Rotax Racing ecu
Just installed riva intercooler, riva thermostat, 15/20 prop and rr racing ecu.
Check engine light come on as soon as I start riding and go over 5000 rpms, Is this normal with the rr racing ecu. Thanks

Definately NOT normal. You should be able to hit 8400 rpm's with no problem.
Im sure the guys will ask you to specify more on the ski. To check all connections to the intercooler and such....Just wait a bit and a pro will let you know where to start.

What year ski?
You have to remove the piggy back knock sensor update wire harness for '04 RXP's and you manually have to cut the resistor out of the wire harness on 05 models.
This is why you are getting the check engine!
