1.3.4 - Knock retard bug?

[MWPau]

Hi all,

I was just going through some logs from yesterday and found this rather odd knock retard issue.

Why has an extra amount of knock retard been added at 738.577 sec? The last knock events were a full 1 second before then.
Why has the amount of knock retard been held for 142 seconds during cruise?

Thanks!

Oh, and while im here...

Can an option be added to only activate knock detection on >X% of TPS or load?
For some reason i get a lot of false positives for knock when i get off the throttle (overrun).
