    I had the Rotax ECU on my X and really did not like it. The idle was rough with the 60lb injectors and you no longer have knock control. If you want a higher reving ECU your best bet would be the seadoo centre ECU.

    You rough idle was from running lean, once you add more fuel they idle just like a stock ECU.
