That is the power commander I have in my bike right now. I was hoping someone on here could explain what the three buttons at the bottom are supposed to do (yes they are buttons not lights). Also the gauge on theleft side is a mystery to me, when the bike is in neutral idle the gauge light is always at the bottom, when I rev the throttle the light makes it up to the center of the gauge "0" in the picture but never goes positive. Is this normal operation for a pc?
