The Software: The Tune Delivery Network or TDN. HP Tuners’ new Tune Delivery Network (TDN) is the fastest and easiest way to share calibration files and access information. You are invited via the TDN portal to instantly share vehicle read files and access datalogs for remote diagnostics. The free TDN app syncs with an RTD/RTD+ via Bluetooth, removing the laptop from the read/write phase of flashing your vehicle. TDN makes it possible to reach more customers than ever.
Android and iOS app available for free download:
