Hey all! I was wondering if theres anything one can do with a laptop and a 1992 Camaro? Its a v8, I believe L03, TBI I have no idea about anything on the computer in that thing... I pretty much figured out its not ODB2 compartible...what is it then, if any, and have anyone done any usefull "experiments" in hacking into the car?

Lots of stuff for that vehicle/ECM available. More then can imagine. As for a scan tool data loger there is WinALDL. A free piece of great software that runs on a PC or laptop. There are quite a few people here on TGO using WinALDL too.

There is a commented listing of source code available for that ECM (a hac). Your ECM will be a 1228746 or '8746 for short. The hac can be found on the www.diy-efi.org site in the GMECM section under the ECMs and other info link.

Then once you get going on this and want to re-progrom the ECM there is information (and patches!) available for that.

Check out Trax's writeup at this link first. May be confusing but it's a start.

To start off get WinALDL (should be a link to it in Trax's article), and scan/data log for a while.
