I'm doing a top swap on my 97 SE 3.8 from a 97 GTP. I'm also swapping the transmission and the wiring harness. So essentially, except for the block, I would have a GTP under the hood. I'm doing a top swap instead of an engine swap for the experience and to make sure the gaskets are all sound. So, are there things in the PCM that deal with the engine block(compression ratio, etc) that need to be set or would I be just fine using the stock GTP PCM?
