    2010 RXT-X 260 Unlocked

    I sent mt ECU to Malte and Nico Russ had the speed/boost limiters removed and the rev limiter set to 8350. I ran the ski Friday and had multiple runs of 70.3, 70.4, 70.6 @ 8200 RPMs on full tank, 82 degrees and humid.

    Friday Night/Saturday Morning we pulled the porta potty out (air box) and replaced it with 4" rear air, filled the ride plate holes and removed the flame arrestor from the intake manifold. Ski ran a best of 72.2 with multiple 71.6-71.8 runs on 6 bars of fuel. The temp was 82 but the humidity seemed worse. Same RPMs.

    I have no doubt the ski will run 73 on the buzzer, especially with better air.

    The rear air in the pics is temporary.

    Next:
    - Try a set of skegs to get more of the ski out of the water but if they kill the carving ability of the ski they are coming off.
    - a thermo or open loop
    - water box
    - a prop. Has anyone pulled the pump out of this ski. Is it the same pump Doo has been using? If so we have some props we can try.

    Very nice. How long did it take to ship out/get back? Did you just fill out there "Kontakt" info telling them that was what you wanted to do?

    Other than the huge sticker I wonder if the dealer/warranty would know it was modified...I suspect so.

    At 19 hours I'm still suffering with some weird fault code P0106 that is causing the power on my ski to fall on it's face. I think it's a map sensor so they say. They were supposed to replace it but my normal service guy was out and I"m thinking they didn't. Anyways back to the dealer it goes. Highly annoying.

    Took about 3 weeks. I just emailed Malte.

    There is someone on here that runs a 15/22 in his RXTIS. I am not sure what difference it made.
    I did a comparison when I had an 08 RXT with a 15/22 against a stocker. The solas made a substantial difference.

    THanks for the post.
    73 mph was my estimation on 2010 T-X with just getting past the ecu and air intake mod. (no power adders - stock prop pitched to be at correct rpm)
    No hull or grate mods. Very Nice.

    It was $800 for the service an around $340 each way for shipping. Everything worked exactly as Malte said it would.


    Does Riva have an ecu for this ski?
