    ? about installing a used Riva ECU

    I bought a used Riva ECU for my 05 RXP and I am just wrapping up this project. There were no lanyards included with the Riva ECU and I sold the stock ECU and lanyards. I bought 2 new lanyards from the online store and know I need to go to the stealership and have them do some work with the BUDS to get this thing finished. I don't have the best confidence in these guys so I was hoping you all could walk me through what they are going to need to do.

    Is it just a swap ECU function and program key function or is there more to it than that? I understand that with a brand new Riva ECU you need to call Riva with a VIN for an activation code. Do I need to have an of this info?

    Thanks in advance!

    I'll PM you if I am able to take you up on your offer. The truck went to the dealership and they tell me it won't be back til Monday at the earliest. Just ordered up a hitch for the fiance's ride so we have another tow rig in the future.

    My riva and my rotax ecu worked with any lanyard, never a problem going from ski to ski, but the riva did stay w/ orig. mpem and cluster it was activated for. Again, anyone could have jumped on my ski with their own lanyard and rode off

    Maybe there is a place in BUDS to de-activate DESS......

    It gives me one long beep followed by standard 4 short beeps at 3 second intervals. I'm assuming that it's the lanyard needing to be programed at minimum.
