Just curious what everyone's experience is like when dealing with false knock while using audio knock detection equipment. An example of this is a 4G63 with a multiplate clutch. When the clutch is engaged during gear shifts it sounds in the headset like the engine is knocking. The factory knock sensor also picks this up as knock.
I imagine if knock control was being used the ecu would retard the timing to compensate for this and it would have an effect on the response of the engine after the gear change. I am not using knock control on this particular car but just curious what everyone else is doing with regard to this.
Typically the frequency that the clutch noise is occurring at should not be the same as actual knock, so if you have the ability to tune the knock frequencies, this should not be detected by the ECU and shouldn't cause the timing to be retarded on the shift.
