Use live view if you have it. I don't. So I just enduce the ping when I'm close to home and then roll off the throttle for a bit so I can identify the RPM and throttle position when I download the view data. Just go to the closest block in the ADV table that you got the ping and reduce it 2-3 units. Then taper the surrounding blocks higher to lower from top to bottom, and lower to higher from left to right. Exact numbers are not that important, just make the MAP smooth. Save the table and then save the file.
I would also go to a colder set of plugs if you have a high compression engine.
I have the configuration below and am running around 25 degree advance at 2500 rpm. I bet you have ping in the 2100- 2700 rpm at 22-28 MAP. It took going to a colder plug to get rid of the ping on hot summer days. Another suggestion is going richer on the AFR. I am at 12.8 all the way across at 22.5% throttle and above.
