But i thought the scan gauges read timing retarded in degrees to combat knock. Now is kr on a gauge reading retard only during actually knock or false knock? or is it reading the actual knock or false knock thats accuring in degrees? Now its possible gm programmed that retard to combat knock that is more probable during shifts.

Edit: So if we took those values of what bill posted and set to zero would the car be more prone to knock or would it just put for stress on the tranny?
What Bill is saying is confusing an issue that really isn't even an issue.
The torque management system is just that... torque management. It has nothing to do with knock.
KR is either knock, or something else making noise that falls within the frequency range of knock.

This is 3800 101 here.
I'm sorry you guys are being confused by Bill.

This is a decent write up that seems relevant.
