Knock detection

The uncontrolled explosions cause structure borne vibrations (causing the characteristic pinking or pinging sound) which are detected by knock sensors mounted on the exterior wall of the engine block. Knock is a problem, particularly in lean burning or high compression engines, as it can create excessive combustion chamber pressures.The knock detection routine begins at 0xD00. The first section is where detection actually happens. First, we load the current knock threshold value for the cylinder that fired in the previous cycle (7Ah), then we check if that threshold is higher than the maximum (45h), and if so, overwrite it with maximum value: The uncontrolled explosions cause structure borne vibrations (causing the characteristic pinking or pinging sound) which are detected by knock sensors mounted on the exterior wall of the engine block.
