace.com/forum/smileys/smiley20.gif

It is 100% official . Fingers stick works perfict. I have driven 300 miles and 20 starts with no codes or lights. My truck runs great. http://www.dieselplace.com/forum/smileys/smiley4.gif Fingers is the man.http://www.dieselplace.com/forum/smileys/smiley4.gif Thanks again. The install was easy and took about 20 min. I love this Forum. Thanks for all the help guys. I just need the plate now. For you guys who have taken your cats off here in Calif. this finger works for the egr codes as well as for the egr block off plate mod. Our trucks here set codes with 4" exhaust. Fingers mod fixed my problems. http://www.dieselplace.com/forum/smileys/smiley36.gifhttp://www.dieselplace.com/forum/smileys/smiley4.gifhttp://www.dieselplace.com/forum/smileys/smiley10.gif

I haven't seen mine in the mail yet, but it should be here by the weekend. I guess that is when my truck will get fingered http://www.dieselplace.com/forum/smileys/smiley2.gif

Odd how the US Post works.http://www.dieselplace.com/forum/smileys/smiley1.gif I would
have thought everyone in California would have gotten thiers within a
day or two of each other. If you got your stick, speak up. I need
feedback.

Looking for it in the snail mail. http://www.dieselplace.com/forum/smileys/smiley7.gif Guess it will be here by the weekend. Same as the plate waited for a while thats the postal service http://www.dieselplace.com/forum/smileys/smiley36.gif

Got mine Monday in Reno, installed last night. The truck started once with no codes. I'll let you know more after some miles today.


Thanks for your effort on this Fingers.


Dennis

Fingers! Got mine today. Thanks a lot, buddy! Now, I need that block off plate! http://www.dieselplace.com/forum/smileys/smiley1.gif



I will try to get it installed this weekend.

Got your Fingers stick today in the mail and installed it. No codes! Took it out for a 10 minute ride and still no CEL or codes. I have an OBDII scanner hooked up and before the codes were always read in the scanner even when the CEL was not on. I'm very optimistic. I'll post back tomorrow. I should have at least 10 starts and 75 miles on her by then. Fingers, thanks for sending out your own personnel stick. I sent mine back out in the mail Monday morning. Your our hero!!http://www.dieselplace.com/forum/smileys/smiley32.gifhttp://www.dieselplace.com/forum/smileys/smiley32.gifhttp://www.dieselplace.com/forum/smileys/smiley32.gifhttp://www.dieselplace.com/forum/smileys/smiley32.gifhttp://www.dieselplace.com/forum/smileys/smiley32.gifhttp://www.dieselplace.com/forum/smileys/smiley32.gifhttp://www.dieselplace.com/forum/smileys/smiley32.gifhttp://www.dieselplace.com/forum/smileys/smiley32.gifhttp://www.dieselplace.com/forum/smileys/smiley32.gifhttp://www.dieselplace.com/forum/smileys/smiley32.gifhttp://www.dieselplace.com/forum/smileys/smiley32.gifhttp://www.dieselplace.com/forum/smileys/smiley32.gifhttp://www.dieselplace.com/forum/smileys/smiley32.gifhttp://www.dieselplace.com/forum/smileys/smiley32.gifhttp://www.dieselplace.com/forum/smileys/smiley32.gifhttp://www.dieselplace.com/forum/smileys/smiley32.gifhttp://www.dieselplace.com/forum/smileys/smiley32.gifhttp://www.dieselplace.com/forum/smileys/smiley32.gifEdited by: mac1234

After the fourth start, the truck threw P0401, P0404 codes. Checked connections &amp; everything appears OK. Doesn't look like it got hot.


Dennis

A little more info please Dennis. Are you running an EGR Plate? ( I
assume you are) Did you
set codes when you changed your exhaust, but before the plate?
California emissions? Light or
just codes?? Given your not getting a MAF code, MAF signall is passing
through the stick.. Very good chance that the wire from the EGR to the
Stick is not making good contact. I would focus on that. Codes will not
set on the first run until the EGR test, which happens only after the
engine is warmed up.



Fingers




Edited by: Fingers

hey fingers good job. no lites no more codes. with blocked plate.the truck seems a little sluggish. with a little knock at 2500 rpm when cruising down street.that was not there before the finger stick.any one else experiencing this.

Hay guys I'm on day 4 and everything is still perfict. No lights no codes. I got my plate but I have not installed it yet. Do you guys think it works to increase fuel economy.


Thanks

Sorry Fingers for the lack of info. Yes I do have the plate installed. Exhaust is cat-back &amp; has been installed for a while with no issues. The truck does have CA emmissions &amp; I have gotten a light with codes.


I'll mess with the connection @ the EGR plug when I get a chance. Thanks,


Dennis

Update: I rechecked connections this morning &amp; the EGR tap wasn't closed completly. I pressed it closed, cleared all codes &amp; put about 150 miles with probably ten to twelve start ups &amp; no light, no codes!


Thanks again Fingers for the time &amp; effort to put this together. Now to pull the cat.


Dennis

I put 75 miles on the truck today with about 15 starts and no codes. Thanks again Fingers for all your effort. Sure is nice not to see that CEL on all the time. Mac





Edit: I just received my Fingers block off plate today. It will be replacing one I made and installed last month.

From what I can gather, the California LLY's had a more agressive EGR
schedule than the others. One benifit was a quieter diesel. Mine has
knocked harder at 2500 or so when the pilot injection shuts down since
new. That is probably what you are hearing.



Per design, at higher flow rates, the alterations to the MAF signal is reduced to zero.

Got the failed Stick back from Mac today. The chip failure looks like a
reverse power hook up. Don't know when or how that happened. Doesn't
matter.These chips have Zero tolerence for that. http://www.dieselplace.com/forum/smileys/smiley5.gif All
the traces are still good. One resistor is damaged, but still
functional. I should be able to rebuild it. My office smells like
a burned out stereo now.http://www.dieselplace.com/forum/smileys/hihi.gif

I am new, with a 04 Duramax. I have no problems with it. I would like to improve fuel economy, and was wondering if your mod would help with doing so. I have not done anything to the exhaust. Would I benefit modifing the exhaust? Secondly the truck is a 4x4, I would like to put larger tires on the truck to be able to drive in the sand pulling a 26' inclosed trailer, any suggetions? Thanks, John.

Gonna make you read some of the EGR threads and decide for yourself. It
is a lot of info, but only YOU can dicide what is good for YOUR truck.
How's that for non-commital?http://www.dieselplace.com/forum/smileys/smiley1.gif



FWIW, I run EGR blocked, Finger Stick installed to kill the codes and
365/65-16 tires without a lift. I am NOT your mainstream Dmax owner.

Here's a question I haven't heard mentioned before.


Is there any way that someone with the potential to reprogram the actual PCM could accomplish the same thing as the "Finger Stick?"


Not to knock Finger's work whatsoever, I'm just curious if a company such as Wester's Garage that routinely reprograms the actual GM PCM could do essentially the same thing.

This was mentioned in another thread and Yes, it can be done with
reprogramming. Most programmers, however, are not changing the
actual code, only the fuel tables. There is a big vacuum
when it comes to LLY privy code programmers. I think Diesel Tech has
some better insight here. If I understand correctly, he has been
rearranging code in the LLY ECMs.



I am not gung ho about going into full production for this reason, and other legal matters. Have to admit, the stick is simple. http://www.dieselplace.com/forum/smileys/smiley1.gif IF you only want to deal with the EGR, it's the cheapest/simplest route Stacks well too.

Fingers,


In your experience would you say this EGR mod would improve fuel economy (my truck is stock)? Also running large tires like you do, have had any problems like tire rub, drop in fuel economy,codes? I am also wondering where is a good place to pick up a set of electric telescoping mirrors that won't cost a arm and a leg as my truck doesn't have them? Thanks, John.

fINGERS THUMBS UP ON THE 05 thanks again works great John

20 some of these things out there and so few installed.http://www.dieselplace.com/forum/smileys/smiley19.gif

Fingers,



I got my plate today (stick came a few days ago), but will not be able
to install this weekend. it will have to be next weekend. Thank you for
your hard work on these!

Fingers -

Stick installed. All is OK with 100 miles on. You have been added to my
DieselPlace Hall of Fame.

Incidentally, IMHO, nobody should be using an EGR block without this
device OR a very regular check of their DTC's with a scanner. Upon the
install I found one (unrelated) that registered sometime since I put the
plate in a few weeks ago. It had the potential of putting me in limp mode.
All fixed now.

Anybody know what evidence of this mod shows up on the Tech II? I have
a Tech II but am unfamiliar with what "normal" looks like. I tend to think
of these things after the fact. http://www.dieselplace.com/forum/smileys/smiley9.gif

Thanks.

Thanks for the input, John.http://www.dieselplace.com/forum/smileys/smiley1.gif

Fingers,


I have the plate and stick installed, unfortunately the CEL remained lit. Drove over to the service department and had codes p0106, p0401 and p0404 removed. Following the third start the CEL lit again. All the connections seem to be in order and the chip is not hot. I have the Edge/Attitude and Flowmaster catback exhaust installed. Any suggestions?

P0106 can't be right. That is for a gas engine. The EGR is plugged in, right?

Fingers,


I'll check the EGR plug tonight. I believe the P0106 error code was the result of installing the blocker plate a month ago. Other then the CEL being lit, the Duramax runs well with good power and satisfactory mileage.

I'll repeat, the P0106 does not apply to diesels. It is a MAP sensor
out of range error. There is no MAP sensor on the diesels. 401 and 404
are typical for the EGR being blocked.



I suspect the connections at the MAF sensor, not the EGR. You probably
got P0101 which would make sense. Please double check the DTC that was
thrown.

Fingers;


What is the deal with the codes? I have a blocker plate installed with no lights. Seems to me that all you need to do is clear any codes before going for service. Do the codes cause other problems or are they just stored for inf until cleared ? I'm located in GA with FED emissions which brings up another question. I've heard that the LLY's are the same nationwide and that they will meet the 2007 emission standards. Is that true ?

Fingers, I have a little different question.


My California truck throws P0404 &amp; P0401 with the cat removed and the EGR stock. I haven't installed the Finger Sick and Plate because I want to have the dealer flash the ECM with the latest calibration and planned to install the Stick and Plate after the dealer visit.


Even if I clear the codes prior to leaving it at the dealer, it will set them when he starts it. I don't want him to pick up the codes and start looking around for the cat, so I wanted to know if the Stick should work to eliminate the codes even with stock EGR.


After the reflash, I will install the EGR elimination kit.


Thanks

For service, you would clear the codes and remove the blocker plate..
As best I can tell, the Stick is invisible to the Tech 2, but I am not
100% positive. I do not know exactly how the codes effect engine
performance. I personally prefer to run my truck without setting codes.
The mechanicals on the LLY's are the same. The tune varies from region
to region.. My understanding is the LLY is capable of meeting the 2007
standards with just code changes.

The stick should prevent the codes from coming back. To the best of my
knowledge, it is invisible to the Tech 2. A clean instalation
will keep it hidden from view. Rotax installed only the stick with his
exhaust. and it cleared his light and codes.

Just a quick clarification, did Rotax install the Stick leaving his EGR stock (pugged in)?


ThanksEdited by: CntrlCalDmax

Yes I did install the stick with the EGR stock. It cleared all my codes. I will be putting the block off plate in this week have not made time yet. I Installed the stick very clean. The dealer will never no it's there. I put the same tubing over the stick that chevy uses but just a bigger size and taped up the ends. It looks factory.http://www.dieselplace.com/forum/smileys/smiley1.gif


Thanks Rotax

Is anyone still having problems? Please post. Or at least PM me. There
is almost enough interest to do another small run of a connectorless
version, but not enough feedback. Any Issues?

No problems here. Fingers stick and block off plate installed. Starts up on first try and runs strong. No CEL or codes. Engine temp normally 205. All stock. Mac

Thanks Mac. Come on, 23 sticks out there and only 6 feedbacks.

Fingers,



Will be doing install today sometime. I will post feedback ASAP!

hey fingers i mite of jumped the gun on my first quote. the stick works perfect with a blocked plate, mrbp exhaust,no cat down pipe.starts fine runs good no codes at all.was getting four codes before finger stick.thanks

I'll get a stick and plate if another run is made. New truck is on order, can't wait for it to get here...

Thanks Mac. Come on, 23 sticks out there and only 6 feedbacks.


Posted in the other thread:


I installed the stick this morning. EGR is still stock until I visit the dealer for ECM reflash. So far so good. Started and have driven three times and no codes. Use to get them all the time with an occasional ses light. I'll install the plate after dealer visit.

I'm leaving on a business trip this coming weekend. I should be back
mid-late November. I had hoped to of had a couple of things ready
by now, but it didn't happen. One was around 75% feedback on the sticks
already made so I could adjust the design to take care of any problems.
Another is connectors to make the hook-up easier. Neither have panned
out, so far.



I have a revision of the original stick on the board ready to go. I
have another that would work better with connectors ready also.



There was a suggestion to make these available as a kit. That would
really take the load off me, so I am considering it. Would be nice to
turn a profit.http://www.dieselplace.com/forum/smileys/smiley2.gif

Patiently waiting for the second run. I would need the kit, If memory is correct you said $22 or something for the combo. I would be willing to go $50 so you cant profit and if that isn't enough name the price. You do have some R&amp;D to recoupe http://www.dieselplace.com/forum/smileys/smiley2.gif.





Thanks

I know you have been working on this without too much luck, but what are the chances of the second batch coming with connectors? Thank you for taking your time to do this!

http://dieselplace.com/forum/smileys/smiley20.gif I am interested in making a purchase of a package deal for the finger-stick including a plate. It would be nice if it had connectors (plug and play). Keep me in mind if more is made, thanks.http://www.dieselplace.com/forum/smileys/smiley32.gif Edited by: 04DMCC4X4

I'm in no matter the price..

Fingers,



Will be doing install today sometime. I will post feedback ASAP!






Well??

I am in too. Let me know when you want the money.


Thanks again for doing all the work

As does every smoke box that people put on their trucks.http://www.dieselplace.com/forum/smileys/smiley1.gif
However, The LLY far exceeds the EPA standards in effect at this time.
(beats the 2007 standard?) I'm no lawyer, but as long as the vehicle
passes the applicable standard for that year, you are good to go, as an
owner anyway. There is a certification process for modifications, but
I'm not going there. I know a lot of the aftermarket turbo/supercharger
companies have gotten certification.



The reality is that the EPA has tasked the individual states with
managment of the Air Pollution control programs for vehicles (testing,
enforcement). California, as we all know, has decided to exceed the Fed
standards with their program. So, though it is not in the spirit
of the Clean Air Act, the only government the owner needs to worry
about is his local State inspections and enforcement.



As always, use at your own risk.

Hey guys,I've been busy, but I got the Finger Stick installed with plate and my truck runs like a champ. I've put about 1000 miles on since I installed the stick. Ya done good Fingers!

http://www.dieselplace.com/forum/smileys/hihi.gif

i am in for the combo pack. as soon as it is available please let me know. i can't stand looking at the check engine light after i installed the staight pipe. let me know when and how to order it. i can't wait!

Sorry for the delay...I totally spaced on the update to you! I installed with no issues. I notice no change whatsoever in the way the truck behaves so far. Got about 800 miles on the blocker and finger stick.


Fingers,

Will be doing install today sometime. I will post feedback ASAP!


Well??

I plan to straight pipe my 05 soon. Definatly dont want to run around with the SES light on.





I dont exactly like to trust myself wiring things, so a plug in play unit would be nice.





Also willing to pay more for a plug and play unitEdited by: 05DMAX

I would be intersted in the stick on your next go around. I was
planning on removing the cat and want to make sure the light stays
off. I have no problem with splicing wires.

Thanks

Let's see. Your first post here was asking for help on a paper you were writing on the LLY turbo. You were given all the help you ask for. Now you turn around and begin preaching to the folks on this board about their mods. Not just this thread but on another one as well. BTW in reference to your statement on the other thread. These mods can't LEGALLY void a warranty unless the mod causes the problem. Now, in reality, many dealers will still try to void it whether or not that was the case.

Fingers,


I need one or you sticks and a blockoff plate. Please start making these agian soon!!! I just removed the cat from my LLY and damn it if that light came on. I want to bounce the egr too. When do you plan on creating more?

I will take one when the next ones are made.http://www.dieselplace.com/forum/smileys/smiley20.gif

Ghost69_68,


Do you have any electronic pictures of your truck? Your 3" body lift interest me. All the body lifts I have found for silverado's say they wont work on the diesel. If you have one that will, please share the info and if you have any picks, I would like to take a look.

Back to the topic at hand:


I just installed the 4" downpipe that I ordered from rpmoutlet.com, fit perfectly. I ran it for 2 days, and then that fricking light came on. Im tired of running it into the dealer and Im tired of disconnecting the battery to reset that computer, so I bought one of the OBD-II code readers jabberwackys. It gave me the insufficient flow code for the EGR. I erased them all, then I drove the like normal for about 3 days and re-checked, no codes? WTF, Im thinking that the EGR gets checked at start up, and If I just hop in a go the EGR isnt getting the flow becasue the engine is working, but If I turn on and let it sit for a moment the egr gets the flow it needs for the test. Does this make any sense to anyone, or is my truck just doing random crap? Its a california truck also(I knew I should have moved to Billings)

I am interested in making a purchase of a package deal for the finger-stick including a plate. I would prefer it had connectors (plug and play). Put me on you list for the next round.

Fingers


Can you put me on list for stick and wiring also blocking plate. I ask about getting a stick but don't know if I got on the list


thanks

Nice work. When you brew up your next batch I would like to buy one stick and a plate. Let us know when you want us to inendate your pay pal account with $$$$$$$$.

Dang,


I got all excited too. I put the 6" on mine and its not enough for me. Im either going to get a fabtech 8" a whiplash 10-12 or a CST 9-11. I have not decided which yet, everyone usually has something bad to say about two of them, and they usually have the 3rd installed on there truck. Would have been nice though if a 3" body lift were available, then I could run 38" and get rid of these 35" POS. Oh well.

Thats Mr. Fingers


Please put me on the list for plate and stick along with the rest of this whole forum.


thanks

Fingers, When do you expect to have anymore available?

Oh ya, me too Still waiting for a run of those sticks with connectors, already have the plate

I am about a week from getting back home from this business trip. http://www.dieselplace.com/forum/smileys/smiley1.gif The connector saga continues, but looks grim.



However, I have had an idea. Most of you asking for the stick
have already purchased an add on box/tuner. The connections for the EGR
and MAF go through the connectors used by these boxes. Actually, just
the harness. SO......



What do you folks think about sending me your boxes and I will patch in
the defeat circuit? Standard disclaimer for damage yada yada. With
enough response, I will talk to the manufacturers and get thier
feedback.

So fingers, you can wire it right into the Edge?

yep. Actually, the harness. The Edge does <font color=RED> not </font> appear to use the EGR or MAF signlas.



Edit in <font color=RED> red </font>


Edited by: Fingers

Are you going to make anymore sticks? If not could I get the resistor value on the board?

What happened with the stick, fingers?

I think that's what happened to it.

Oh, so being a week out from home happenede to it. I see...


Let me re-phrase the question so everyone may understand.


Fingers,


What is motivation for wanted to make the changes to the wiring harness on the edge boxes instead of using the "stick"?


I apologize for my ambiguity

I gotcha now, no need to apoligize, I just misread. I think he
was talking about wiring a stick into the harness on an Edge or other
box. That way noone would have to worry about the plugs anymore,
and if you wanted to go in for dealer work, the whole thing would come
off when you unplugged the box.



Thanks,

Dennis

Dennis,


Im just playin around man. I guess if you can't hear the axcent that I would have said that in its not really funny. Hmm, damn this written language crap. The axcent was the stuffy harvard grad, which would have been in contrast to the "I rally don car bout notin" axcent I normally speak in. No amount of education will remove me from redneckdom. You take me out of the country, but you can't take the country out of me. &nb sp;


Anyway, so what you are saying is that there is nothing wrong with the stick. Its just a different way to do it.


By the way, what is Hi+Fog Mod?

LOLhttp://www.dieselplace.com/forum/smileys/hihi.gif



Nothin' wrong with the stick. . . yep, just a different way to do it. . .



Hi+Fog Mid is a diod stuck between the two relays so the Fog Lights stay on when I switch to Hi Beams.



Dennis

Sounds good fingers but if i am understanding right ( i used my orignial harness off old air box, and i have a hypertec 3 programmer that requires to unplug after rewriting computer.) i may not have the harness to send you. If so the finger stick alone will more than allign all the planets in my truck.

It was just an idea folks. I will do another run of sticks when I get home.

Sign me up, stick/plate combo and I dont mind wiring it in (non-connector).

Put me in for a stick also. I'm not worried about the connectors. I have a wire stripper and I am not afraid to use it.http://www.dieselplace.com/forum/smileys/smiley4.gif

Put me on the list for a stick and block off plate. Can pay with paypal just let me know how much.....I really need this ASAP! Thanks

Well, I'm back home. I will be doing another run of the sticks by
popular demand. I expect all the parts to arrive within the next
couple of weeks. I will post ordering info shortly. NO connectors! I am
not willing to dish out the $3000 plus to meet the minimums. I will
post which wires you can connect to on the Edge and other plug in boxes
for a removable installation.



It's good to be home.

I thought after all this time someone on here would've found connecters, sadhttp://www.dieselplace.com/forum/smileys/smiley19.gif to hear, I really wanted one with connecters.


Oh well I guess I will wait and hope something turns up in the futurehttp://www.dieselplace.com/forum/smileys/smiley1.gif

<font color="#0000ff" size="3">Oh well I guess I will wait and hope something turns up in the futurehttp://www.dieselplace.com/forum/smileys/smiley1.gif</font>



Connectors ARE available. Just the minimum order is 500 Units and I am
not willing to shell out the $3000 plus bucks to meet the minimum.

I totally understand, maybe some else might get lucky and find some affordablehttp://www.dieselplace.com/forum/smileys/smiley4.gif

The connectors are pretty affordable, its just that they require a minimum purchase. Most of these connectors are purchased for major production runs, so the small run of "Finger Sticks" requires that he purchase what the supplier orders, thus the minimums.


No one wants a boat load of these things sitting around collecting dust with little or no demand and when you start adding up all the stuff required to make up the connectors at the minimum order quantity, it adds up pretty quick.

I'll take a stick too, if you could let us know how much, I already have the plate and it works great!

Finger Sticks available:

What is the deal with the codes? I have a
blocker plate installed with no lights. Seems to me that all you
need to do is clear any codes before going for service. <span style="font-weight: bold;">Do
the codes cause other problems or are they just stored for inf until
cleared ? </span> I'm located in GA with FED emissions which brings up
another question. I've heard that the LLY's are the same
nationwide and that they will meet the 2007 emission standards.
Is that true ?</font>



For service, you would clear the codes and remove the blocker plate..
As best I can tell, the Stick is invisible to the Tech 2, but I am not
100% positive. I do not know exactly how the codes effect engine
performance. I personally prefer to run my truck without setting codes.
The mechanicals on the LLY's are the same. The tune varies from region
to region.. My understanding is the LLY is capable of meeting the 2007
standards with just code changes.





We never did get the bolded question above answered as to whether
"codes" effect engine performance or are they just in the PCM for
diagnostic purposes?



I'm running with the blocker plate and no SES light (no fingers
stick). I'm sure that I'm setting codes but do they do any
harm? If there is no harm in having codes present - what would be
the need for the stick if your not having a SES light issue??



BTW - I read all 12 pages of this thread to make sure it wasn't answered- My eyes hurt!!http://www.dieselplace.com/forum/smileys/hihi.gif

"Do the codes cause other problems or are they just stored for inf until cleared ? "


In my case it turns on the SES light. The stick eliminates that from happening.

I am comfortable in asserting that essentially any failed
sensor or system that sets a code puts the ECM in some
form of limp mode. Including the EGR. However, without the
software in front of me, or a manual with a detailed
explination, I don't know exactly what it is doing.

My guess is it will limit/change fuel delivery, to reduce
combustion temps, and almost certainly change the VVT
mapping. I wouldn't be surprized if the timing changed too.

I have observed changes on my engine with all sorts of
combinations of plate and stick and unplug. But they are
limited to my truck, so I hesitate to expand on it as any kind of
generalization. I might be critisized as being biased anyway. I
would rather those that have made the mod post their
observations. Then YOU be the judge.

One thing for sure, the California boys like shutting off the
SES light.

<span style="font-weight: bold;"><font face="Arial" size="2">In my case it turns on the SES light. The stick eliminates that from happening.</font></span>






Thanks - I see how the stick is useful to turn off the SES light. I
just don't plan on getting the stick because I don't have that problem
and I'm just wondering if there is a risk of the PCM re-adjusting fuel
flow etc. if it continually is setting codes.

This may or may not be related, but if anyone could shed some light on this subject.



Will the egr defeat also prevent codes from being thrown when removing the cat on CA trucks?

Yes

Great! Thanks for the info, cant wait to get the stick!

This may or may not be related, but if anyone could shed some light on this subject.

To be more specific, 401 and 406 for sure. Some have had luck with the boost codes too, but not enough to convince me, yet.

I have a LB7 DMAX. If I straight pipe, will a EGR mofication be required or is this only
a problem with the new LLY DMAX?

Wow, People are already recieving thier sticks. Here are the directions:



First a warning; Do not reverse the power and ground connections!!!
Doing so will fry the circuit for sure. Double, triple check your
connections. Next, A reminder that you are doing this at your own
risk. I can not, will not be responsable for any damages,
problems, warrentee, marital disputes or ANYTHING that is a result of
this mod.



To start the hook up, you will need some wire splices/taps from the
local parts store and a wire cutter. OK, here is the labeled
stick picture:



http://www.dieselplace.com/forum/uploads/Fingers/2004-10-02_122056_mvc-580f.jpg



On the side with two leads, the Green is the MAF OUT and the long Black
is the EGR. On the three lead side, Green is MAF IN, Red Power, and
Black is ground. Make sure you know which is which.



At the MAF connector, The wires are as labeled in the picture.
Pull open the wire loom (plastic corrigation) to gain easy access to
the wires. Cut the MAF IN (yellow wire) and splice the connector side
of the cut wire to the MAF IN (MI) wire on the circuit. Splice
the other half (engine side) to the MAF OUT (MO) on the circuit.
You are done cutting wires!!



The Power Wire taps into the middle pink wire coming from the connector
and the Ground to the gray wire between the MAF IN and Power wires as
shown in the picture. Do not cut these wires!

http://mysite.verizon.net/mcelravy1/graphics/MAF_connector.jpg



Finally, the long Black wire taps into the EGR signal wire. The Signal
wire is the blue lower left wire coming out of the EGR connector shown
and labed below. Again, open up the wire loom to gain access to the
wire, do not cut the wire, just tap into it..







http://mysite.verizon.net/mcelravy1/graphics/EGR_connector.jpg



Secure the stick with some wire ties or tape to the harness and you are done.



Question?? Post them here so we can all learn.
Been reading what seems like a thousand posts (okay, may only be about 850). When I recieved my "stick" it has different wiring colors than the pictures posted, and the EGR signal wire seems short.

Are there different instructions for the later versions?

Thanks for the bandwidth,

Julian

Why not just disconnect EGR Plug like others have done without codes being set off.:confused:

The california boys/girls get a light and who knows what if anything the ECM is doing to compensate.

The links dont work for me. When will the next batch be available? I am Fixen to do the exhaust on my new 05 GMC But I dont want any codes etc.Let me know if and when the sticks are available. I kave a Cal. Truck and I am shure I will be having a problem.I will also be adding a Edge also.
Let me know when avalable.

Fixed the links

Thanks Fingers for the quick pointing!
