HPA OnePort flashing device is a compact OBD II dongle that gives you the power to flash HPA software tunes to your ECU quickly and easily.

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.
