I'm looking for any information that I can find on this pcm I have a 1998
Z28 Camaro that I would like to stroke and supercharge over the winter but
in order to tune It I would have to make some pcm changes.

My understanding of the ODBII system on my Ls1 is limited. I have a pretty
good grasp of what is going on but would like to find a good book to
describe my system as a whole. 

What I have found so far
CPU = Motorola MC68332 160 pin unit not found on public documentation from
Motorola
ROM = Intel 4 Mbit flash ROM

I have a pretty good understanding of computers and have programmed in
assemble before. But I am looking for information of the system as a whole.
I have heard that there is a network in the system that every thing ties too
? Is this true ? If so what is the protocol. How can you pull the binary
from the ROM through the ALDL/OBDII port ? If anyone can help that would be
great or at least point me in the right direction. I am all for a FREEWARE
or GPL OBDII scanner/editor. Well that's enough for now. Thanks in advance.
