2007 C6 Z06, 110 LSA +4 cam with stock rockers (no roller tips). Using tuned MAF only. VE disabled until the HP Tuners VE tuning software is released.
Knock retard at light throttle cruise below 2000 rpm in 5th and 6th gear.
93 octane BP; 100% gas no ethanol content fuel.
Tried open loop 13.5 A/F; still see KR.
No KR at full throttle.
Knock sensor values are stock LS7.
False knock maybe?
Reduce knock sensor sensitivity?
With as wide spread as that knock is, I'd run the tank low and put some race gas in it before I determined it was false.
Noisy valvetrain?

Why don't you post up the tune so we can scrutinize the spark curve.

Problem solved.
False knock.
Valve spring and retainer on cylinder 7 exhaust valve had a problem causing
a problem with the rocker arm which the knock sensor interpreted as knock.
Same problem arises when you install roller rockers on LS motors.
All is well again.
Great to hear!
