    RIVA ECU with Rude Fuel Controller

    Since several prominent member's testing has revealed the B-kit/Rude charger is too lean for the Riva ECU and 50# injectors, would it be wise to drop in 55s or something slightly bigger and use a Rude fuel contoller to take away the necessary amount of fuel? If anyone has done this, any chance you'll share the fuel map and parameters?

    I had no problems running the Rude with the Riva ECU and 50s. No sign of damage to the manifold bell.

    Me either so far, but several people are getting uncomfortable AFR numbers with the combo and I'd like to play it safe on such an expensive and fragile ski.

    A few have switched to 55 lb injectors which dropped the AFR. I think BDNJ reported that in cold weather the 50s ran 12.8 and the 55s ran 12.1 AFR. No issues other than a slightly jumpy idle.

    That is the same info that I was told Vern, in colder weather just drop on the 55s. But I have not tried it in my ski.
