I own a 1989 GTA with a 5.0 liter TPI and have decided to become experinced with engine tuning and possibly later chip burning. To start could some one recommend a good engine scanner and maybe some articles or books on scanning and tuning these engines. I have a timing light and a basic understanding of how engines work. Thanks.

 

currently I use a laptop and datalogging software. Before I went down this road though I was considering the AutoXray .
Heres a article that turned up doing a quick search. Diagnosing The GM TPI

 

There are several free scan tools that use a laptop. Here are a couple of links that will help:

There is also the TunerPro package that also scans.

Thanks everyone. This should get me started.
