Got questions? We’ve got answers.

No. There is no vehicle limit. You can use the dongle to manage and flash as many compatible vehicles as you like. The appropriate tuning software must be purchased separately for each vehicle.

No. Each tuning software purchase is valid for one vehicle only and is permanently assigned to that vehicle. The tutorial walks you through the assignment process step by step.

No. Once flashing is complete, the software is stored directly on your vehicle’s control unit and the dongle can be removed. We recommend unplugging it from the OBD2 port when it will not be used for an extended period.

Make sure the vehicle battery is sufficiently charged, ideally connect a suitable battery charger, and switch off unnecessary electrical loads. Follow the application’s instructions throughout the entire process.

No. Do not switch off the ignition or your device, and do not disconnect anything. Interrupting the process can result in an incomplete write and may damage the control unit.
