That's only true to a point. The knock sensor will retard timing from a base
reference when knocking is detected. It will not make the timing more
aggressive than what it was designed for. That is, if the programing was
designed around the use of 87 octane and the sensor does not detect knocking
with it, 92 octane will not do anything to improve performance.
