EZ Lynk Auto Agent 3 DEF Delete Tuner | Duramax LML 6.6L | 2015.5-2016

EZ Lynk DEF delete tuner for LML 2015.5-2016

The EZ Lynk tuner LML Duramax 2015.5-2016 installs custom ECU profiles through a smartphone app and the Auto Agent interface. It is designed for Chevrolet Silverado and GMC Sierra HD diesel pickups with the 6.6L LML engine.

Matching tuning changes DPF regeneration, EGR operation, and DEF/SCR control for the corresponding hardware configuration. Choose engine-only tuning or a package with transmission calibration. This tuner is designed for off-road and racing use.

Why Choose

Vehicle Compatibility

Components

• Auto Agent 3 - OBD-II interface included with tuner packages and Blank; support-only options exclude hardware.
• Custom profiles - vehicle-specific files included with tuning packages; Blank contains no tune files.
• Limited Support - four weeks of access to the supplied tuning profiles.
• Full Support - ongoing access to the supplied profiles without the four-week limit.
• TCM calibration, when selected - transmission file supplied with the transmission-tune option.
• SOTF switch - included with supported switchable tuning configurations.
• Instructions - explain account setup, linking, downloads, and flashing.

Limited and Full Support are alternative packages. Support-only options require an existing Auto Agent 2 or 3. Exhaust, EGR, and CCV parts are separate.

Tuning & Performance

The 2015.5-2016 GM/Chevy Duramax LML tuner for DEF delete loads prepared software through the diagnostic port. Matching calibration removes the corresponding DEF dosing and monitoring requirements, changes engine control, and supports the selected emissions hardware changes.

Software does not physically remove the DPF. Leaving a filter installed after disabling regeneration can allow soot accumulation. Follow the supplied sequence for tuning and mechanical work.

These separate packages provide different engine settings. Zero means stock-rated horsepower with the supplied delete file, not a factory emissions-on profile.

Calibration can adjust fuel delivery and boost control for the intended configuration. Performance and efficiency depend on vehicle condition, supporting hardware, and driving; no fixed gain is guaranteed.

Installation

Instructions accompany the EZ Lynk LML Duramax DEF delete tuner. Prepare a compatible smartphone, the Auto Agent app, internet access, and stable battery support. Create an account, connect the phone to Auto Agent via Wi-Fi, and follow the vehicle-linking procedure.

Custom files are delivered through the app rather than supplied as universal preloaded settings. Download the appropriate profile, then follow the flashing prompts. Allow 30-60 minutes, or up to an hour, for initial setup and programming once files are ready. Mechanical work takes additional time. Our shop provides remote DIY guidance. 

Ordering Information

Most in-stock hardware orders are processed within 1-2 business days. Tracking follows shipment; transit time follows the carrier’s estimate. Support-only orders need no hardware shipment. Profile preparation is separate, and firmware updates are handled through the app.

DEFDelete provides no separate store warranty. Expressly stated manufacturer coverage applies. Eligible unused returns require an RMA within 30 days of delivery. Custom files and programmed products become final sale once calibration, programming, or customer-specific processing begins.
