good reading but i wanted something more indepth with respect to how or what signals the ecu uses to retard the timing

[wagonrunner]

i hear yuh.................

speculative guesswork.....................
on the dyno, when an engine is pinging it shows as a lack of rpm signal.
if that's what a knock sensor picks up. the ECU would then retard timing to prevent further knock. as to exactly how a knock sensor picks up that lack of signal, im clueless

the reason for the question is i'm running 16+ psi of boost but ah knocking sometimes on the higher gears or on hills so i wanted a way besides a piggyback to retard the timing
