PLEASE NOTE: Vehicle ECUs vary in the amount of sensors supported. This app can’t show you something, that is not provided by your car. The Engine needs to be cold, so don't do this after a long drive or nothing will happen. Make sure all electrical items (the A/C, the audio, the lights, etc.) are off. Attention "bad" adapters! We faced the problem, that some adapters (often cheep Chinese clones), can’t connect to the smartphone or the car. Some of them can even make your car engine work unstable, often lost connection, increase time lag when reading data. So, we recommend you to use genuine ELM327 or recommended adapter brands.
