Map Slot selections will persist after keying off.
e.g. If you shut the car down on map slot 2, it will remember the map slot indefinitely and resume in map slot 2 when you restart the car.
Map Slots are often made with different octanes in mind. Always pay close attention to which map slot you are in when changing fuels. Never run a map slot designed for high octane fuel with a low octane fuel in the tank! Higher octane fuel is generally more stable and resistant to knock. Higher octane fuel allows for advanced ignition timing and leaner lambda targets than lower octane fuel. Engine damage may occur if map switching is used improperly.
Checking Your Map Slot
You can always check the map slot simply by pushing +speed/set on the cruise control stalk (towards the dash) when the vehicle is stopped. You can not check your map slot while cruise control is armed and actively controlling vehicle speed.
