    Installing racing ECU on 06 and up 4-Tec's

    I just wanted to make everyone aware that due to differences in the 06 model TOPS valves that these models need the 06 spec Racing ECU.

    Using prior years ECU's will not work on the 06 and up 4-Tec's

    While im on the subject, Rotax Racing stock class ECU's are also year dependant. You need the stock class ECU that was made for your year model ski.

    Good info. Jerry, thanks.

    In the near future, when I go to install my ECU, I will probably be asking you a couple of questions... JUST TO BE SURE!

    It's nice knowing that you and the others on this site are here to help.
