Message Can KnockSpy1.1 via the stock ECU detect knock that is occurring only at high RPMs under boost/high load conditions. Say at 5000RPM? And, if so, what is the threshold of knock severity that it can detect vs the J&S Safegaurd?

Knockspy obviously cannot, at least in this version, in realtime retard the timing to compensate for that knock the way the J&S can. That part is clear.

I know a fast sampling rate is needed to actively "catch" knock by monitoring the knock sensor directly, but apparently, that is not how the stock ECU operates (you say it checks an intermediary device once per revolution to see if it recorded any knock on that prior rev).
