OpenBimmer

OpenBimmer turns a Bluetooth LE OBD adapter into a live dashboard, data logger and diagnostics tool. It is built for BMW turbo engines (N54, N55, B58, S55, N13, S58, S63) and works with any car that has an OBD-II port.

WHAT YOU NEED
An ELM327-compatible Bluetooth LE adapter, for example Vgate iCar Pro BLE, Veepeak OBDCheck BLE, vLinker BLE or OBDLink CX. No adapter yet? The built-in demo adapter lets you try everything.

OpenBimmer reads standardised OBD-II data and never writes software to your car. Never use the app while driving. OpenBimmer is an independent community project and not affiliated with BMW AG. BMW and the engine names are trademarks of their owners and are only used to describe compatibility.
