What else do you need it to run? ECU stands for Engine Control Unit. I guess I am confused as what else you need it to do.

 

i need it to run the rest of the car as in the dash and ignition... i have the harness to run the motor.

 

i still have the other car (wrecked 00 si) do i need to get anything else off of it to get it to work??

 

your doing it the hard way, convert it to obd1(preferred) or obd0

x2, just look up Rywire since they make it soo easy to do this kind of stuff if you aren't good with wiring (hince why you posted this question).

I too say go OBD1, much easier and benificial for power gains.

I'm guessing you are planning to use the wire harness from the 00 Civic Si, correct? Dont.

Use the existing wire harness off of your old motor. Modify it to fit the B16 and then you'll need to swap the connectors at the ECU to OBD2 connectors. You'll also need to run several new wires if you plan to run the OBD2 ECU and add some emissions components to your car. It can be done, I've done it before, but realisitcally, convert to OBD1 and save yourself some time.

 

obd2 ecu also runs a tank sensor that u cannot use in a 90 hatch.

convert to 4 injector if u arent already, and preferably use a obd1 p30 ecu
