CO2 question
 

Hi all, I just entered the co mode after the diag screen and it comes up with C1 then I press select and reset again and it comes up with 21.

So the dash says C1 21 does this sound right

Its a 2010 XTX with mtc cans, baffles out

Also why does my bros 2004 model go to C1 or C2 my 2010 only has C1

21 is about right.

CO1 = single cylinder Co adjustment
CO2 = 2 cylinder as the XT660 ECU's hardware is used on the TDM as well.

2004 to 2006 same hardware as TDM, 2007 to present different hardware not used for TDM.

excellent thanks kev.

So I tried adjusting it to 15 just to see what happens then adjusted it to 30 but there is no difference on any of them.

I dont know what to do, and i dont have the money at the moment to buy any mods

Co1 only adjusts part throttle A/F ratio, if you want to adjust the A/F ratio above 2 to 5% you will need a fuelling device.

Your bike can safely run with the cans, if you fit filters + cans I would fit a fuel mod.
