In December I purchased a Power Commander USB III for my 2008 Roadking. With the Power Commander installed on my bike it will not idle. After calling DynoJet and talking to the customer service rep. he told me to do several things. They include: Reseting the unit, adjusting the throttle position, bending the power connector for the ground, changing the map and replace the fuel line. None of these fix the problem. Also, I have installed a new fuel filter, fuel filter shell, fuel regulator, quick disconnect, and crank sensor. The Roadking is stock other than a SE air cleaner. I have read several posts that others are having the same problem. What did they do? I have made about 5 calls to DynoJet. They don't seem to care.
