    RR stock class ecu 8350 rpm
    RR racing class ecu 8650 rpm (you need retainers)
    You can run both with 42 injectors & regulator
    depends on your set up & the supercharger you gona use.
    you can use 48 & 50s also!!!

    If you are looking at a 2004 ski the RR racing ECU has a limit of 8600 if I remember correctly, not 8650.
    Either way, both ECUs hit harder than stock.

    Yes any key will work on the
    RR ECU. The knock sensor stays hooked
    Up, but without the harness adapter.
    They run more timing for racing.

    I have one I'm about to use, with 50# injectors and a mini-rude. Any advice for base pressure on the rrfpr?
