I have a 1992 Integra RS with the stock PR4 ECU. I need a chipped ECU for a higher rev limiter (see sig) but the shop i'm doing business with, don't have any program for the PR4, they only have P75 programs, my question is simple, will the P75 fit? (since it's OBD1 and it's from non vtec integras.)

thanks in advance.
