    Procedure for swapping ECUs and Throttle Bodies?

    Anyone familiar with this process? Frank and I are going to attempt it this evening and are looking for help. Thanks.

    I was under the impression that you could take a Rotax Racing ECU out of one ski along with the TPS (throttle position sensor) and put into another ski.

    The RR ECU marry's itself to the TPS when you originally install it.

    Per Mark:

    Taking the throttle body off should take about 10 minutes. You just remove the pipe to the IC, unplug the TPS sensor and Idle Bypass plugs, remove 4 screws, remove throttle cable and you are done.

    i can't find a thread i was looking for all night long

    some forum member like a month or two ago came on here outta middle of nowhere, was a newbie to the forum, and posted something about using a certain version of BUDS that allows you to do something with the RR ECU or something like that. I remember reading it, and can't find it.

    reason being, I think I need to either reset my RR ECU throttle info stored in it, or reset my throttle body sensor, or swap throttle bodies with the original ECU owner. I have no clue.... just thought i'd share see if anyone recalls reading something like that also?

    edit.. wow, this is an OLDDD thread, lol

    one other thing... how many people have successfully shared a RR ECU between multiple skis for testing purposes with no issues or idle or top speed/rpm problems?
