	M3.2-M3.8-M5.4-M5.9-Binary-to-asm-Project « on: February 24, 2026, 07:20:22 AM »

Hi
I´ve done some more work on the old 87C196KR. I made a parser to generate asm files from a binary of the M3.2, M3.8, M5.4, M5.9.
Project is with sybmols to Jumps and Calls so just make changes and hit compile, rl96 and compiler script will do the magic for segment references.
Segment Jumps are detected but backjumps can be wrong. Data parsing is not done by now.
Checksums are also not done. Any information about checksum calculation on these old ecus would be nice.

If you are broke or expecting free handouts DO NOT message me. I'll probably put you on blast if you do.

Would be REALLY nice if someone could make it speed density instead of MAF based.

it´s a pain in the ass to find original MAF sensor nowdays

I just put one HFM5, calibrate it, fine tune with 2-3 files and its done.

Hi Junior, maybe I am dreaming but add wideband O2 support to that speed density idea and you have a nice, simple and robust ECU that could control big projects too.

Did it sometimes in the past, but even those MAF are getting difficult do find, and cost are rising in my country

Don´t think there is the necessary HW on those to run a Wideband sensor

5V signal from a WB controller going into some ECU input.
