Default fine knock learning issue? 04wrx stage2 LOG inside

https://docs.google.com/spreadsheet/...jFnd3I4WDlYYkE

took this in 3rd to redline and then to 4th for a little ways...

loaded it and there is -1.05 when im in 4th gear

ive only ever logged in 3rd gear, so maybie this always happened?

i just fixed a fuel leak on the passenger side fuel rail at the stupid soft line connectors. installed a perrin turbo inlet and cobb sf intake and air box.

heres the car
-Cobb AccessPORT stage 2 93 octane ( just filled tank about 20 min prior to the run, and its about 25deg out)
-Cobb 3'' High Flow Cat. Downpipe
-Perrin 3'' Cat Back Exhaust
-Grimmspeed ceramic coated uppipe
-Perrin Radiator Shroud
-STI Top Mount Intercooler
-Walbro 255 Fuel Pump
-Perrin Turbo Inlet
-Cobb SF intake
-Cobb SF air box
-Perrin BPV hose
-Samco turbo outlet to "y" pipe

is there any reason to be concerned with the fine knock learning?

It seems you had a single knock occurance at about 5100 RPM. My suggestion woul dbe to run the same pull again and look at it. You may need to go into ATR and just remove 1 degree of timing from that section of your map. You also seem to be overboosting a bit.

The Fine Knock Learning value appears to be going down, but a battery reset would revert those values back to 0. This would help you determine if it comes back from a consistent issue or not.

What version map are you using? If you are not already, I would recommend the v3.10 that can be downloaded straight from the Support section of our website. They are all new maps.

Thanks for the responses guys, it is the 3.10 93 octant version. And i had the battery out for a whole day while I took the intake manifokd off to do repairs. This log was after a quick test drive the night I finished the repairs, and the following day on the commute home from work after a fresh full tank of gas. So its realitivly fresh except the trip to work in the morning

Can't I just reset the ecu with the access port instead of pulling the battery also?

Looks like in the second log the fine knock learning is decreased and being learned away. Good thing.
