USER INTERFACE

Once initial device setup is complete, the TDN home screen will be displayed. This is the initial screen that appears whenever you start the app. 

NAVIGATION BAR

The primary feature of the home screen is the navigation bar along the bottom of the display.  A smaller version of the navbar can be found along the bottom of many of the other screens in the TDN app.

The individual buttons in the navbar have the following functions:

                                                                            Returns to the home screen.     

                                                                           Displays the TDN Account Login screen. HP Tuners accounts can be created and modified on this screen. See Account Creation and Configuration.  

                                                                            Displays the Tunes screen. From this screen, you can read your car’s current tune, send it to your tuner, and apply tuning files received from your tuner. See Reading and Writing Tunes.

                                                                            Displays the DTC screen, which allows you to read Diagnostic Trouble Codes (DTCs) from the vehicle. See Reading Diagnostic Trouble Codes.

                                                                        Displays the Data Log screen, which gathers live performance data from the vehicle. This data may be useful to your tuner in creating a new tune, or in validating a preliminary tune. See Data Logging.

                                                                            Displays the Setup / Tools Menu, which contains a handful of additional utilities and informational resources. See The Setup / Tools Menu.
