    Rotax Racing question about old RRECU & New SCer Impelle

    Will the OLD flash RRECU work with the New RR SCer impeller and stock injectors?

    I ask because I am about to buy a old Flash RRECU, but for the use of the New SCer impeller.


    Thank you!!!!

    WAG Probably... depending on Ic, prop,etc. The old version didn't have as much timing and more fuel than the new version. Ya know you need to check it with an A/F guage.

    Austin--Should work---the stock class ecu works great with the RR SC impeller. In our heat you will have enough fuel.

    So Ray, do this mean that you are going to test the new RR SC impeller with the stock 38's injectors?? do you have a A/F meter in your ski? thanks
