I wonder who told us about those Dam Unsynced = "to be out of sync" Throttle Bodies? :lamer:mjw930 said:I wouldn't be so hasty. It looks like you have either not enough samples, you're losing packets in the data log or something is preventing the butterfly from opening all the way. You got to 98.2% on 2 occasions so I'm guessing there's something keeping the rear butterfly (where the sensor is) from opening all the way. Check you cables, throttle plates, etc. Could be your throttle plates are out of sync.
