    Rotax racing ecu problem

    This is the 07 model, I’m not sure if this is normal but it doesn’t beep when the key is in it or the two beeps when you first put the key in. The speedometer doesn’t work, it starts reading low number at high mph. When I first get to the ramp the ski bogs I guess when it warms up it goes away. It had no problems before the ecu and valve train upgrade. Any help would be greatly appreciated. Thanks

    Is it a new ECU or a used one you installed?

    Its brand new it works fine other than those lil problems. I just finish running my ski and thanks to your skegs I just hit 79.91. They weren't kidding about holding on when you turn. All I need to do now is fill the rideplate holes and I should be passed 80

    How much speed did you gain with the skegs?

    I was talking to him and he said 77.98 before and then 79.91 with just the skegs added. Then 20 mins later after going out again he dropped to 77's again. Neither of us thought heat fade kicks in that fast

    They gave me 2 mph but for some reason this sky has always given me great first passes. I think the skegs really helped the nasty hooks on the back of my ski. I filled the ride plate holes last night and gonna test today. Then back on the trailer for the the trip to mud bug the next day
