    Rotax 8800 to stock ECU!!

    The P-X has etec 3mm, 4" intake, Rotax 8800, 60lbs injectors, Racetech RRFRP, RIVA valvetrain...etc

    It ran like a champ but after the piston smashed the ferrera valves i decide to keep everything except the Rotax 8800 ECU and 60lbs injectors...Rotax 8800 ECU is so aggressive on pumpgas

    so will it be fine to leave recetech RRFRP plus get back stock injectors 42??

    Some ppl recommend RRFRP plus 42 inectors others recommend stock RRFRP plus 48/50 injectors with etec 3mm ON STOCK ECU

    What do u think??

    you need 48 lb injectors and the RRFPR to use that impeller.

    I though one of them is enough
