Computer compatibility
you can run a 2004 ls1 engine on a 2001 ls1 pcm all day long. The pcms are different though, and you cannot use a 2004 gto pcm in a 2001 f-body wiring harness, without modificatons.

Are the pcm and pcms all in the same unit? Lets say I get the correct computer to do the swap, all my gauges and everything will still work properly?
You cannot put a 2004 GTO computer into a 2001 f-body wiring harness, the red plug of the f-car wiring harness does not mate with the green connector of the GTO pcm.
