Knock retard under WOT

I have a flat 2 degrees with two little spots where it goes to 3 degrees knock retard. Is this ok or should I be retarding timing 2-3 degree?

Retard the timing there until there is no knock and no knock retard.

I have the same problem with a flat 2 deg knock retard.

What does it mean when I see KNOCK LEVEL as high as 83% at some short intervals?

On the other hand, does it mean I can increase the timing at every places where there are no knock retard?

You should really only advance timing on the dyno where you can see power increases and make sure you are not getting detonation.

i tried retarding sometiming it just made the car run like garbage. Is there a possible way to get a FPCal for higher compression?? IE an altered ignition table.

Start by telling us what calibration you are using.

Honda knock control does not work as you would think - it will retard even if there is no knock. Wiith the MAP calibrations you can change the knock sensitivty.

I am using the Basemap on MAP setting, for K&n intake, raceheader, and stock exhaust.

I am currently 12.1:1 compression with hytech cams. Is there a basemap with less timing and more fuel??

I posted my datalog in the calibration request part of the forum.
