Good point. High octane burns slower so more advance is required, all
else being equal.

Remember
that ED is using 100LL. Would that make a difference?

I have to wonder if there was something wrong with the old engine or

is about the only thing that can make a basically healthy engine give such
higher fuel burn. (retarded ignition timing). Anyway, glad you
found the extra efficiency & power. Even with a bit more weight
& drag, your -6 should not have been that much different than my
-4.

I would expect ignition timing to be advanced right through 30-35
degrees with LOP operation.
It would appear as very high octane fuel to the rotary. If you notice
EGT go up slightly with leaning, that is the cause.
