    Does this mate with the throttle body?
    Meaning first time its plugged in it read the vin of the ski and becomes none usable for another ski.
    Or will I need to get it reflashed?

    All you have to do is put it in you ski and take it to a dealer with BUDS and they can marry the ecu to your existing throttle body, or you could remove the throttle body and send along with the ecu to Riva.

    rotax racing ECUs are inaccessible on BUDS at the dealer...

    these ECUs have nothing to do with VIn #s...

    you can use it in ANY ski of the appropriate year... they dont lock themselves down to only one ski..

    a critical INPUT to the engine manangement system is THROTTLE POSITION. on a STOCK ECU, the throttle position is re-settable.. meaning each throttle body can be minutely different in their rotation setting.. so you can ZERO out a stock ECU...

    RR ECUs this is not possible... the first ski is gets connected to when new, it reads that ski's TPS sensor and engraves it in stone inside the ECU what zero degrees rotation was on that throttle body...

    if your throttle body rotation at idle is the same... then no problem, so long as it is reasonably close... which a large majority of them are...

    BUT, if your throttle body is setup a bit different, there's no fixing it... zero degrees in the RR ECU will no match the reality of zero degrees in your throttle body... which will cause an erratic idle and a slight misconception of the fuel mixture through the rest of the TPS range


    regardless... his asking price, is an absolute STEAL OF A DEAL, i think this is the cheapest RR ECU to ever hit the market

    I've never had a problem moving RR ECU's from one ski to another either.

    Vin was just a example. Like my Truck and the Power Programmer. In my truck it actually read the Vin.

    Will read this until I totally understand. And yes the price is what caught my eye. Even though my machine is not ready for a ECU yet.
