    ECU is not programmed correctly. Call Riva and get them to give you the proper BUDS info so you can take it to your dealer and have them fix it.

    BOAT SPEED ALGHORITHM
    M-Boat = 0.3281
    B-Boat = -105

    Those need changed... I am not sure what they should be... If you can call Bubba at Riva and he can tell you what they should be set to. Basically they are like multipliers or something like that.

    Exactly what I did on my X boat. Speedo now works past 70 but what sucks is you lose the preset trim settings when upgrading to RIVA ECU on the X boats.

    See attachment for pic for RXP and RXT algorithms.

    Thanks Dude


    the volume should be :

    RXT :
    M-Boat = .3359
    B-Boat = 0

    RXP :
    M-Boat = .3164
    B-Boat = 0
