CB1100 only has a crank pulse sensor on the end of the crank (with "missing teeth") that determine crank/piston position. Ignition and fuel mapping can then be determined by the ECM with input from the other sensors
But since the camshafts are spinning half of crank speed, how is it determined which if the two crank rotations the ECM supplies fuel on? To paraphrase LakeWylieJoe, there can be a wasted spark, but not a wasted squirt. So how is that determined?
