93 octane to 87 to 93 - Timing question

[TTA89]

Ok, I admit it! Gas is getting expensive so I have been putting 87 in for my 60 mile a day commute. I'm going to head to the track in a few weeks so I'll start running 93 octane again.

Do I need to disconnect the battery or anything to get the timing to come back or will it figure it out after a few WOT blasts with 93 octane?

nope i did this the first winter i had the car, just run it low, and fill her up. After about a 100 miles or sooner the car will have adjusted the few trims accordingly
