OK Bear with me here. Im about to ask a really dumb question, possibly
the dumbest question ever asked... You may actually become dumber just by
reading it! anyway...
If a knock sensor by definition senses pre-ignition (aka ping)..
..let me know when I go astray here...
A 'ping' is the predetenation of fuel,..it is igniting BEFORE the spark
arrives (potentialy causing damage blah blah blah...)
So if a knock sensor detects a ping, it will retard my ignition timing...
Now if Im not mistaken, my whole problem is that it ignited too early,
why retard it? What does it gain? Am I missing something here? Who
invented liquid soap and why? (Better off dead, John Cusak)
TIA and sorry for my stupidity...
