Ok here its is. i read the art about ecu's. my question is can i save some cash in using my p28(?) compter from my 99 civic coupe, when i swap a gsr B18c1jdm motor in it. Look my car is obd1 and the gsr would be obd2 right. So if i understand correctly obd1 is a better ecu and i would need to add some wires? for secondies?knock sensor.etc. Can someone explain this to me please cause i'm really confused.?? :unsure:
