Default Non-audible pinging

I noticed that my car will ping on anything below 94. And mind you, I only "hear" pinging on 91, but if it is 93, I don't hear any pinging (maybe my ears are not that great), but, fortunately, I have the knocklink hooked up, so, I would see flashing yellow and briefly-flashing white LED (knock)... However, the det must be small so that it is not audible over the engine noise. For 94 gas, no LED is lighted up at all--only the first green LED is lighted up occasionally (for all 4 of my WOT runs through 2nd, 3rd, 4th, and 5th gear). This is the way it SHOULD be!

So, for those of you who think that their car does not ping, because you don't hear it, you may want to recheck, because the pinging may be small enough that it gets drowned out by the engine noise.

BTW, anyone comming back with a reflash from Subaru yet? Please post results!
