As far as I know, yes. Knock #1 is what you definitely need to scan.

KR is what you want to scan.

Knock 1, and 2 are likely the noise channels.

Knock 2 was reading 120-140!!! I read that knock 2 and 3 weren't for our cars though?

Knock 2 isn't Knock Retard....right?

Only knock retard 1 works on our cars.
