    Question 2012 Rxp-x Ecu questions

    Will taking the rev limiter off(ECU flash) on a stock 2012 Rxp-x do anything to hurt the machine with no mods??
    Will it void warranty?
    Will it push it over the 70mph mark?
    Which ECU kit should I use etc.......thanks in advance.

    Will it void warranty? Only if you have an issue with the engine in the future and the dealer discovers that you reflashed it. They can tell by looking underneath it and seeing the access hole drilled through it AND seeing the rpm levels above stock rpms using BUDS.
    Will it push it over the 70mph mark? YES because the GPS speed limit will be bypassed.
    Which ECU kit should I use etc.......thanks in advance. VTECH from online store.
    What you have to decide now is what RPM limit do you desire for future mods.
    most guys say up to 8300 stock valve train ok
    8300-8500 requires at least retainers, rrfpr, afr monitoring
    8500-8800 all above plus springs
    8800+ all above plus lighten valves

    It will certainly void the warranty.
    And you do not take the rev limiter off, you just raise it. Taking it off would certainly end bad very quickly.

    Riva will be releasing a Stage 1 kit soon,, just wait . Most stage 1 kits will get you 70+. These are usually bolt on equipment (Besides Impeller). The SCROM will not remove or alter your RPM but will remove the GPS MPH limiter set on the ski which is 68. This is a snap on and off product so you will just need to remove it and all the other bolt on before you take your ski in for service. You can look at the the stage 1 kit for the 2012 RXTX and get an idea.
