[QUOTE="DanPromote, post: 141220, member: 1834"] No it does not, a knock sensor's function is to warn the ecu when engine knocking occurs to prevent detonation. The ecu, when it gets the reading from the knock sensor then will compensate by retarding the ignition timing or increase fuelling until engine knocking is eliminated. When an ecu is remapped, it is usually running on slightly lean fuel maps which is fine for n/a cars. You will notice better fuel consumption as well as more power on the whole range of power/torque curve. [/QUOTE]
