This is a old thread but I'm still having same problem. Please do not reply me again "whole number rounded..."

I attached my calibration and my datalog and if you check it there is 4 degree difference on the calibration and datalog Check 7500rpm you will see that ignition advance should be 32 but datalog recorded 28 degrees. Ignition compensation tables are set to zero so there is no igntion retard because of iat.

Datalog recorded with the calibration I attached.

Thanks in advance.

Try zeroing the knock ignition limit tables and see if that has the desired effect.

Thanks for reply. It gives desired effect. I thought that this tables are not used unless "use stock knock control logic" enabled.
