Includes software and HPA OnePort Flashing Dongle - Requires HPA K04 Longitudinal 2.0T Turbo, HPA TSI Version 2 Manifold, intake (or performance filter) and downpipe.

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.

  • The HPA ONEPort ECU Software can be downloaded here: 


  • Instruction on the ONEPort process can be found here:

*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.*
