Download Drivers


BOTH Drivers are required. Please make sure to download them both to update your control box


NOTE: The instructions provided use a Polaris 850 as the example. Please be aware that ALL control boxes use the same instructions. They also use the same program, which is named Polaris850_Updater. Don't be alarmed, go ahead and continue through the instructions, which are the same for all makes and models.

ALSO: Some control boxes/computer/tunes require you to disconnect your control box in the middle of the update process. If this happens to you, please follow the instructions. Disconnect the box as requested, but don't forget to disconnect the battery. Then, when prompted, connect the control box THEN connect the battery.
