About Us

Our hardware solution consists of an adapter cable which has one end that plugs into the USB port of a laptop or desktop computer and another end that plugs into the OBDII diagnostic port of your car. Since our hardware supports USB it is compatible with most computers.


We offer interface cables for all BMW models made since 1988. We currently offer three versions.
Professional Kit: Includes USB-OBD2 interface cable with NO vehicle limitations, Round Diagnostic Adapter Cable for vehicles with a round diagnostic connector, and 50' extension cable
Enthusiast Package: Includes USB-OBD2 interface cable with a 3 vehicle limit
Enthusiast Package with Round Adapter: Includes USB-OBD2 interface cable with a 3 vehicle limit and a adapter for vehicles with round diagnostic connector.
Pictures of each kit can be seen below.
