E46 ECM Unlock — No Send-In Required

The factory E46 ECM found in 2019–2022 LM2 Duramax trucks can be unlocked and flashed directly through EZ Lynk using Dieselr-developed tuning files.

What this means:

• ECM unlock and tuning completed on-vehicle
• No removal or shipping of the ECM
• All flashing handled through the EZ Lynk AutoAgent 3 device
• Files delivered and managed through the EZ Lynk mobile app

This is the cleanest way to tune an LM2 platform.

Dieselr LM2 Power Levels

Dieselr tuning for the LM2 mirrors the same Level 1 (+0HP) and Level 2 (+20HP) power strategies available on other supported platforms, focusing on usable gains and controlled drivability.

Calibration priorities include:

• Smooth power delivery
• Predictable throttle response
• Clean integration with factory systems
• Real-world drivability over peak numbers

This is tuning built for daily-driven LM2 trucks — not experiments.

Support Package Options

This product is offered in two variants:

4-Week Support Package
Ideal for customers who want short-term tuning access and setup support.

Lifetime Support Package
Includes ongoing file access and support, with tune files auto-shared through EZ Lynk as updates or revisions are needed.

Both options use the same Dieselr-developed tune files and EZ Lynk delivery system.

EZ Lynk AutoAgent 3 & Mobile App Delivery

All tuning is completed using the EZ Lynk AutoAgent 3 device, with file delivery and flashing handled through the EZ Lynk mobile app on the customer’s smartphone.

No laptops.
No cables running through the cab.
Everything managed from the phone.
