A lightweight bluetooth adapter used for running diagnostics through the OBD2 port on your vehicle (or custom application). Paired with the corresponding phone app (Android and iPhone have different options for the apps used). With this adapter you will be able to read all diagnostic trouble codes, computer controlled sensors, and create datalogs for your vehicle. Even 0-60mph tests are supported with this adapter. Additionally, you can use a car mount for your phone and customize a screen to read and display anything that the computer can see, including your exact coolant temperature, rpm, timing, air/fuel ratio, etc. Anything that your ECU (Engine control unit) can read, will be able to be read and displayed by using this adapter.
