09 Si, New tune with knocking

[Theunholy]

Hi

I live in CA so only have 91 octane, I have a stock 2009 Si with K&N intake and just a catback, recently bought a Hondata flashpro and tried to put a tune into my car. after uploading the file for "completely stock,tuned".
I have experienced some knocking at 2k-4k rpm. I know there is a file for K&N sri, but with that file I also experience knocking. I hope someone can take a look and the logs. does the 91 fuel matters? Thank you so much.

You should reduce the timing in the areas you get knock.

thank you for replying, I'm not sure sure how to reduce the timing on the Hondata yet, would you be able to help? Thanks

Just want to add the calibration that i was using. Hope this helps.
