You should be far more disturbed that your ECU isn't bothering to cut wgdc when you have negative lde

Start with that.

BTW KFDLULS is for overboost protection, not throttle cut, which happens at 200mbar

Finally, a bit of timing pull will not trigger a "continuous knock" condition.

The FR covers both of the above

Speed sensor issues can trigger all sorts of problems.
