Bully Dog 42214 Cummins Unlock Cable for GT Diesel and BDX Tuner

The Bully Dog 42214 Cummins Unlock Cable is a required accessory for Dodge Ram owners looking to use the Bully Dog GT Diesel or BDX tuner with their 2013–2018 6.7L Cummins diesel engine. This cable enables full communication between the tuner and the truck's ECU, unlocking access to performance tunes, monitoring features, and engine calibration options that are otherwise restricted on newer Cummins platforms.

Key Features:

• Required interface cable for use with the Bully Dog GT Diesel (40420) and BDX tuner on 2013–2018 Dodge Ram 6.7L Cummins
• Simple 4-step installation process guided by on-screen instructions on the tuner
• Enables access to performance, economy, and tow tunes through the GT Diesel or BDX device
• Plug-and-play design for straightforward setup without special tools
• Compatible with Ram 2500, 3500, 4500, and 5500 equipped with the 6.7L Cummins diesel
• Durable construction designed for long-term, reliable use

When used in combination with the Bully Dog GT Diesel tuner, this unlock cable enables significant horsepower, torque, and fuel economy improvements through optimized engine tuning. It is a mandatory companion accessory — the GT Diesel or BDX tuner will not function on 2013+ Cummins applications without it.
