Many years ago I went through the attached file to create a larger $32B XDF for myself to use in TunerPro with my 1987 Coupe. It took a while but was a fun learning experience while getting it correct.
Has anyone come across a similar file for $F0? I'd like to learn more on how some of the variables interact and see if there's anything worth adding not already in the definition. |

Can't vouch for whether these are any good, but found a pile of them here, looks like it may be what you're after?:
https://www.tunerpro.net/downloadBinDefs.htm At very least, maybe a good start.

Thank you but not quite. ![]() The stuff I'm looking for would be the original assembly program GM used for the ECM itself, sort of like the file I attached for 32B in the first post. Those can be read to determine the address locations of other switches, scalers, and tables that may not already in in the XDF or just to better understand how they interact with each other. It's a little nerdy to want to read them, but it's the kind of thing I enjoy combing through and building a few more wrinkles in my brain. ![]()

Rgr, thanks. Not familiar with TunerPro, so wasn't really sure what I was looking at. I dig that kind of stuff myself though, wanted to dig into it a bit. Not familiar with how GM did its software engineering back in the day, but I imagine they did not provide assembly source for their ECMs to just anyone who asked for it. Interesting reverse engineering problem.

Rgr. I was poking around last week for a motorola chip diassembler, looks there are a few running around of unknown (to me anyway) quality, and IDA may be able to do it in the paid version, still looking into that.

if that's what you are asking.

Many many years ago I made a complete, fully commented disassembly of BFXB, and BMCB. Had the others partially complete but moved on to other things. Had full access to the source code to add, delete, routines and reassemble. It worked, I added closed loop lambda control at one point. I had a lot more free time in my 30s I guess... LOL
