Dodge Ram 1500 MDS Delete Service – MoPower ECU Programming

MoPower PCM programming disables commanded Multi-Displacement System (MDS) cylinder deactivation on the qualifying factory MDS-equipped applications below. This is a programming service for your controller, not a mechanical hardware removal or engine repair.

MoPower-Supported Applications

Confirm Your Application Before Ordering

Select the exact year and engine and enter the vehicle VIN. Factory MDS equipment and the original engine, transmission and controller configuration must be confirmed. A listed model or displacement does not qualify every trim or transmission. Non-MDS engines, manual-transmission applications without MDS, and unlisted year/engine combinations are excluded. Engine swaps, replacement controllers or modified hardware require prior review. No applications after 2025 are offered.

Software programming does not remove MDS lifters or other mechanical components, repair existing damage, or guarantee prevention of lifter or camshaft failure. Custom engine hardware calibration is not included unless separately agreed.

How It Works

Ship your PCM to MoPower Calibrations, or visit an authorized MoPower tuner. We flash your factory ECU to disable MDS permanently, restoring full-time V8 operation for improved reliability and confidence whether you’re towing, off-roading, or daily driving.
