I have a 2014 XL1200X that was idling fine and started have a high idle [3400 rpm] for a few seconds at crank. I have a DynoJet Power Vision on my bike and one of the gauges is set to displays the IAC steps. The steps are set at 160 steps at crank and gradually lowers to normal idle rpm after startup. Also at random times while riding the IAC steps all return to 160 and cause a high idle. The only way to clear this is stop and turn key off. The tune has not been changed and the bike cranks and runs really well other than idle. I have also check the engine temp, IAT, TMAP and TPS sensors and all seem to function properly.
