Hello everbody,
my Corvette 2016 C7 Z06 shows knock retard whenever the vehicle is not in steady state.
Even at slight tip in. First I thought it's all false knock.
Now I saw knock retard also at high RPM during a WOT pull which looked real, cause it was shown which cylinders were affected.
I also have the feeling the car ist running a litte too lean because the exhaust tips dont get that black anymore
and coolant seems to get a little hotter.
Vehicle is running RON 100.
Does the engine might have a problem?
How could I investigate it?
best regards
Max
