Hi mate, no not cancel them out but the cc buttons are used when selecting the pre loaded maps. So if you were to hold down the right hand top Accel / res button
and hit the cancel button below once, this is map 1, twice cancel button pressed is map 2 etc etc.You'll know if you're selecting maps as a red led will blink on your dash. Once for may one, twice for map 2.
Unless of course your motors been remapped with one single permanent map which of course makes all the above just a nice little story and nothing more.
Hope it helps a bit anyway.
