2000 civic si with jdm b18c swap. I am running OBD1 sensors on the motor with my stock obd2 00 si ecu. which ecu do i need to put in there?? i just purchased a 2001 teg stock ecu and the car will turn on and crank but not start up. help me this is annoying!!!

 

i don't know the exact part number of the ecu, but you need an obd2 (96-01) gsr ecu

 

How do you have it set up exactly? OBD2 ecu?

you also need an OBD2 distributor to make it work. You're better off with an OBD1 ecu and the conversion harness if you're motor is ODB1.

Or you can just get a distributor for the ECU you have.

OBD2 ecus will not work with ODB1 distributors.
