Crankshaft Knock Detection
Would the BEST way to sense engine Knock be from Crankshaft Acceleration Measurement ?
No "hidden" microphones that ALSO hear pistons, valve train, etc.
Trust that it CAN BE DONE, an OBD II Federal requirement !
When my ECU "feels" crankshaft vibration, it will retard the Spark Instant for all cylinders durning the next revolution of the crankshaft.
