I got a copy of the shop manual for the '04 R1 the other day, and it has some interesting tidbits in it (although this stuff may have been around in previous generation R1s as well...)

First off the LCD display has a diagnostic mode which is accessed by holding both the select and reset buttons down while turning the bike on. This mode can display a long list of OBDII-style info right on the LCD. Amusingly, one of the fault codes for this mode is listed as "motorcycle has overturned". Don't think you'll need a computer to tell you that!

For you anal dyno tuners out there, there is also a display mode that allows you to precisely adjust the air/fuel mixture on a cylinder-by-cylinder basis. Could be useful, in conjunction with a CO detector, to attempt to set the ideal stoichiometric mixture.

Interesting how deeply computerized bikes are these days.

Being able to adjust FI has been done since '02. Unless you have access to an O2 analyzer, I wouldn't suggest it! Yes, you can adjust it, but it does it to the ECU and if you mess it up, your screwed! At least with a power commander, you can unplug it and go back to stock settings to get home. This is for only Knowledgeable people familiar with this system.

I think it only allows course limited adjustments?
