    I need YOUR HELP !!! Lost RPM with ( RIVA RACING ECU) i have no clue what happen

    I bought a (RIVA RACING ECU) from a guy on craiglist and it seemed to be BRAND NEW SHAPE, it had never been activated before, so i called RIVA and got the CODE and had my dealer program it to my ski, i have all the other mods except (INJECTORS) in which my ski was already going 78mph with NO ECU on any giving day, and (TODAY) ski would not go over 7400 RPM........

    WHATS WRONG? its a 2007 RXP

    So does that mean you are running stock injectors with an X charger? Do you have a rrfpr? What's your base set at? Wideband? What's your AF ratio?

    These 48# injectors work well with the Riva ECUs. If you are running stock injectors, I doubt that is going to work out very well for you.

    Nope they are not!! You will not be able to cross referance what you need for the ski from any stock automobile part from autozone. Your probably not going to hurt anything yet but if you tune to get 8000+ with that ecu and you don't have the right injectors, you will smoke something and it won't be a big fat stoggie, or your buddies.
