what would be the code for an ECU for a 00' B18B1 engine. Are there any aftermarket ECUs worth getting?

 

I know the OBD I generation of LS ECU's were called P75's. I don't know if that's true for ECU's after '96 or not. What year car is the swap going into? It's best to match the ECU to the year of car since your going to have to re-use your Civic wiring harness anyway. The '96-'98 cars have slightly different harnesses than the '99-'00 Civic's (sometimes called OBD IIa and OBD IIb respectively).

 

the ls swap is going into a 97 civic ex.

 

Ha ha, seems like a popular swap the last few days. Actually, hmmm. Check out this link.

If you guys were to swap ECU's it might solve both your problems. Since your car is a '97 it's OBD IIa, but a '99-'00 Integra ECU will be OBD IIb (same functions, different shaped plug) it won't plug into your stock harness. His ECU is a '97 so it should match up to your Civic harness and your ECU is a '00, it should match up to his. I've never done an OBD II swap myself, I was going to do my '98 EX but never had the funds, but to the best of my knowledge, this is right.

i dont have an ECU for this motor. so the best ECU for me to get would be from a 96-98 LS which are OBDIIa?
