EZ Lynk Auto Agent 3 DEF Delete Tuner | GM/Chevy Duramax LML 6.6L | 2011-2015

EZ Lynk DEF delete tuner for Duramax LML 2011-2015

The 2011, 2012, 2013, 2014, 2015 GM/Chevy Duramax LML DEF Delete Tuner combines vehicle-specific calibration with a wireless Auto Agent 3 interface for Chevrolet Silverado and GMC Sierra HD pickups. It updates engine control strategies to match a modified DPF, DEF/SCR, and EGR system.

Correctly matched tuning and mechanical parts eliminate regeneration associated with the removed filter and can improve throttle response. Choose a device with a support package, a support pack for an existing interface, or a BLANK device without tune files.

Why Choose

• LML-specific calibration - prepared for the supported engine, controller, and modifications.
• Cloud-delivered files - access supplied ECU profiles through the Auto Agent app.
• Wireless programming - use a compatible smartphone for installation and monitoring.
• Flexible support access - select four-week or Full Support access to the supplied tunes.
• Multiple purchase options - buy hardware and calibration together or select only what your setup requires.

Vehicle Compatibility

This package fits the listed LML pickups. Submit the VIN, transmission, drivetrain, tire size, and modifications. Commercial configurations require their own profile.

Components

• Auto Agent 3 interface - supplied with a TUNER or BLANK option. Connects the truck to the mobile app.
• OBD-II connection cable - connects the purchased interface to the vehicle’s diagnostic port.
• Vehicle-specific ECU profiles - included with the selected support package and delivered digitally.
• Four-week or Full Support package - provides four weeks of tune access or indefinite access to the supplied profiles.

Support Package Only options require an existing Auto Agent 2 or 3. The BLANK option supplies hardware without calibration files.

Supported SOTF profiles require a compatible switch, arranged separately. Mechanical exhaust parts and an EGR Delete Kit are separate purchases.

Tuning & Performance

The EZ Lynk Auto Agent 3 DEF Delete Tuner for LML Duramax 2011-2015 installs custom calibration through the diagnostic connection. It changes ECM strategies associated with modified emissions equipment, while replacement hardware provides the physical exhaust configuration.

DEF/SCR removal eliminates fluid dosing. DPF removal eliminates the filter that normally requires regeneration. Flashing alone does not remove hardware; disabling regeneration with the DPF installed can cause soot accumulation and restriction.

Calibration options can include:

Available settings follow the selected ECU profile. SOTF requires compatible calibration and controls; a blank device does not provide switchable tuning.

Revised fueling and boost control can unlock additional performance. The best setting respects workload and mechanical limits. Actual horsepower, economy, and reliability depend on vehicle condition and installation quality.

Installation

Using the EZ Lynk Tuner for LML Duramax requires a compatible smartphone, the Auto Agent app, internet access for downloads, and stable battery support.

1. Create an account and register the device.
2. Submit the VIN and vehicle configuration.
3. Connect through OBD-II and join the interface’s Wi-Fi network.
4. Link to the assigned technician and download the correct profile.
5. Follow the programming prompts and prescribed hardware-installation sequence.
6. Verify operation and check diagnostic codes.

Use the application-specific LML switch instructions for SOTF controls. Keep the device connected for live monitoring; it can be disconnected after programming when monitoring is unnecessary.

Flashing takes several minutes; setup and checks add time. Experienced owners can perform guided programming, while a diesel shop can assist with mechanical work. DEFDelete provides remote setup guidance.
