Hi, i look at threads alot and im kinda new to the tunning stuff, and i see the word knock alot, and i was just wondering what that means?????

" Knock, also known as preignition or detonation, is a damaging condition brought on by excessively advanced ignition timing, lean air-fuel mixtures and/or low octane or poor quality gasoline."

Detonation when the air/fuel mixture in the cylinder explodes, instead of burning rapidly.
(To be really technical, detonation is when the flame front moving through the cylinder exceeds
the speed of sound.)
