Knock count for each cylinder.


The knock count is increased each time the ECU determines that the knock sensor records a knock type event from the engine.  The knock count is recorded for each individual cylinder.  The knock recording of the ECU is not affected by altering the knock sensitivity tables.


Note that other mechanical noise may be interpreted as knock by the ECU.  Supercharger noise and exhaust headers are the two most common causes of 'false knock'.
