what years are alike?

PCM wise, what years are about the same?

its-
94-95
96-97
98
99-00
01-02
then how about the ls1 and ls2 GTO?

how different are the PCM's between them all?

any insight would be VERY helpful

Are you referring to pin locations on the PCM harness, specifically?

I reflashed my 2000 O.S. to a 2002 using EFILive. I believe you can do that to a 99 as well. 2003's and above need a different PCM altogether I'm pretty sure.

99-00 and 01-02 are the same ECM, but the parameters in the program are different. You can rewrite a 99 to an 02 though. Pin wise they are the same, the 99-02.
