Is there a way to speed up GM.ASPARK? I'm still not at High Octane Spark Curve after 2 tanks of High Octane, both tanks were run very low so I'm sure it's 99% High Octane.

I don't like to force the High Octane Spark table to low octane as I may loose knock prevention although I do this is tuning while I can watch, I don't like to give a vehicle back and then maybe get a bad tank of fuel or?
