I am getting a PMD/6foot harness/cooler from edam ($64 + Shipping) on ebay
I am going to leave the stock PMD on the IP as a backup because it is good and install the new PMD in the Bumper.
My question is does the pmd have a risistor built in or i have to get a risistor for my new PMD or can it run without one.

PMD does not have a resistor built in. You will need to get one. Talk to edam he will sell you one with your new PMD and harness.

$64+Shipping is a **cking good price for all three items. Are you sure it's not just for the PMD?

I don't think a resistor comes with the PMD, unless the seller explicitly states it. If not sure which resistor to go with, the #5 should be okay. They go for about $20+Shipping on eBay or ask the seller if he carries them.

Yes all 3 items $64 +Shipping (good used PMD) i have been out bid for months it goes for over $100 every time Just keep on bidding soon one slips through
BTW i see a #9 risistor on ebay for about $25.00 i am going to bid on it

If I were you, I would not used any "good" "used" PMD. I know it is cheaper but if it ever break, it will become more expensive. If PMD has seen the heat of the engine, it will be toast one way or another. There is no test that can mimick the heat of an engine compartment. Try to buy the new DTECH PMD, I heard they are much better. Of course, everything are manufactured so there may be bad quality part. Just my 2 cents.

personally i think with a back-up on the pump you have no threats, mine was roasting, stalling ect and when i moved it to the bumper it fixed the issues, so now i have my "good" but "used" pmd i bought to replace my original in my glovebox... you got a killer deal on that. I got a #9 from kennedy, was pretty cheap

Dang! And 2x Dang!!

At these prices, try, no, get another PMD (spare in hand instead of crawling over a hot diesel engine to plug in the one mounted on the IP -- been there, done that).

More power to you!

I think I will be OK with the Spear in the IP after all it has no problems with over 80000 on it i just getting this setup because it is a good price

What I would love to know is how high can we go with a resistor (10) before the computer considers it "open" and defaults to a #5, or on OBDII, refuses to start after removing battery cables?

I got the edam setup with a new DTECH PMD for $113. Like you said, sometimes one slips through :D

I've got an extra #4 or #5 if you want one for free. PM me your adress if interested and I will send it via USPS.

When installing the PMD do I have to put a sealer or a gasket on the heat Cooler I am putting it in my bumper and it will get wet when I drive in the rain

phalfhide,
Thats an awesome deal! My 3500 stalled on base yesterday at MickeyDs. So I'm going to check into that!

That sounds way to good to be true. I can't see how a seller could sell the Dtech below cost. I need/want one and saw those auctions but that little bird keeps telling me when somehting seems to good to be true it usually is but i hope I'm wrong for you guys. I'm going to get my D Tech from Accurate Diesel. He gives a little break to DP members. I think 228$ for it.

Does anyone have any tips or pictures of pmd relocation?? I got the cooler and harness from ebay. It has been sitting on the work bench for a month, I don't know where I want to put it or how to remove the PMD. I can fix pretty much anything on my truck but when it comes to messing with the injection pump, I am pretty intimidated.

I have heard but "Don't" quote me on this as high as a # 13 not sure if obd 1 or 2 . A # 9 is a safe resistor to run and works well,higher than this usually sets off codes

Have a look at my garage, you'll get an idea for under bumper mount. I'm thinking about moving it inside bumper. If I do so, I will post pics.
By the end of the week, I will have to install one underhood (I know, i know, not the best place, but the guy doesn't want to hear anything about under bumper location).
this will be the second time I will be relocating a Dipaco that way. I will post pics too.

BTW, #9 is the higher value I know for resistor, right?

You know I got a D Tech on order right now and I was thinking about it. The D Tech from what I see so far seems to be the real thing. was wondering why you couldn't just put it back on the pump(if you don't already have a remote cooler). If it can withstand the heat like it claims, factory location should be fine..??
Don't get me wrong, mines going under the bumper but was just theorizing..

Try looking on e bay you can get the whole setup for half what you are paying

I went in your garage NICE TRUCK I like the head lights where did you get them and did you make the intake box? Is is metal or plastic

According to what they claim, yes, the Dipaco should be able to be mounted at stock location and support heat. It's a little beefer but it is told to fit.
IMO, even it is told to to resist, stock location is not the right place anyways.

Thanks :bigglasse, you're flattering me ;)
The headlights come from fleabay, a "racing guy" as a vendor. I had to do a few job on this trim to make them fitting perfectly. I'm very happy with them, especially as they are associated with HID kit. I know where is the road, even in rainy nights :D
The aibox was made by a friend of mine. It is made of stainless steel. It's a nice one, but I must confess I have been disappointed about it: the steel gather heat from underhood and turbo, and I'm pretty sure that after a while, it is hot enough sothat the advantage of an airbox has almost disappeared. I have taken it out for the moment and will insulate it with heat blankshield or made a new one in fiberglass or anything else insulated...

Yes, I was just saying #10 as an example. What I really mean is what "value resistor" can we put in the PMD for max output??? #1 = 4400 ohms and #9 = 80500 ohms (thanks Knkreb and TurbineDoc).

You KNow I saw that and was tempted but i just can't see how someone could legitematly sell it below cost and I have had great dealings with Tim.
If I have any problems with it I have no doubt he will take care of it. I ordered a #9 with it. Gotta read up on installing the resistor. I never did one.

easy, no worries. the shape of the resistor won't allow you to make any mistake.
Be careful about the pins inside the PMD plug, adjust the resistor, number facing you, and push.

I did some testing a few years ago with one of our members here as to performance changes electronically driven. The difference between a #5 and #9 resister is so small towards fuel economy or performance. The biggest difference is in the engine timing TDC from -.25 to -.50 stock and -1.50 to -1.94 hot.
Fuel economy and performance do change.

So do you have real data witch combination should be best for fuel economy?

I do not have heavy foot but my mileage is littele high.. around 15 MPG (US)

Guys your getting all wrapped around the axle over resistor, basically find one that lets the truck run, it is a calibration resistor that is used to match IP delivery to a bench test spec at test rpm, makes little if any difference at rpm not on spec setting (don't ask what rpm I just had LASIK yesterday both eyes and can't read the fine print just yet in the spec), economy is purely a function of engine health and right foot, changes to resistor inconsequential, see chart in FAQ a #5 is 0 mm(3)/1000 stroke change, 1 is (-4), 9 is (+4) over a healthy IP, if your IP is tired you won't get those changes exactly which is why you have 0-14 as possibility, but IIRC if you go above 9 you set codes

Turbin Doc is dead on. A #5 resister is fine. A TDC of around -1.50 is good too.

A TDC of around -1.50 is good too.

Probably a little less noisy than -1.94 also.

So where is this resistor located. Since I'm getting ready to change my FSD when it arrives I kind of need to know. I didn't order a new one si I guess I'll need to swap over the old one. Is this correct? Any one got any pic.s of where it's located?

matuva
04-11-2008, 09:57 PM
The resistor is inside the PMD plug. If it does not come with a new one (usually you have to purchase it separately), grab the one in the old PMD with thin pliers and re-use it.
Proceed gently when removing the old one, and you'll then put it easy inside the new one, the shape is designed a way you can't misplace the resistor.
When wife will be awaken I will ask her camera and post a pic ;)

Mine is at -1.56 and do wonder. Strong and no noise :D

Hey Matuva don't sweat it. If it's down inside the plug I'll just take a peek in there when I swap in the new one. I've seen pictures of them out but never one installed. Now I know where to look.

Well, wife is awaken, but camera doesn't work, even with a new Battery . Argh! another thing to care about...
Anyways, you will see, Yep, easy swap...
One tip : just present the resistor, don't force it inside the plug. Then push it using the male connector ot the harness (or extension), that way there's absolutely no chance you brake it.

It goes in the cavity where the connector goes to. Just in case the picture is not clear enough.
