Tuning the 900 using the dashboard buttons

[Oldgit59]

Hi all. I'm a new owner of a 2010 9er with Mivv carbon cans and maybe no cats. I did the air flap disable mod using wire 8 on the ECU. Better but not great. I increased the CO from 14 and 19 in steps up to 90. Again better but not great. Header pipes have slight blueing. Spark plugs checked completely clean, no sandy colour. If the fuel mix that is indicated by the plugs colour is controlled by the ECU and the CO adjustment has no effect how can the mixture be improved to get the right plugs colour? Frits44 what tool do you have to measure the exhaust gas %? Cannot believe this bike has so much problems in this area from a top manufacturer. Thanks Tony
