you might want to take a look at this. although i mentioned in my second post that my response was largely in jest, and admit i just looked this up, i wasn't too far off...

Another killer new feature is their diagnostic device. Dura-Ace has one, too, but it requires you to plug each component in separately and simply blinks lights to indicate a problem. This new one has a very, very nice GUI that loads on your PC (Mac version should be coming soon!) and only requires you to plug it into one shift lever to read the entire system:
The software and device is only intended to locate the damaged part, not diagnose what’s wrong with it. However…
…it does let you customize the way the shifters work. You can pick which button shifts up and down or even swap it so the left shifter/lever controls the rear derailleur. This is a great feature because the system comes set up to operate similarly to the mechanical versions in that the inside lever on the right moves to harder gear on the cassette but moves the front derailleur down to the small ring. I found myself getting them mixed up, and being able to make the same button on both sides control up shifts or down shifts is pretty cool.
Alas, the unit is really intended as a shop tool, and at $200 to $300 expected retail, it’s probably not something most cyclists will have laying around. If you’re loaded, though, it can make for some pretty cool bike geek party tricks. With it plugged into your system, you can tune the shifting and have it simultaneously show you where the derailleur is on screen and move the derailleur on the bike. It borders on creepy making something move just by tapping a button on your computer, but it’s pretty darn cool.
Speaking of adjustments, Ultegra has 30 steps for each gear (versus 24 for Dura-Ace Di2). You don’t need this tool to setup/tune your shifting, it can be done from the bike, too: Simply press and hold the button on the control module until it stays red, then press the shifter to make micro adjustments on one cog. Once you’ve got it lined up perfectly for one cog, it should be adjusted properly for all gears.
