The ONEPort, which is basically an OBD-II to USB device, allows the end user to extract critical ECU ID information, which can then be e-mailed to us for analysis and modification. Once a specific tune file is completed here in our offices, the updated file is then e-mailed back to the customer for upload into the vehicle.

Each ONEPort device can only be paired to an individual VIN number, and therefore is owned by the user once purchased (it is not a loaner tool). However, the ONEPort can also be used for DSG / S-tronic programming in the same vehicle, if applicable.
