6.5 diesel .xdf and adx

[newellshk]

I will be happy to provide all the supporting work including one mostly documented disassembly and four other disassemblies that I've been using for comparison. I've been cross referencing A225.ds and A226.ds along with other hacks. I can also show that I've been a professional programmer for nearly 15 years and have also done a commented disassembly and xdf for ALWB/$53 out of a 1991 Pontiac LeMans. In case anyone is curious I plan to use the LeMans throttle body setup on an air cooled vw as they are nearly the same displacement. Did you know that they were so cheap they didn't give the LeMans an IAT sensor even though the ecu and code supported it, instead they emulate it based on coolant temp if a flag is set.

Xnke - If Quadstar87 is working on a reflash routine he must be working on the ODB2 ecu's. I haven't looked into them much but seem to remember reading that they are still 68hc11 based unlike most other ODB2 GM ecu's that went to 68332. It would be interesting to see what code changes GM made over the years.

brian617 - The more bins we have available the better. I think there is a decent amount of code in these that could be removed or simplified and the space re-purposed for custom functionality. Plus the obvious benefit of comparing the calibrations between different vehicles. So far I have BNTB, BNTK, BPAA, BPBS, BPDP, and BRMM.

Very generous offer!

Cool, but I wasn't trying to make it sound like anyone's on trial. I just want to be sure that information provided backs up any claims that the definitions were not created using a pay-for definition that is restricted to the buyer only.

You already have the two I have BPAA and BNTB

Well it's going to be a few more days because I am an idiot and let Micro$oft f*ck me. I lost all but four entries in the xdf because I hadn't saved it and brilliant windows 10 decided to install updates and reboot without any confirmation.

Of course the hard work is documenting the disassembly so this really just means starting over on the tedious data entry. I will certainly remember to save periodically from now on...

I have not been so angry in a long time.

Yep, he's working on the OBD2 stuff.

Here is a work in progress xdf. I have found that it matches all bins that I have except BRMM which is odd because it does have an EC mask. Anyone have any idea why a bin with the same mask has a different calibration layout, and any good ways to detect that (or inform the tunerpro user how to easily and confidently check). Maybe the BRMM bin is from an already modified memcal done by a 3rd party vendor...

I have successfully used this xdf to modify shift points, fuel, and base timing (starting with a stock BPBS bin), so I know that the checksum etc works.

It's still fairly basic at the moment but does have a lot of the common stuff that one would want to change. If anyone has any requests please speak up and I'll do what I can. I do plan to continue to expand it so expect updates in the next few weeks. It doesn't currently have any EGR stuff except for the DTC enable flags. I also haven't yet added a way to modify the pump calibration tables (or emulate changing the resistor), but I'm not sure if that's very useful since you can change base timing and base fuel.

If someone with permission wants to copy the xdf to:

that would be cool.

Thank you!

[quadstar87]

Just focus on the $EC mask for BPAA - BXPY is the latest rev. of that code base for auto trans also. It's a waste of time to look over the other masks for light duty applications.

What kind of ideas do you have for re-organizing code? I've done some but curious what other ideas you have after seeing the disassembly you found.

Greetings from Finland!

Happy to find this great page. Thank you for it.
Just uploaded my suburbans BPAC bin. Hope it shows. It is my first time in this page ;)

This bin is from 1995 suburban. No EGR's from factory.
Hex format looks much like BPDP bin.


I have already moded the turbo wastegate to spring loaded one.
I read ECM data with GMTDScan.
And have Dataman programmer + some flash chips.
Can't wait to be able to tune harder shifting, less timing & more fuel.
But still have some problems with TunerPro.

Hope I can contribute something to this awesome page :)
Thanx

With some of the tables, the graphs don't work?

[newellshk]

Probably because one or another axis label isn't filled in. I've been slow doing the axis because I want to ensure they are accurate. I'll try to get those finished soon but please tell me if there are any specific ones that you need and i'll prioritize them.

In the meantime you could fill them in with a simple sequence (0,1,2...) and the graphs should work.

hi i was wondering if you still any of the files for 1995 6.5 diesel to get into the pcm. im running tunerpro rt.

[updatelee]

Stevtatt07: Sorry I replied to you on another forum and pointed you to this thread, didnt realize you were already here. My mistake.

What can we help you with? the xdf you need is in the post above your's, the BPAA bin? you can get it from dripspeed or read your own, mine wasnt a BPAA so I just grabbed it from dripspeed, its a good bin and works.

[Stevtatt07]

oh ok im not sure how i missed that thank you.

[yoheer]

I'm searching for BIN file

4056
BKWB
3342

I've found 6.5 diesel bin files collection somewhere, but i've lost it :(
Can anybody help me?
PCM 16183977

Can I use BPDP instead of mine bin? (Blazer '94 2dr)
