Let me just get this one last thing straight. I can put a 0bd1 p75 5-speed ECU in my car correct? Since the obd1's only have 1 o2 sensor (right?) then that should get rid of the one code.

But my main q is a obd1 ecu cant do more harm can it? I know i wont pass emissions but i dont have to worry about that for another 9-10 months anyway.
