You're off to a good start, knowing what's going on is more than half of the story...
At WOT, your HO2S11/21 voltages are a little low at 860-880mV meaning it's lean, you want to observe these being something like 930-950mV (see next paragraph), this could be the reason for the knock you're seeing;
you can fix this using a WBO2 sensor to tune the VE table and MAF table and then setting the PE vs RPM table to get richer at WOT (and verifying using the WBO2S);
use the WBO2 to make changes; use the HO2S11/21 voltages for observation only.
Other ideas:
display MAF and MAP in metric (easier numbers, at least for me anyway);
in a log chart, display as many PID's as you can, more info = better analysis.
make your pictures a little bigger.
