Interesting read here on another type of knock control

Pre-emptive Feedback knock control PEKC

http://www.romraider.com/forum/viewtopic.php?t=8509

If Unknown Value(Could be delta load or MAFV) Value is greater than 0.25
could also be a throttle % delta and rapid rise in IAT
or
If RPM is greater than 1700
or
If RPM is less than 4400
or
if load is greater than 0.799
or
if load is less than 2.8
or
if primary ol enrichment is less than 1 (AFR 14.7)
or
if coolant temp is greater than 78 degrees c
then
PEKC is active

seems to be where we get "tip in knock"
