Hacking/tuning the jeep ecm

[JeepsAndGuns]

The link I posted will show you where to look for the microprocessor, then get the numbers/letters off the top of the chip.http://starparts.chrysler.com/starli...n/Electric.pdf

Ok, back home. I pulled the top off the spare ecm I have, and it looks a little diffrent on the inside than the one in that link, but I think I got the correct numbers.
The numbers goes as follows:

SC80571VFN
672T02
C96N
ZQESI9312

Also the eprom is a 27C256-20

The SC80571VFN is a Motorola processor. I'm not familiar with it, but there is info out there about them.

The C96N is also a Motorola Processor which also has documentation.

There are also a few tools out there if you are serious about making your own hack. This IDE should work for the C96N, and has colored syntax for opcodes.

I do a lot of stuff with the turbo Mopar ECU's. All of the SBEC's and SBECII's use a 68HC11A series processor.

I have many of the Jeep bins already and have kind of started dis-assembling the code. But, I need to get back into it. I had a '95 GC last year that I had intended to do a cal for, but just didn't get back to the code. Too busy with other projects. Anyway, the GC was too rusty for me to use as a project (I know, big shock, a rusty Jeep in Michigan). But, I'm still interested in hacking the code. I'd be happy to help as I find stuff...
