Re: Is there a $F0 source/assembly file anywhere?
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

For what it's worth it has been recommended I give Ghidra (https://ghidra-sre.org/) a try for disassembly. The NSA created it.... so who knows what else it'll install on my machine. :mrgreen:

I found an old presentation I did at the Gathering in 2004. Attached.

Re: Is there a $F0 source/assembly file anywhere?
If I remember, the "ANHT" hac was more closely related to the LT5 code at the time. It almost seemed like the various operating code sections were pulled from a menu and inserted into whatever calibration they needed to create at the time. All the LT5 calibrations are similar, but you can tell over time where they added some tweaks and minor functionality here and there. The BMCB version strikes me as the most advanced. Makes sense since it was among the final releases.
Here's a snippet of the BFXB code, which determines the target air-fuel ratio in open loop, and then applies the richest of the calculated ratios to determine the final ratio. Code:

Interesting stuff going on in those old ECUs. More complicated than I realized.
