Remote updates

Bosch regularly releases new firmware versions for its motors, which may affect compatibility with our products or increase the risk of tuning detection. Therefore, we strongly recommend not performing these updates in order to ensure the continued full functionality of our products.

However, we continuously respond to these changes by updating our firmware. One of the biggest advantages of the B.Tuning version is the ability to update your SpeedBox directly via the SpeedBox App – without the need to purchase a new chip, even if you have already updated the system.

If we have tested and confirmed compatibility with the latest Bosch firmware and your chip includes the so-called Factory Bootloader (the icon is marked on the back of the chip), you can safely update your SpeedBox via the app.

Installation

Installing the device is easy and intuitive. Choose the option that suits you best – a video guide, a printed manual, or a detailed step-by-step picture guide.

Video guide

You can find a detailed installation and tuning activation procedure on our YouTube channel

Printed manual

Inside the product package you will find a printed manual including a wiring diagram for connecting the chip to the motor

Step by step

The illustrated guide will walk you through the installation step by step — from removing the motor cover to the test ride. Each step is accompanied by photos and clear explanations.
