Just rode with datalogger. Looks interesting or better yet strange. Works very well but the O2 voltage is either close to zero on overrun with closed throttle or around 0.9V when the throttle is open any amount at any rpm or speed. Either the 20102 TuneDyno is running awfully rich or the logger does not show the voltage correctly. Any experiences? Seat of the pants the bike runs just fine and feels strong without dead spots or any hiccups.
