	===Switchable Ignition ~~maps~~===		===Dual Switchable Ignition Configurations===

			The Megajolt Lite Jr. supports on-the-fly switching between two Ignition Configurations. Each independent configuration includes the entire ignition map and all controller options (Engine type, User-defined outputs, Rev limit and Shift light settings).

			====Enabling Switchable Ignition Configurations====
			To use this feature requires it to be enabled in the Controller's firmware. Open the ''Global Configuration Options'' dialog by clicking the 'Options' Menu and then selecting 'Global Controller Options'.

			[[image:mjlj_operation_guide_global_controller_options.png]]

			The Software will attempt to read the Global Controller Options when you open the dialog, so ensure the Controller is powered on and connected to your computer.

			Click the check box 'Enable Dual Ignition Config', and then click 'Write Options'. This will immediately '''flash''' the Global Configuration data to the controller's flash memory.

			====Enable hardware switch====
			Switching between ignition configurations requires wiring the option switch to the Controller. Refer to the [[MJLJ_V3_vehicle_installation_guide#Enabling_Option_Switch_.28For_MJLJ_firmware_.3E_3.1.0.29\|Installation Guide]] for more information.

			====Configuration software behavior====
			Once enabled in the controller, the software will alert you when the controller switches to a different ignition configuration. You can define how the software reacts to the switch:

			* '''No Action:''' The software only alerts you of the change.
			* '''Prompt to read configuration:''' The software prompts you to read the Ignition Configuration the controller was just switched to.
			* '''Auto-Read configuration:''' The software automatically reads the Ignition Configuration the controller was just switched to, discarding any in-progress changes made in the software.

			====Important Usage Notes====
			The switchable Ignition Configurations can be thought of two controllers in one; or, one controller with two different personalities.

			This means you must manage the two Ignition configurations independently by separately reading, writing and '''flashing''' the Ignition Configuration as appropriate.
