    Yes, i was basically running the Riva stage 2 with the RR IC. All i can say is adding the ECU into the equation is night and day.

    The new flash ECU is leaps and bounds over what the old flash used to be.

    But the old flash is a safer bet if you don't want to play with the valvetrain...And hey look here is one for sale....

    Jarrett, as long as you pitch for 8400 RPM's you are good to go. AND you reap the benefit of unreal acceleration

    Plus 2 more mph is on tap if you ever do any valve work.

    Jerry I'm going to have to disagree with you here. This may not come across as I intend....I'm not trying to be an asshole, but for those of us who ride in choppy water this is not a good solution. Where I ride I'm constantly becoming unhooked and hitting the limiter hard with the stock ECU. This isn't intentional but when I'm going 50-60mph across the lake I hit a lot of wakes and get slightly airborne this causes the ski to hit that limiter. I would imagine hitting the limiter as hard as I do sometimes would float valves in an instant.

    Having the rr ecu with a "safe for stock" rev limit would be ideal.

    I see your point, but there is a big difference between being under load at 8600 RPM's and kissing the limiter for a second while coming unhooked.

    In fact, i think it was Mark Underwood that told me that even with a stock ECU if you are running WOT and come unhooked that your engine reaches 9000+ RPM's even though your stock limiter is set at 8200.

    So what benefit will I get? More rpm & top speed? Better acceleration?

    Today i sold all my stage II race parts including my R/R remote intercooler to a local guy and i will be starting from scratch all over again and definitely the first thing in my list is the new R/R flashed ECU/ with Rivas power cooler with the new R/R 2 PSI 15 HP SC impeller as soon become available in the marquet, i think that this combo is the BOMB!!!!
