High Idle - 2200rpm
Recently had an ecu fail and have since had it repaired. I have just put it on the ski and it is now idling at 2200 rpm, previously it was 1800rpm. Any thoughts? I pulled the flame arrestor from from the manifold while this ecu was being fixed. Could this cause a higher idle?
Im guessing that the easiest fix would be to take it down to a dealer to hook it up to buds and adjust the idle, unless the idle vale is shot.

Check for an air leak on the inlet manifold if you have had it all off to do the flame arrester - Just a thought.
Your idle will always be slightly higher out of water that when the craft is in water as there is no resistance on the prop.

Look at the positive side, holeshots better

I think getting the TPS reset is the logical answer. Given the ecu has been apart i think the values need to be reset. I never had the ski idle this high out of the water, maybe 1900 but never over 2000.

According to the workshop manual, resetting the TPS also resets the IAC within the ECU. Hopefully the IAC valve itself is not faulty.

reset TPS if that does not fix it, then you more then likely have a vacumn leak on manifold from when you removed it.
