I have this FI error code on my bike that I''ve been fighting for a while now and I'm growing quite angry. This code indicates that the Throttle Position Sensor is the cause. I've replaced it, still an issue. I've completely unplugged the power commander, still an issue. I tested all the voltage everywhere between there and the ECU, according to the manual, and it all tests OK. I replaced the ECU, still an issue. I don't know what the hell i can be at this point?! Anyone have any further suggestions. This bike has just over 70K on it so it's about time for stupid shit like this I spose. It's not totally consistance either. I'll "fix it" then ride it and it runs like champ. But then I'll ride to work (bout 25 miles) and it'll error out on the way home. Advice what to check next?
