There is also another way to alter the CO targets for idle and under load
Just by the XC-1 dealer kit

Somebody tested this on his 690sm

We played around with some changes to the CO target under load. The software works with a multiply factor so you don't really see the actual CO target stored in the ECU. Only the mulitply factor and that can be mouse-click changed with + or -. It looks like the changes work on the trim table used in 'open loop' during acceleration and/or a changing throttle. This is when the ECU doesn't look at the data from the Lambda/O2 sensor but to the 'hard' data stored in the fuel- & trim-table(s). During (near) constant conditions when cruising or gentle/slow accelaration the system enters 'closed loop' mode and then it looks also to the O2 sensor and the ECU will work to adjust the mixture to Lambda 0.95. Which is fine.
Again, this is how it seems to work. But in any case the results are clear. We adjusted the CO target under load a little richer on four different 690s in our group with identical results. Much smoother running in transition (idle to throttle) and at small throttle openings. Better throttle response and pickup in the low-end and midrange. Jerky- or hairyness at small throttle openings when riding through traffic or feeding the throttle coming out of corners is gone. Amazing...
A quick testrun on a dyno showed that the air-fuel graph is identical in shape but richer over the entire rev range. So it's richer or leaner everywhere, nothing else. No fine tuning of certain areas or throttle positions. This function allows a dealer iron out possible FI glitches, NOT to 'tune' a bike for a special exhaust, engine mods, airbox mods etc. That still requires tools like a PowerCommander, Rapid Bike, Tuneboy etc.
