Can't find a post on this question. If you have a special tune, (TuneBoy, PCIII, or ???), and you need to disconnect the battery to work on the bike, do you loose the tune? Or is there a battery in the computer to keep any special settings? Or does it default to the stock tune?
Glad someone knew the answer as I wanted to put a special tune in and then have the bike in for scheduled service. They disconnect the battery during parts of the service and didn't want to lose the tune.
