    Finally going with a R2

    I should have a R2 by the end of the week. According to the website

    R&D R2 ECU; Reprogrammed ECU to allow 8750 RPMs, Raised Boost limiter to 17 pounds, advanced ignition timing for high performance recreational use. R2 works great with stock, C1, C3, or C5 Monster Wheel Kits, or any wheel kit rated up to 18 pounds of boost. 91 octane pump fuel should be used with R2 reprogram. 93-95 octane fuel is recommended for closed course racing conditions where high engine loads are present. The R2 program file does not require a Powershot Fuel Tuner for use with C1 and C3 Monster Wheels.

    Right now I have a 13/22r prop. I want to be around at least 75mph but would like to keep my RPMs around 8300-8400. Based on my setup (see signature) will I be able to see those speeds at the given RPMs? What prop should I get to keep my RPMs under 8400?

    Do you mind if I ask why R2 over R3? Im trying to decide what ECU to do myself...

    I actually have a choice. My cousin has both so whichever I want I can buy. I was told with my wheel being smaller B1 the R2 would better suit me. Just from the the two descriptions the R2 has advanced timing the R3 has more aggressive timing, I'm not a wrenchhead by anymeans but I'm thinking the more timing the hotter it will run? I'm a rec rider with the occassional race, but no circuit. It would only be straight line or maybe some off shore. I can try both back to back and provide results. My goal is anything over 75mph as safe/reliable as possible.

    My wifes FZS has a Riva filter, ribbon delete, C1, R3, R&D grate and a stock VX plate and runs 76.6 with a stock prop... I would think you should be in the 77-78 mph range with your setup in your sig.

    That's nice, how many RPMs are you turning?

    It was actually like this, other than the VX plate, when I bought it from a forum member. I'm not sure of the rpms because I haven't hooked up my PET to it yet.

    Should I not be too concerned with my RPMs if I'm turning over 8200?

    to be honest IMO R&D does a horrible job on explaining these. But based on the notes on their website you only need a RRFPR when using the R3 (non V version)
