    riva ecu

    I have the following mods and was wondering what extra would i need to run a riva ecu, i already have #50's

    x charger
    42's
    free flow
    intake grate
    4' kanaflex
    15/20

    and what kind of speed would this bring me if i added the ecu.

    Just need valvetrain upgrade. Then prob have to de-pitch your prob to get RPM up and see the gains. R88

    If you plan on running an IC then you will need a RRFPR..

    with the riva ecu you wont need the rrfpr..with just the x charger..

    the riva ecu willl handle 14 psi on the 50s...BTW which i have a set with 7 hours on them FOR SALE if anyone needs them ...

    my boat ran 81.4 with a x charger and riva ecu..you will see 12 to 13 psi
    see sig...

    you can use the riva ecu with a stock intercooler if you like with your set-up... i have used this same set-up on my buddy's 07 rxp with speeds of 81+mph.

    i have found that the riva ecu will pick up a sold 3-4mph on any ski with just about any supercharger and set-up.... as long as your prop is pitched correctly. for your best performance you rpm will need to be about 8580 to 8620.

    i have built lot's of 80+mph skis using the stock intercooler.
