Opel is the first ever automaker to use an iPhone to display preselected data from the CAN bus (Controller Area Network) for further analysis. All the electronic control units in the vehicle are connected via the CAN bus, or its central system. To get access to CAN bus data, all that Apple smartphone users have to do is to download the OPC PowerApp an application or App from the AppStore for only 0.79 euro.
The application will make its global debut in the Astra OPC with its 206 kW/280 hp output, the sporty leader of Opel’s compact car lineup. The CAN-bus gathers the signals from the various vehicle areas. To date, just highly specialized workshops could access these data by using specialist software. But now, Opel is giving the OPC PowerApp to owners so that they get the chance to get selected, performance-related data.
But even after the car is turned off, the OPC PowerApp can still offer up to 60 different data, such as engine boost pressure, throttle position, lateral acceleration or engine torque. These are easily available in real-time on the iPhone but may also be stored to be looked at later.
For example, racing fans will appreciate its lap-time recorder connected to GPS data. After getting on the Nürburgring track, owners could study and improve their performances on the Nordschleife stretch. Among the factors to be analyzed are the braking points, section speeds, and G-forces inside specific bends.
