I'm looking to do the swap in an 89 Civic LX. My concern with the transmission and ECU is because the LX has a PM5 ECU, as well as DPFI. After conversion to MPFI, I'll need a new ECU. If i'm guessing correctly, I'll need a PM6, PM7, or PG7 ECU because of the LX wiring harness, that comes from a car that had an automatic transmission to be compatible with my transmission.
