Hello, i can't get rid of a few knock counts . In a 24 min datalog, i'm having 27 knocks and all are in the CYL 3. I already try to reduce by -2 the timing and nothing happens or change the spot where it occurs. Always occur in the same situation, when i pull 25% of the throttle in 1st or 2nd gear between 2000 - 3000 RPM. If i drive very gently or if i do WOT pull, i dont get any knock. In the area of the knock my A/F is a bit rich (+5%) .

Im thinking in two options

High IAT: 110°120°F (Ambient 73°F)
K&N Typhoon causing false knock

MODS: HONDATA, K&N SRI . everythingelse is stock


I hope you can help me please. I know 27 knocks is not terrible but just want to make sure if those knocks are real or not.

I dont know why i can't upload the calibration and datalog. So, here you can find the files https://www.hondata.com/forum/viewtopic.php?f=25&t=22556 .

Thank you
