We use original connectors for the production of SpeedBox chips, so that the installation of the chip is really easy and the connection is correct. We have prepared detailed instructions and recorded videos thanks to which every customer can install the SpeedBox themselves. Disassembling the tuning chip is just as easy as assembly. If you have any problems with the connection, please contact us!
The activation/deactivation of the tuning should always be done before driving and not while driving. Options for the SpeedBox app: Tuning control Setting the maximum auxiliary speed Save and display driving data Possibility to hide tuning Engine diagnosis
