🔍 What is the HP Tuners RTD4?

The RTD4+ (Remote Tuning Device) is HP Tuners’ latest device, designed to simplify the tuning process—especially for remote tuning customers.

It plugs directly into your vehicle’s OBDII port and allows your tuner (like us!) to send and receive tunes over the internet. No laptop required for you. Just plug in, load the file via the TDN app, and you’re ready to roll.

⚙️ RTD4 Key Features:

• Supports GM (LS/LT), Ford (Coyote), Dodge, and more

• Works with HP Tuners' TDN Mobile App (iOS & Android)

• Logs data and flashes tunes wirelessly

• Easy for customers—perfect for mail-order and remote tuning

🔧 Why These Tools Are Essential for LS and Coyote Tuning

Both the LS and Coyote platforms respond extremely well to tuning—but the factory ECUs need to be recalibrated properly when you:

• Swap cams, intake manifolds, or fuel systems

• Add boost (turbo or supercharger)

• Delete emissions systems (off-road use only)

• Change tire sizes or gear ratios

• Build a swap vehicle (especially with standalone harnesses)

Without proper tuning, your build could suffer from poor drivability, misfires, lean conditions—or even engine damage.

With HP Tuners, you can make sure your engine runs as hard and safe as it should.
