Intro

[Tom Hussey]

Hi,

I also have a great interest in OBDII. I have been disassembling my PCM
('97 Camaro Z28) with some success. GM used a MC68HC11F1 series
processor and a MC68HC58 controller for J1850 on this car. I have much
of the code for the PCM disassembled and am quite interested if you have
a list of the "manufacturer specific" PIDs. Those are the ones that go
up from 1000. Any info on OBD would be of interest. 
I hope this list doesn't center too much on one specific P/ECM but goes
more into general details of wider interest.
