Abnormal combustion does that. I just don't see how it makes sense to build engines for fuel that isn't available. If it was tuned right in the first place there would be no need to retard. Timing, to me, has always been something you sneak up on, work up to it carefully. Not something you pile on way too much of then compensate for after it has already allowed preignition or detonation.
