Re: Jdm p2t vs usdm p2t ecu (Project.Jdm)
I don't think that's the truth on OBD2 ecu's, but partially true on OBD1 ecu's. Is there an OBD2B P2T ecu? I'm just curious about that....

Unplug your secondary oxygen sensor, located in the cat convertor.
If the check engine light comes on for it within a day of driving, congrats - you have a USDM ECU.
If you drive that way for days on end with no check engine light, congrats - you have a JDM ECU.
The JDM ECU lacks a few extra inputs that our OBD2 ECU USDM ECU looks for, and the secondary o2 sensor is among those things.
