Adjustment chip 3.4 for Yamaha

Third generation intelligent chip with the ability to adjust the speed limit of your electric bike

The tuning chip SpeedBox 3.4 allows arbitrary configuration of electric speed limiters. Once the chip is installed, you will be able to see real values such as maximum speed, average speed, daily mileage, and range.

How does SpeedBox 3.4 work?
You can activate the chip SpeedBox 3.4 on the electric bike's display. After pressing the LIGHT button or ↑↓↑↓, the screen will briefly display 99 km/h (62 mph) and from that moment on, you will no longer be limited.

To turn off the chip, press the LIGHT button or ↑↓↑↓ again. The screen will show 25 km/h (16 mph) and the 25 km/h speed limit will reactivate. The electric bike will function as it did before the chip was installed.

We are also prepared for electric bikes that do not have a classic control panel with the Walk button. If you want to control your SpeedBox and lights separately, use the arrow combination ↑↓↑↓ and SpeedBox will activate. You can easily deactivate SpeedBox in the same way. By pressing the arrows in this order, you can turn SpeedBox on and off at any time, independent of the light controls.

To set the maximum speed, you can shift the modes three levels down and then three levels up. The current speed limit will then be displayed. To change the maximum speed, press the LIGHT button briefly or rotate the wheel 360°. The last displayed limit is saved after five seconds of inactivity.

Installation
To connect the SpeedBox chip to an electric bike, we use colour-coded connectors equipped with a key for proper connection, making the chip installation really easy. You can download the instructions or watch videos that will guide you in installing SpeedBox. Removing the chip is as simple as installing it. If you have a connection issue, feel free to contact us.

If you want SpeedBox on a new bike, you must first ride at least 10 kilometres on the bike.
