MT-03/XT660X CO2 Dash mod

Hi im trying to do the CO2 limmiter dash mod to smooth out the bottom end on both my MT 03 and my dads XT660X but i seems that the 2007 model of the XT660X dosent work like the 2006 and lower model years becasue im holding down the select and resent buttons then turning the bike on and off and it just goes on to the normal dash instead of doing in to the diagnostics menu i have found no proof that this can be done on the MT03 but thorght i would try it

is there any other way i can reduce the CO2 restriction because they are so lumpy in the low range

ps the MT03 is a 2006 moddel and it suposed to work on the 2006 XT660X thats y i tried it
