Upgrade your Alltrax controller with precision control and on-the-fly performance adjustments. The Alltrax FN-Key Function Box allows you to instantly switch between two programmable driving modes and fine-tune throttle response or regenerative braking without connecting a laptop or Bluetooth module.


Features

  • Two-Mode Key Switch: Toggle between two custom performance profiles (such as "Street" and "Performance" or "Normal" and "Tow") using the included keyed selector switch.

  • Adjustable Performance Dial: Built-in potentiometer lets you fine-tune speed limit, throttle response, or regenerative braking strength directly from the dash.

  • LED Mode Indicator: Red and green LEDs clearly indicate which mode is active.

  • Plug-and-Play Installation: Includes a 6-foot cable with 4-pin connector that plugs directly into the controller’s FN port—no cutting or splicing required.

  • Secure Access: Keyed operation prevents unauthorized access to high-performance settings.
