Do you know how they can tell?

Does anyone have first-hand experience with their tune or even their reversed tune being detected by a BMW dealer? Especially on the E8X and E9X platforms.

While on the subject, for 1 M Coupe, the M steering wheel button seems to toggle between 2 different throttle/boost mappings. So could one change only one of these mappings and leave the other one intact?
