High Knock count above 0* VTC cam angle
Posted: Sun Aug 28, 2016 11:25 am
Hi all,
I am having some issues with my tune. My knock count shows really high, above 1000-2000 knock counts when the VTC cam angle starts to advance under normal cruising/driving. 10* of ignition timing was pulled atleast to try to see if this high knock count would go away, but it didn't help at all. Once the cam angle map is locked at 0*, there is no knock count at all. Engine sounds and drives OK, no symptoms or signs of detonation/knock under 0* or 10*, 20* or 30*.
My setup is a stock k20a2 turbo with upgraded supertech valvetrain 1021HD and SVM 212.
Any Suggestions?
