Dissasembly of a simple Motronic bin

Postby festy » Tue Jul 16, 2013 7:26 pm

Here is a listing of one of the most basic Motronic bins I've seen.
It's for an Alfa Romeo 75 2.0 Twinspark, ECU 0.261.200.108.
This bin lacks a lot of features compared to 'normal' TS bins, this one doesn't even have closed loop :shock:
But it's simplicity makes it a good place to start learning these systems ;)

I've labelled most of the interesting memory locations, and named/commented a couple of the more important routines like the table lookup functions etc.
This asm file compiles with the free asem-51 tool.

Hello

Thanks for the .asm file also.
I have compiled it with the asem-51 tool. My output is this 1267355230.bin file:

ASM, you can load 1267355230.bin in IDAPro then.
And you can open 1267355230.asm with wordpad or similar.
