Ahh there is another setting for the gearbox
It is at the back of the gear lever, you can see it in the pics here with 3 horizontal lines on it

Ohh I couldn't find a pic in that thread of the dash showing the display but it is in the middle of the tacho and speedo in the M6, I assume it would be the same in the M2. There is a picture here of the car with it in the slowest shifting mode near the end of the UK press pics.
