Default sensor

The red cube uses a impeller that passes a sensor. if it is subject to vibration or pulsing fuel loads, the sensor seems to sometime double count the passing of the impeller, from what i understand.
I suspect you would see an error difference whether or not the engine is leaned to the point of roughness.
