Hia people
I didn’t see thread on this yet and it’d be something useful to have as a reference when swapping out ecus and/or motors. While many ecu’s are interchangeable, obd I and obd II are different as far running open loop if extra emission sensors are not present - not sure about s13 vs s14.
So I’ll start this off…
1995 240sx / s14 (zenki) ECU (OBD I)
Manual - ecu code 3C
Automatic - ecu code 3Q
