Is knock that you can't hear anything to worry about?

:hail:IROC-Z

 

Its a lesser thing to worry about compaired to audiable knock.

But any form of knock is a bad thing, not only that but its a force against you, why not get rid of all the knock, make more power, and be more healthy for your engine.

 

Knock is bad, mmmmmmmmkay?

Inaudible detonation can still do damage. If you know it's there (presumably via scan tool) then get rid of it.

 

if you cant hear the knock how comes you know its there? gets me thinkin again, if a tree falls in the forest and noone is around, will it make a sound? anywya back to the subject how doyou know there is a knock?

 

With your knock sensor

It can pick up on the harmonics knock makes well before a human can hear it.
