I have a pic request for both of these ecu's together. How could i tell if my Ecu is a JDM or not. I think it is cause the motor is JDM and it was a complete swap but the ecu doesnt look like it. TIA

Edit* Sweet! Just hit 500 post

JDM ECU is half the size of the USDM OBDI ecus.
looking at the barcode you can usually tell if the code reads:
37820-P72-000 or 001 or N01 or J00 and so on. Means JDM ecu
while USDM Ecus are 37820-p72-A00 or C00 or alike .


thanks to katman again, visual aid.

Question though... I've had an OBD-II USDM P72, and a OBD-I P72 JDM ECU currently (only one I could find at the time)... is there any program difference, besides the OBD garbage (say the difference between a JDM and a USDM OBD-I ECU).

can you run a JDM p72 on a USDM b18c motor with no problems?? if so are there any advantages??
