The only thing I see is that your car has learned it has to pull 1.4 degrees of timing on 91 octane and 1 degree on 93 octane at certain load levels. Looks like part throttle, high loads, such as being in a high gear and then mashing the gas to pass someone, and on shifts after WOT.

As for the learned timing reduction, probably needs a little adjustment in the tune to richen up the AFR where it has learned that it saw knock.

What mods do you have? There are a couple that could cause that with an OTS tune.

looks about the same as my 2011 STi. from my limited knowledge, I wouldn't worry about FBK and FKL if the throttle is not at 100%. I just wish that this part of the subforum gets policed by Cobb professionals regularly to explain.

50 in 5th gear is at like 2000-2250 RPM's the reason its seeing a fine knock learn is because you are lugging the engine. At that speed you need to downshift to 4th, and then you will probably still see fine knock learn because the ECU has learned that you lug your engine, and its trying to prevent a knock situation from occurring.

Re-set the ECU, avoid all lugging situations like he said and see if it comes up in later logs again.
