      1. Take your RTD4 out of the box and plug it into your trucks OBD2 port

       

      2. Go onto your phones app store and download TDN (tune delivery network from HP Tuners)

       

      3. Open the TDN app and create an account using the account option on the main screen

       

      4. After the account is created and signed in select link tuner on the screen in the app

       

      5. Use the code GJMC-8361 to link to us as a tuner, we will get a notification and will add you to our system

       

      6. Select the icon on the bottom right corner which is labeled tools if you are in the main menu and choose setup RTD4 (make sure your phones WIFI and Bluetooth are enabled before proceeding)

       

      7. Follow the prompts on the screen to sync your phone to the RTD4

       

      8. Once the syncing is complete you will need to hit the lighting bolt icon on the bottom of your screen which is the flash selection from your main menu

       

      9. Make sure your ignition is in the run position and follow the prompts on the screen and hit ready to continue
