In this case our selected map are the torque targets for Comfort Mode. We allow each individual gear to be commanded differently, so the map sub-selection pulldown is populated with values 1-6, for gears 1-6. You can also use the - and + to move between these additional maps. On general maps the sub-selection may offer maps by CAM gear and other options.
The toolbar gives you easy access to add, subtract, adjust, and interpolate the current selection. It also allows you to switch to the lambda overlay mode.
