Unless it's one of those engines that has computer controlled
individual cylinder timing using a knock sensor. Those things will
retard the timing if knocking is sensed, and advance the timing as far
as possible when knocking is not sensed.

Given the fact that most airplane engines don't even have the most basic
advantage, even of vacuum advance, I didn't think that was a very important
factor. g

Good point, but most will only advance within a certain set of parameters.
I doubt if it would be enough to take advantage as much as if you changed it
manually.

Life rules state that there are always exceptions to the rules, right?
