    RIVA ECU Install on 2nd Ski, how-to?

    Hi guys, can someone please familiarize me to the process of installing a Riva racing ECU that has already been programmed onto another ski?

    Is it a direct swap since the ECU is activated or is a phone call to Riva in order and a trip to a Seadoo dealership as well?

    Thanks

    I know that when activated, it is calibrated to the tps on the t-body, so that would have to stay w/ the ecu, don't know about the mpem and what the hell would u need to do to use a 04-05 ecu in a 07????????

    the Rotax Racing ECU can be reset at the factory (90 USD ) So you can learn the TPS 0-position again on a new ski

    Swap the Throttle bodies with the ecu that it was mated to.

    Most of the time it will work fine without swaping TB.

    and IF it doesn't work fine, can you just reset the TPS on BUDS?

    yeah, I am more interested in using early ecu in late ski, but there will be no lanyard programming needed

    but IS the TPS re-writable, bc skis do vary from time to time... it can be the same year ECU and not function properly if the original ski's TPS is different from the second owner

    what functions on a Riva ECU are able to be editted on BUDS
