I Just did an auto to manual swap on my crx and i swapped in a ZC while i was at it. Well when i use the ZC ecu i get a code 13, but if i use the crx si ecu i dont get any codes, or if i use a 90 integ ecu i dont either, well my question is this is there any wiring difference between the USDM Si ecu and the ZC ecu? or is this ecu just defective?
