RPM limited on 2005 Yamaha WaveRunner FX High Output - FX1100D
After the Dealer replaced the ECU I am having a new problem.
When running at full throttle, the Waverunner will top out at 9,000 RPM for few minutes and then jumps to 10,000 RPM for a few minutes. ...then it goes back and forth between 9,000 and 10,000 RPM every few minutes. It runs smoothly at either of these RPM.
There is a difference in the sound of the engine when it is limited to 9,000 RPM. It sounds more muffled. Even when riding at much lower RPM you can hear the engine transition between muffled sounding and regular sounding every few minutes.
It also will not idle smoothly. It shuts off at low RPM.
It ran perfectly before the ECU was replaced.
