HP Tuners RTD (RTD+ Gen 4) — Remote Tuning Device for Diesel & Gas Trucks

The HP Tuners RTD (Remote Tuning Device) is the easiest way to get professional, custom tunes loaded onto your truck — without a laptop and without a trip to the shop. Plug the RTD into your OBDII port, pair it with the free TDN (Tune Delivery Network) app on your iOS or Android phone, and your tuner sends calibrations straight to your vehicle, anywhere you are.

If you've been comparing the HP Tuners RTD vs MPVI3, here's the difference: the MPVI-series is built for tuners writing calibrations on a laptop, while the RTD is purpose-built for the remote-tuning customer — it receives and flashes the tunes your shop builds for you, no software or PC required.

How the RTD Works

1. Plug the RTD into your truck's OBDII port.
2. Download the free TDN app and connect over Bluetooth / Wi-Fi.
3. License your vehicle with credits, then receive and flash your custom tune — right from your phone.

Why You'll Want an RTD

• No laptop required — flash and switch tunes from your iOS or Android phone via the TDN app.
• Remote tune delivery — get pro-built calibrations sent to your truck without a shop visit.
• RTD Gen 4 coverage — supports 300+ HP Tuners vehicle controllers across diesel and gas platforms.
• Onboard Wi-Fi — faster tune transfers and streamlined remote diagnostics (Wi-Fi expanding with future firmware updates).
• Read & clear DTCs — pull and clear diagnostic trouble codes instantly from your mobile device.
• Standalone data logging — capture logs for your tuner without ever opening a laptop.
• Tune security — your calibration is locked to the device; customers can't open or edit it in VCM Editor.
• Pro-grade diagnostics — fully compatible with VCM Scanner and the HP Tuners Pro Feature Set.

Before You Buy — Credits & Compatibility

Like all HP Tuners hardware, the RTD uses credits to license each vehicle (controller) before writing a tune — licensing is handled right in the TDN app, and credits are sold separately. The RTD Gen 4 supports over 300 controllers across popular diesel and gas trucks. Not sure if your truck is covered?
