Everything you ever wanted to know about the GM ECM & more found here.  These are probably the most knowledgable guys out there (next to the general, but he's not telling), when it comes to the GM ECM & GM EFI in general.  I have learned more from these gents than I ought to admit.
WWW.thirdgen.org
There is a ton of information on this site about 3rd gen camaros & all of the things that make them great.  There is also a ton of great information on EFI & tuning your CPU (yes it can be done, under adult supervision), & making your car run great no matter what modifications you have done.
