I know that the actual number shown doesn't correlate to anything, but from what I've seen if the number doesn't go up more when going higher on timing, leaner AFR, more boost, or higher outside temperatures -- you should be good knock wise. Especially since OBD2 logging sucks so much.

The stock ECU will normally retard timing from extremely faint knock before add-on knock devices can even pick anything up, 4G63's do not knock all that loud compared to some other motors. You can log knock on 2Gs nowdays. E85 can be so knock resistant though that you can reach a point where you don't gain power from leaner or more timing, yet it might not be knocking.
