Performance monitors are a cool tool to monitor vehicle performance in real time and get important information about engine and vehicle characteristics. In this blog article we show what you should pay attention to if you want to retrofit a performance monitor in your vehicle. We also explain the different connectivity options that are available to you and introduce some vehicles that may even have a performance meter unlocked at the factory.

Retrofit performance monitor

  • Choosing the right performance monitor: Before you start retrofitting, you should consider what information you would like to see displayed on the performance monitor. Be sure to choose a device that meets your needs and is of course compatible with the vehicle. Some monitors only have basic functions, while others provide detailed data on engine power, torque, fuel consumption, boost pressure, G values ​​and much more.

  • Connection options: Most performance monitors can be connected via the vehicle's OBD-II (On-Board Diagnostics) socket. This is a standardized interface that has been present in almost all vehicles since the mid-1990s. Connection via the OBD-II socket is uncomplicated and allows access to a wide range of vehicle data. Make sure the performance monitor you intend to purchase is compatible with the vehicle's OBD II standard.

  • Factory unlockable performance displays: In some cases it is possible to unlock a hidden performance display in the vehicle from the factory. This is the case, for example, with the VW Golf GTI Performance (MK7) or the Seat Leon Cupra. To unlock the ads, you usually need special software like VCDS (VAG-COM Diagnostic System) or similar. The software allows you to access the vehicle control unit via the OBD-II interface and activate or deactivate certain functions. Note, however, that unlocking such features may potentially affect the vehicle's warranty.
