Interesting that the two different pumps/tunes seem to be playing nice with each other when common wisdom has said for all these years that the two '94 3500HD pumps weren't interchangeable. Could it be that the oddball was rebuilt at some time with the other's parts you can use the different...

Not yet Been stewing about this the last couple of days trying to figure out how this came about, well figured it out the night before last. I DID NOT DEVELOPE THESE FILES. I claim nothing on these files, If I did my name would have been put on them as the author. These files have been posted...

i'm glad the file is working , was gonna start scratching my head if it didn't.

I actually did post a disassembly of a modified BJAX a few pages back. It's all there just not all labeled. Give me some time and I will make some new files. It is a long time consuming process.

thanks

one mistake is calibration ID is 16 bit and start address is $4000, not a big deal usually.I can change it or Dripspeed can. I'll look for more, and add a few things I forgot later.

Buddy is absolutely correct. That was my fault.Just got to the code section in the bin and it's not all there. I was looking for certain code and non accessed ram to make sure it was there. Never had the opportunity to look at a standard trans bin for the 6.5. But have with a gas engine and it...

chip orientation is important.sometimes hard to see which end is which.

I believe ECB xdf has Ignore Checksum written in to it...under scalars. It does, just checked. I personnaly have had that problem once, reburned the chip and it worked ok than, I think the checksum didn't update fast enough before I burned the chip.

ok if that works for him then i'll add that to the XDF

that sounds like the checksum problem. Some tranny files will be in there because they deal with the baro being set to high altitude and some other stuff, but I can't comment to much on that cause I haven't hacked the file that far yet. That's still alot of work, given time though i will. Try...

The bin I have for him is correct at 32KB, smaller file because he has standard tranny. Bins with automatic trannys are 64KB. Does the Glow plug light cycle like should? If not there usually is problem with the burn, or the checksum is wrong. tuner Pro has a checksum calculator in, that usually...

Here's a little tip for those of you that want to learn to tune yourself. First question your gonna ask is, which file is for my truck. Well here goes... grab all the posted XDFs and download them, put in Bin definition folder in tuner pro. open tuner pro and your bin file, pick an XDF, start...

that's an easy answer. Those are $4004, $4005= platform Id, $4006, $4007= checksum. They change whenever you make a change to the program.

If you would post or pm me the files, or tell me what sections I'll take alook and see what it references to in my spare time. It would be faster adding to the Original XDF than building new ones. It's alot of work..

The page for what each line of hex is is the disassembly. I posted one of a modded GM updated bin. I can post that Bin too if you like, It might help with what you're looking for.

did you do a comparison between 2 files? if you did they need to be the same type of file to get the differences, A stock file compared to a mod file, or comparing the different addressess? The firmware is mapped to about 92mm3 but capped at 80mm3 I believe. There's room to rewrite and get...

File removed per OP request Yeah I have one that is almost finished, ran into a snag , got confused and than aggrevated because of some tables, walked away from it. I can see the reference pointers to a couple of tables that point to 3 tables that are the same and 4 more that I am confused...

yep that file is correct

I just noticed that you also have my ADX posted. Cool, It's somewhat finished, there is a lot of doubles stuff in there that has to be taken out.( I was trying to figure out how to combine 225/226 together cause thats how GM did it ) It does work, well what I tested anyhow. To Data log you have...
