Question about this product?

We're happy to help.

The Duramax LM2 all-in-one tuning EZ Lynk kit from Dieselr is a complete, platform-matched solution for owners who want a controlled, predictable setup on the 3.0L GM Duramax LM2 platform. This kit removes configuration guesswork by combining Dieselr-validated tuning with the correct supporting hardware—assembled to work together under real operating conditions.

This package is built around Dieselr EZ Lynk E46 tune files, delivered through the EZ Lynk AutoAgent 3. The tuning is platform-specific for 2019–2022 GM 1500 trucks equipped with the 3.0L Duramax LM2, focusing on refined drivability, managed torque delivery, and long-term reliability.

The kit allows you to configure supporting hardware based on your build, including Dieselr Cat & DPF race pipe options and the Dieselr EGR upgrade kit, ensuring the calibration and physical components remain aligned.

This is not a generic bundle. It is a Dieselr-built system intended for customers who already understand the platform and want a solution that works the way it should.

UPDATE!!

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.
