Just a little more on this.
In Knock Control action, what is the ' Threshold' and the 'Noise Scale Factor'
I have values of 255 in both these. I know they may well be specific to the engine, but any ideas on a start point?
Ive set vems.ini to log
knock_cyl_0_knock_val, "knockvalue", int, "%d"
knock_cyl_0_noise_val, "knocknoise", int, "%d"
