If you were going to use the knock sensor instead of the O2 sensors to
calibrate the mixture, wouldn't you want to LEAN the mixture until it started
knocking, and then slightly richen it from that point? How would you ever get
knocking by continuing to enrich a mixture which is already not knocking?
