The new firmware offers the ability to switch between two ignition configurations on the fly, via a driver-operated switch.
Enabling this feature is accomplished in two parts.
Wiring option switch
For 3.1.0 controllers, the option input on the Molex connector is used to switch the ignition configuration. The active configuration is selected as follows:
Configuration 1: 0 volts present on Option Port Configuration 2: 5 volts present on Option Port
Note: there are multiple ways to enable the option port; presented are the approaches which require zero to minimal modification to the MJLJ PC board.
3.x MJLJ controller
2.x MJLJ controller
To enable switchable maps on V2.x hardware, you will need to make a small patch on the MJLJ circuit board. Use the following as a guide:
