    Rotax Racing ECU is absolutely ridiculous

    Hands down one of the best mods you can have done to your ski. I picked up 400 RPM's as soon as I installed it and 2 mph without repitching. Its expensive but well worth it.

    I know, the ecu isn't something that yanks your arms off when you install it but overall when I try it out against my friends and on the gps you can definately tell its there.

    Yes, the two best mods I have done to my ski are the RR ECU and the B kit. This thing is a completely different ski than it was a few moths ago.

    Ditto, what Jarrett say, be sure that you grap your ski handle bars very tight or be ready for a swim...

    p.s. did you buy the skat-track exit nozzle with the adjustable rings already? in my opinion this is a "must" do mod with your new "B" SC set-up, this mod would keep the ski away from the rev limiter and increase the top end speed at the same time

    400rpms ?!?!

    That is almost +3-4mph. Did you have the stock exhaust before ?

    almost nothing, lol, a b kit and an ecu.

    yea i ordered my nozzle from riva along with the new 15/19 3 blade. Im gonna take off my 14/19 and run the 15/20 for now then start tweaking both setups with the rings and see what gives me the best results.

    and kinch I already had the exhaust before the ecu, don't know why you ask though.
