Duramax ECM tuning Software!

Guys,

I have been working with this company as a Beta Tester for over a year now using their software to tune LS-1 powered Corvettes Camaros and Trucks. They are now turning their attention to the Duramax world. The Duramax stuff is in it's infancy right now and they are looking for Beta Testers. http://www.efilive.com/forum/viewtopic.php?t=2419

I used the software tonight to make some minor changes to my stock ECM.

Of course SoCal Diesel is a distributor of this software, development is continuing and working copies are expected for delivery some time in December.

$699.00 gives you license to tune two vehicles. So team up with a friend and save some $$$$$$$$$$$$

$99.00 for each additional vehicle after that up to 25.

For those that are unfamiliar with the software, it will allow you to:

1) Data log and store runs just as you would with a Tech 2.
2) Clear codes.
3) Write your own tunes........if you dare. :D

Currently working with only LB7, LLY to follow and then perhaps control of the Allison TCM at a later date.

I'll save people the time of asking- When will you have them?

The software/hardware can be purchsed today and you can tune LS-1 gas motors. Updated Diesel software version scheduled for release the first part of December.

You KNOW I'm going to want one! :D

Will the current version do any datalogging on the Dmax?

Yes it will, but not all the PID's (yet), last count there was over 70 parameters you could monitor on a Duramax, it will log everything the ECM can tell you by release date, which will probably be closer to 100 parameters.

Guy when he orders it, don't let him forget we need 3 licenses so we can do the Meanie also :D

If the software is under development still, it would be nice to be able to disable certain DTC functions that affect performance. Some of the Dmax errors cripple the engine operation and make it hazardous to drive:

Overboost
Underboost (LLY)
Low fuel rail pressure
EGR codes

You can disable ANY DTC, but you can also alter the window of failure before the DTC will set. See the screen shot in my main post under the title "Broaden the error tolerance for common fault codes" for the under/over boost failure parameters.

Ross

That'll work! :D

Cool, So the current tool could be used to elimnate some DTC (ie 401 and 404)and broaden the specs on others?(1093)

I guess I can stop looking for a TECH II on E-Bay now........:D

You know I have to have one.........;)

Thanks for introducing this product..........:)

BTW these screen shots look like the same tuning software Parris used to tune his Turbo/6.0 litre truck with.......

The way EFILive has worked from day one with the LS1 tuner is whenever requests from users come up we usually implement the changes very fast.
So for your example above, the answer is no, we cannot do anything more than turn those codes off at the moment.....but that might have to change before release date :)

THIS is awesome! :ro)

Will we be able to share tunes? I want one for every day of the week. :D

I got dibs on the first McRat tune! ):h

:muahaha:

Share tunes, yes for sure, but who's going to share the first 11 second tune :jawdrop:
A tune for everyday of the week, na, one for every set of lights ):h :driver:

Guy when he orders it, don't let him forget we need 3 licenses so we can do the Meanie also :D

The "Personal" version ($699.00) includes the hardware/software and 2 licenses.

The "Commercial" version ($849.00) includes the above and two addtional licenses.

The "Workshop" version ($6,980) has unlimited licensing. :D

Also of note is the fact that you can data log or download code from any supported vehicle. Your license is only locked when you "upload". :D :D

Kat,

At one time there was some trade in value for LS-1 Edit. I'll check and see if that is still the case. You don't know anyone with one of those laying around not being used do you?

THIS is awesome! :ro)

:muahaha:

Someone distract McRat, I'll pull the fuse :D and you can download his LLY code. ):h

Although remember, we are in Beta right now with LB7. LLY soon to follow.

First salad, then soup, now the MAIN COURSE!! :D

New meaning to "Co-Pliot", you would need one full time just to change all the tunes!):h

this is down right scary.... i want one bad but dad doesn't have the tranny to play.

It should only take a couple of minutes to swap tunes. When we were running the Vette "stock", I had about 6 tunes I would use depending on conditions. You can name them very explictly, "Cold_air_7100rpm_100octane_24deg_89o2.xxx" or "summer_6900rpm_pumpgas_22deg_92o2.xxx".

The subject has come up whether you can do serious damage editing your own PCM. While the simple answer is yes, it bears more discussion. With gas engines, you can destroy them with too much timing, too lean of mixture, and too many RPM. The diesels are more forgiving as they do not have mixture requirements, and our RPM is currently controlled by the TCM. If you watch your boost gauge and your pyro, the only thing to seriously worry about is the timing. And even then, our forged pistons and beefy lower ends will probably take a lot more abuse than lightweight cast pistons in a gasser.

While nobody knows for sure, I'd say tuning the Duramax will be safer.

The "Personal" version ($699.00) includes the hardware/software and 2 licenses.

The "Commercial" version ($849.00) includes the above and two addtional licenses. Total of 4..........Ralph?

DOH!! Yes, we will need 4 :D

Let's see I think I have A-tap, EASE, or yes and an LS1.edit sitting around:cool:

I see Ross has started his own thread.

Lets just close this one and keep everything focused in one thread.

I'll let Ross take it from here.

Hello everyone. I ran across this message on the Full Size Chevy forum tonight. I recently visited Jesse's place in Warsaw, IN and had him custom tune my Z71 Tahoe. What a huge difference. Anyway, he seems to have come up with a way to make DMax's scream. FYI

The following is Jesse's message in FSC.

Hi guys. The duramax computer is finally hacked! I can now offer you guys completly custom Duramax computer programming. There are Hundreds of things i can change, and i have several hp ratings that you can choose. THERE IS NO LIMIT TO WHAT i can do with them horsepower wise. But you will break things if you go to HIGH on power ratings of coarse.. But i can do the same power levels that any handheld could ever do, and they are perfectly safe. I can change tire sizes, idle speeds, All fuel tables, Glow plugs, Maf tables, ect.. even boost controller stuff..

Mail in pcm programming, and core service is available for them already... Let the fun begin...

Call or email me for details. 574-267-3630

So how many HP did it make on your truck?

sure the capabilities are there but who wants to be the first 200 hp + guinie pig with a new tune!!

I'm confused, I thought the software wasn't going to be released until December:confuzeld

OK, after a bit more reading, this Jesse Bubb has a EFILive beta license and is selling tunes.

McRatt are you ready for his 350 hp lly tune:lol:

Jesse and I are both Beta testers and resellers of EFI Live software.

Jesse is an awesome tuner in the gas world. :ro)

Remember, the software as it is available today is the finest LS-1 tuning software that I have ever seen. We are in Beta right now with the LB7 stuff.

You can certainly purchase the hardware/software today and tune any LS-1 style engine.

The LB7 Diesel portion of the software will be avaialble for public download/release in the beginning of December.

Those that buy before the public release can simply download the update for diesels as soon as it is made public.

Hope this helps. :D

Will it remove the speed limiter and RPM limiter on 2001 LB7s?

What hardware interfaces (cables, connectors etc) are needed? I assume this in intended to be installed and used from a laptop plugged into the ECM jack in the cab?

I haven't tested an 01 yet with the beta stuff I have. But I will try one and report back.

You are correct about how it hooks into the laptop. Included are cables, software and a block box interface.

Tonight I modifed my stock tune and corrected for tire size. Disabled the intake air heater circuit. Changed the idle by +50 rpm (just to smooth it a little) and disabled the EGR circuit.

Of course this was all for testing purposes for the software. I would never drive it with any emissions equipment disabled. :D

Keep rubbing it in. I know there are a lot of us LLY guys that are very anxious to get our hands on this. Please won't someone think of the LLY guys! :D

Can you (does it) retain your stock ECM settings for a quick return when needed? Similiar to what the downloaders have done

If I understand it correctly you download the stock tune into the the PC so that you can change the tables. Once you have the copy then all you do is keep saving the files.

I wonder if VIN# reprogram is part of that too ????

Very Interesting.......:cool:

Proceedure is as follows.
Read the ECM, save the file to the PC as your 'return to stock' file.
Then go in and change anything you want as many times as you want.
Whenever you need to return it to stock, just load up your original file and program that in.
You could even develop up a tune that makes very little power for those occasions like leaving the truck somewhere that you don't trust.

VIN changing can be done......that won't give you an extra license though :naughty:

We can do the speed limiter on the 2001, RPM not yet, still trying to figure out what GM are doing there.

Cheers,
Ross

I was wondering about the VIN# as I am sure members will be swapping tunes and if my ECM has ********# for a VIN# then they need to reprogram their VIN# into the tune so that it matches the BCM.

Anyway $99 for each additional license cost is good, so I don't think many will complain.

:D
.
.
BTW I noticed that transmission shift point values are available on the Speedo Correct page, but are greyed out. Will we be able to change shift points/rpm points or is it a MPH ???

Without going into boring detail of the ECM structure, the VIN is untouched during programming, it is irrelevant as far as the software is concerned, what we do though is not allow calibrations from different years to be programmed into a non compatible ECM's.
As an example, if you have a 2001 and you get a file from a 2003 sent to you, then we will not let you program that in, if you did then your truck would be dead.
It's not the end of the world though, you can cut and paste entire maps between files of different years (assuming the maps are the same structure).
Having said that, we are just finishing off the option to do a complete re-write of the ECM, that would allow you to update the ECM just like the dealer would do.
As an example, go to - http://calid.gm.com
1 - Type in your VIN, and hit submit.
2 - Select PCM/VCM & Normal - Next
3 - Click on the Tab that says "Operating System"

You can now see all the GM updates for your truck, if you got the updated file off someone you could update the ECM in your truck yourself.

That is an LS1 only feature right now, because the LS1 computer controls the trans as well we have the option to automatically adjust the shift speeds (MPH) after a diff ratio change. If we ever figure out the Allison computer we would try to do something similar.

Cheers,
Ross

Any chance this software will fix the Allison shifting?

Not yet, but we are looking into doing something.

I think I need some clarification.....
If I remember correctly, the 2001 software is different, the 2002-2003 software is the same, and then the 2004 is different as well. Have you guys dug enough to tell me if a 2003 ecm will run a 2002 truck,(although it will set codes and some functions will not work in the truck) can you take the file from the 2003 and put it in....and what exactly would you have to make that happen...other than changing the VIN?

Thanks,
George

George,

You are correct with your software breakdown.
The important thing to check when flashing between different years is the PCM HDW Number, Or PCM Hardware number. This is shown on the sticker on the PCM's case (see pic), if that matches bewteen applications then the PCM will at least accept and run the software O.K.
I have not gone in deep enough to know what happens between year models, most changes along those lines are to do with serial data messages to the instrument cluster etc. Just an example only, an early model may have a gauge connected directly to a coolant temp sender, whereas a later model might use a serial data messge from the PCM to the cluster to get the coolant temp.
But, if you check on GM CalID then you can see what would be compatible with your vehicle.

Pepperidge, this is the only mod I've done to this truck and I love it!!! Lynn

This stuff has me all confused????? Can this tune shift on the fly, and how does it compare to the tts extreme? i have many more questions but lets start there.

In comparing to another tune it really doesn't. You are creating your own tune. If you can create a tuning setup that makes your Dmax out perform a TTS Extreme tuned Dmax, then yes it'll outperform. IF, however, you can not create a tune that is comparable or better, then you will not out perform a TTS Extreme tuned truck. It is all up to the tune YOU develop OR pay some one to develop. It simply allows the user to do what all these other companies do, make performance tunes. You have to know what parameters to set and what to set them at to optimize your performance.

As for the switching on the fly, it is my understanding from the reading that you will have NOT be abel to. Create a tune, download it, and go. If you want to switch, I THINK you have to redownload a new tune.


Some one please correct me if I have understood all of this wrong.

If you want to switch the tune you just re-edit the one that is saved on your laptop and upload the new modified tune
