so basically i picked up a 99 ek coupe with a b20b4 in it the motor is obd2a and the ecu is obd2b. i found a obd2a p2e ecu could i just use that one and it will work? and what kind of harness would i need or would it just be easier to get a jumper harness?

 

I guess using a d16 1.6 liter ecu to run a 2.0 liter b20 engine would suffice huh, lets see how long your motor will last
