    Riva ECU

    Anyone have any info on this yet? Is it any good? Can it be run with les b kit, nills supercharger, or rotax, or is it only for the riva kit? Is it adjustable?

    Mike... to run anything like the B kit or Nilacharger... ur gonna need a fuel controller. 13psi + with serious air flow.... none of these ECUs are equipped for that kind of power.

    the riva ECU alone wont cut it if u want a b-kit... and the RR ECU wont do the job either... u need a controller unless u go to a milder setup like the Riva SC or RR SC

    FYI

    The Riva ECU is mapped for their 50 lb injectors. I get 100's of PM's and emails from people asking me about running this ECU on their stage 2 kit, or other modded ski and wanting to do so with stock injectors. If you are going to run this ECU you MUST run the 50 lb injectors. If you try to run it with stock injectors it will melt your engine down from running lean.

    So those wishing to purchase one of the Riva ECU's be sure to factor in the cost of the injectors too.

    You can run this ECU with a B kit supercharger, but you will need a fuel controller and 50 lb injectors (which you will already have)

    So the fuel controller can piggy back the riva ecu? If so then what is the advantage of the Rotax over the Riva? Is there an advantage?

    We dont know of any advantages as the Riva ECU has not been released yet.

    A piggy back fuel controller will work with a stock, Rotax, or Riva ECU.
