B]96 OBD2 Ls in 95 OBD1 Civic Ex need ECU[/B] I have a 95 Civic EX with a motor swap from a 96 Integra Ls. My motor is OBD2. Car runs great. I think it could run better. I'm running a P06 ecu from a Civic Dx. Does anyone know of the proper ecu to use that will work with my motor. Do I need a P72, P74, or P75. I have a P75 from a 96 ls. I know its OBD2 and the harnness wont plug up to it. Is there a 92 to 95 P75?

 

The P75 comes in both OBD1 and OBD2 and is the correct ECU for the LS.
