I don't think there's much to worry about there as the first log shows a bit of minor timing retard adjustment via the Fine Knock Learn. According to Cobb you only need worry if the value is greater than +/-2.
I wouldn't be too concerned about single counts of fine knock learning (-1.4), unless they are covering a wider range of the WOT run or get worse. Fine knock learning is a bit tricky to determine when you are currently knocking as it will be re-applied to a load/rpm range surrounding the original event. So, you see corrections that are not current knock events.Few tanks through since I last logged so I gave it a whirl again. Seeing some interesting results.
'11 STI - 94 Petro Canada Fuel in Canada
ACN91 Stage one Cobb OTS Map
Sport Mode - Back to back runs, same road (Down and turned around)
DAM stays at 1. No Fine Knock. Does show Fine Knock Learn and a slight timing correction. Both logs recorded within 2 mins of eachother
S# Mode - Two logs, back to back. Middle of the road which was a smoother then the first. First log shows minor Fine knock learning values. Second log is crystal clear. Both logs were recorded within 1 min of eachother
All 4 runs were logged within a 10 minute window
a Protune is in the cards for the January timeframe. Thoughts?
