Watching the CEL light clear has always amused me.
Timing, throttle position, and RPM are huge numbers when running WOT. You should run them together. That will indirectly (possibly) tell you if you are running lean (possibly getting knock due to timing retard). If your timing doesn't advance through the RPM range, then you are probably getting knock. It's an indirect measurement, but it is usually pretty accurate.
Intake temp and air flow rate might also help you as well (especiallyif you switch from the stock air filter).
I also enjoy watching both the long and short term fuel trims in conjunction with the O2 sensor values. You can keep an eye on those values if you believe you are having O2 sensor problems.
Don't forget that you can save the logs and view them (in detail) on your computer with the Java browser; a very nice feature.
