You need to reduce ignition where it is knocking - in this case, 1300 rpm @ 70 kpa.

Zperformance, it doesn't knock all the time, sometime it will shows up like 1 or 2 knock at cylinder 2 &3 during heavy stepping.

Hondata, how do you do it? i'm new to this, do you have screen shot or step by step process?

Look at the datalog and see what the knock count increases. You can overlay the knock count on the tables to make this easier, but the simple way is to just look at the datalog. In your case the knock count went up at 1200 rpm & 70 kPa at the 7:50 mark, and then at the 24:15 mark knock counter increased at around 1000-1300 rpm and 70 kPa.
So on the low cam ignition table reduce the ignition. I problem would reduce the six cells at 63 & 74 kPa and 900-1300 rpm by 2-3 degrees, and then blend in the changes by reducing the ignition in columns 88 kPa and up by 1-2 degrees as well.
