How does the Motorsport ABS adjustable switch work?

The Bosch Motorsport ABS M5 has eleven different control settings, selectable via a switch in the cockpit with 11 different maps with a 12th off position. For the Clubsport ABS kit, it starts with switch position 1 for the most sensitive controller setting (e.g. heavy rain condition).  You can find more information here: https://www.bosch-motorsport-shop.com.au/how-does-Motorsport-ABS-work
