From an earlier post in this thread I didn't think the reset in tuneedit worked! I've had my battery off for a few weeks (under my desk because of the cold), so wouldn't the memory on the clocks have reset anyway?
When I went out for a ride after doing the tune everything except the odo had reset to zero, except the clock which re-started at 3:43! As you say, the bike thought it has no fuel (had 2 bars before I started the tune download) and took a mile or 2 to come up to 1 bar and 15 left to go!
BTW the tune (yours!) feels really smooth. I'm going to leave it as is until I can get a good couple of weeks solid riding in, so I can get used to it, before I start to fiddle with it, if indeed I feel I need to.
