    Injector questions

    What is the largest injector that seadoo has ever offered in a RXP--RXP-X??
    Someone said that the newer I control skis have 48's but they will not work on a non I control ski correct?
    Until the IJSBA votes next week I am stuck using only stock injectors, I can go up and down in years but it has to be RXP--RXP-X models only,
    How hard would it be to run the I control 48's in a 06 RXP??

    There you go another dumb rule
    You can’t use different injectors but you can modify the stock ones
    So if you can modify them, what is the difference?
    and if you cant mofify them how could they check them at a race...
    any 14mm X 48mm o-ring injector with a ev1 conector will work in your ski
    or you can use a adaptor plug to go from the new bosch ecu uscar plug to the old Siemens ecu ev1 plug
    but every injector has differant "lag" times
    you need to find a injector with very similar olms and latencies for the best match to your ecu

    You can run a FPR though legally.

    Adding a rrfpr will require a full retune.

    Talk to these guys. The 42 lb version is below. I bet they can cross referance the 50 and 60 lb version. The more common application for the injectors is in turbocharged Volvo motors.

    I am running 42's now with the ET-137 wheel and the Rotax racing ecu, it is getting lean at 8500 rpms,
    I was thinking that using 48's would solve my problem, I have my RRFPR dialed up pretty high, with the reference line hooked up,
    but for now it, has to be a seadoo stock brand injector,
    does the I control 48 injector have different holes also? or is it just the wiring connector?
