Hi folks!

I've got an Isuzu Rodeo 1992 3.1l V6 which is being operated by a
122838 (ANFK) ECM (I don't know if it important but this one is
controlling a Model 220 TBI).

This ECM does have a 12 Pin GM connector with pins A, B and E
connected (other connectors are missing).

Does anybody have some information about that ECM? I'm highly
interested in the serial data stream protocol at ALDL. Also I don't
have any info at all whether or not this ECM is supporting the 160
baud or 8192 baud interface (it's my guess that it's the 160 baud I/F
because I found the pin E to drive the 160 baud line at all documents
I found on the net).

The same ECM has been widely used in GM cars (years 1988 to 1993 or
so), for example Pontiac, Chevrolet and GMC cars should have the same
ECM.

Again, does anybody have some (or lots! *s*) information about it? I
want to build a scan tool for it or find a working one but w/o any
knowlegde of the device..... you know!?

Thanks,

Volker
