Installation steps

Disconnect power. Turn the scooter off and disconnect the battery before opening the trunk.
Remove the trunk. Unscrew the four trunk screws and lift the trunk so the original controller is accessible.
Disconnect the original controller. Remove the power plug, controller plugs and five coloured phase cables. Photograph the original cable positions first.
Install the upgrade controller. Secure the controller and reconnect every plug and phase cable firmly. A larger controller may use two mounting screws instead of all four.
Connect the adapter. Connect the supplied two-headed adapter exactly as shown in the product instructions: the controller side goes to KZQ and the scooter power connection goes to CAR.
Test before closing the trunk. Reconnect the battery, test the dashboard and riding modes, then finish assembly.
NIU N1: the N1 installation also uses the supplied 6-pin Hall adapter.

Troubleshooting

The READY light appears immediately and the dashboard cannot change modes

Recheck the two-headed adapter. It may be connected in the wrong direction or may have come loose while reinstalling the seat.

The scooter powers on but does not drive normally

The controller parameters may not match the scooter. Stop testing and contact us for the correct model settings.

Error 11 appears

Check the configured battery voltage. This can happen when, for example, a 48V scooter is configured with 60V settings.

The screws are difficult to remove

Use the correct screwdriver bit and avoid excessive force with an electric screwdriver, which can strip the screw head.
