Map Switching is easily done in a matter of seconds and can be done while the car is running!
To enter Map Switching mode a few conditions must be present
The vehicle must be in the neutral (N) gear position.
The vehicle must not be moving, speed must read 0 mph.
The engine must be running.
If the above entry conditions are met, you can use the cruise control stalk and engine tachometer to navigate map slots
Pushing cancel on the cruise control stalk (towards the dash) will enter map switching mode and display the current map slot on the dash (Map Slot 1 is 1000RPM, Map Slot 2 is 2000RPM, etc…). Map switching mode will exit automatically after 2 seconds of inactivity.
Engine Speed on the tach will temporarily display or sweep to 0 RPM for .5 seconds when initially pushed. This is by design and was made to help distinguish that Map Slot 1 is selected when the car is idling.
While in map switching mode pushing the cruise control stalk up (Set Speed +) will increase the map slot, as displayed on the tach. Pushing the stalk down (Set Speed -) will decrease the map slot.
Inactivity for more than 2 seconds after selecting your map slot will exit map switching mode.
