Good day everyone, Finally got an AP V3 for the 2013 STI, installed OTS 91ACN and reset the ECU around 50kms ago, the car has been running on Ultra94 since day one. I did 2 datalog if anyone could please give me some advise on the feedback knock. None of my logs have any Fine Knock, I did one datalog using S mode (log 1) and the S# mode ( log 2) it's the one that shows feedback knock up to -2.45, any advise will be greatly appreciated.
