    they are 99% the same thing.
    but the pr3 will take better to chipping and re-programming.... and is easier to find and will probably be cheaper

    i do not think there is a pr3 usdm ecu. Just a jdm one coming out of the integra xsi. But please correct me if i am wrong.

    no USDM PR3 - JDM + EDM only.
