Help Road tune, Logs & LV inside. Seeing knock, how to correct map?

Hey guys im looking for some input on my logs I have. I have a 04 wrx running 94 oct on testes1010 93oct map.

Catless up & catless turbo back exhaust
k&n drop in filter.
all 100K maintenance items have been done + pcv valve, IACV clean, maf clean.

I am a noob to tuning so I need some help on understanding the logs and LV. How do I interpret where the knock occured, and apply changes to my map. From what I know so far, im assuming some changes to the base timing table are needed?

The knock i do get is at 50% throttle and in boost. Maybe this is in OL?

some input on what to correct would be nice, and ill go ahead and look into how to correct them.

thanks guys.

From what I understand, you generally don't touch the CL fueling tables, only the OL, so I would start there. I'm definitely not an expert or anything but I would start by looking at the timing tables and pull timing where you see the FBKC is negative (ECU is pulling timing), and pull that amount of timing at that spot. You basically want to see all your FBKC's as close to zero as possible. Also, make sure your IAM is 100% (16) across the board.
