    Can you remove the speed limiter on the gtr?

    I have 2 gtr's and they are limited to 65mph. I know the engine is capable of more rpms. Was wondering if you can remove the limiter?

    Sure you can. With an ECU reflash you can spin the RPMs as high as you want. Keep in mind that it's advised to go with a valve train upgrade if you plan on going above 8400. The R&D or V-Tech ECU reflash is the best route for keeping the costs (relatively) low.

    Send your ECU to California for the R&D service $675ish or drop $1000 for Vtech and tune yourself both good options that you won't regret. You will notice gains all throughout rpm range.

    Do not buy Riva or R&D speed control override module (SCOM). If you want real results you have to get rid of the factory limiters in your ECU. The ECU flashes are expensive but worth the money. Speed cost money. Gotta pay to play.

    Yes it is a new program flashed into the ECU along with removing all the limiters. Supporting mods like a air intake/catch can/flame arrestor removal will be even better after reflash or even before. Vtech seems to be the most popular for Seadoo because you can flash back to stock if need be.

    Yes the tunes will unlock some more power besides removing limiters.


    The Vtech Maptuner is the Handheld unit you use to flash the craft with.
    You can also check and erase errorcodes with the maptuner, if you need we can also enable functions as reset service, reset engine history.

    The handheld can be shared with friends that also has supported crafts that wants to tune.
    But you will need 1 tuning license every craft you want to tune.
    After a license is linked to a craft you can freely change betveen maps and grow with the Ski and you can also go back to stock if you would want to.

    Alse Edit and autotune functions is available for most Sw versions but it requires a Datalogger to safely edit/customise the tunes.

    You can buy everything here:

    Ok, here's a question..
    my 2013 RXT-X doesn't have the lake water temp sensor (the '13 GTX Limited iS 260 is the only ski that comes with it), I want to add it and I bought the sensor and pins for the ECU, I wired it to the proper terminals on the ECU plug hoping that if the ECU sees input on those terminals it would work, but apparently the ECU needs to have different flash to enable the sensor.

    can the Vtech flash enable that in addition to removing the limiters?.. and is it worth it to remove the limiters on an otherwise stock RXT-X 260 (I do have a Riva Gen III intercooler)?

    Thanks!
