Would this work okay?

[Apolan]

1.)
I have a MAP bluetop TVIS (bigport). Say i would buy a AFM Bluetop bigport - bottom end and head, and use my manifolds, my map sensor and my ecu on this AFM-based engine. Would this be plug and play - would this be the same now as my old engine?
All this under hypotessis that both engines have same compression ratio of 10:1.

2.)
What would happen if i did the same thing, but the pistons from the AFM-based engine were 9.4 comp-ratio. Could i Just as easily use my manifolds, my map sensor and my ecu and would this engine work with my ecu because of the lower comp-ratio, or would i loose serious power because the maps would be incorrect?

Please help, domo arigatogozaimasu!
