Take your seat off and look at the sticker on the FI unit. Hopefully the tune number is written on there. You should be running 10130. I just had my stock '02 RS updated to tune 10119. Tune "15" refers to the series of FI maps sent to the dealer. They're up to series 16 now, but the tunes for the Sprints haven't changed.

It takes the better part of an hour. $40 would be reasonable.

Dunno... This is my first FI bike.

I know my local dealer hooked an analyser up to my bike and was making manual adjustments. I've read that '02 (and newer) don't have manual CO adjustments any more since they have the new O2 sensor in the exhaust. I asked the tech while he was doing it and he said he can still tweak it manually. The bike is running much better FWIW.

FWIW, I pretty much get 50 MPG doing mostly sporty cruising.

My bike knocks with 89 so I run 93 octane. That was before getting the new tune. Not sure if the new tune would solve that problem or not.
