Always assume that if the knock sensor is going off there is too much timing or a problem. Start low and work your way up.

Not necessarily, sometimes too little timing can also cause knock. In general though, yes, pulling timing should fix it.

as a few others have said, you need to rescale your tables.

you need to change the points of measurements of your charts. your timing graph goes up to a max load of 260. That would be fine if your hitting 220-230 load, but your are coming close (or going over, way over) that load. imagine a square thats 10 cells by 10 cells and than you pick a direction and drive 14 cells. Your ecu has no idea what to do and knocks like a 13 year old trying to get into the bunny ranch

I looked quickly for a link on how to rescale your tables but not having much luck from my phone. im sure someone here can throw up a good link

Just pay a professional to tune the car. You are in way over your head.
