DIESELR EZ Lynk Tune Files (2022-2024 Cummins 6.7L)

EZ Lynk tune files for the 2022-2024 Ram 2500 and 3500 with the 6.7L Cummins, calibrated by DIESELR and written for your truck. The EZ Lynk AutoAgent 3 unlocks the factory RAM CM2450B ECM and flashes the tune in the truck, so there is no ECM swap and no downtime waiting on a send-in service.

Each file is built against your VIN and the modifications you list at checkout. Delivery is by email once the calibration is complete.

IMPORTANT: Tuning a 2018+ Ram 6.7L Cummins requires the SGM bypass cable, an OBD-II splitter that works around the factory security gateway so the AutoAgent 3 can communicate: the OBD-II Splitter Unlock Cable (2018+ 6.7L Cummins) (sold separately).

What this replaces

Until now a 2022-2024 truck needed either a controller swap or a mail-in unlock before it could be tuned. Neither step applies here. Order the files, flash with the AutoAgent 3, and the truck runs your calibration.

Your DEF gauge shows the power level

Shift-On-The-Fly tune files give you multiple power levels to fit your build, driving style and goals. You switch between them from the cab with the SOTF switch, bracket and CCV harness, and the DEF gauge displays the power level you have selected. There is no reflash to move between levels.

Precision control

The EZ Lynk platform gives you data logging, parameter and PID monitoring, and fine tune adjustments, so the calibration can be refined as your truck changes.

Transmission tuning

Trucks fitted with the 68RFE receive TCM calibration as part of this package. Trucks fitted with the Aisin transmission require the Aisin transmission tuning package, which is sold separately. Confirm which transmission your truck carries before ordering.
