MDS Delete PCM Software Service (2015–Present)

The factory Multi-Displacement System (MDS), also known as cylinder deactivation, is designed to improve fuel economy by temporarily disabling four cylinders during light-load driving. While this technology can reduce fuel consumption under specific conditions, many owners prefer to permanently disable the system to achieve more predictable engine behavior and improved drivability.

With our PCM MDS Delete Software Service, we professionally modify the original calibration inside your Powertrain Control Module (PCM), permanently disabling the factory MDS functionality while preserving all other OEM vehicle functions.

This service is suitable for Dodge RAM, Jeep, Dodge and Chrysler vehicles equipped with HEMI engines using the factory MDS system from model year 2015 and newer.

Benefits of disabling MDS

• Permanent deactivation of the factory cylinder deactivation system
• More consistent throttle response
• Smoother engine operation during acceleration and cruising
• Eliminates MDS activation and deactivation transitions
• Improved driving experience, especially on modified vehicles
• Compatible with aftermarket camshaft upgrades that require MDS to be disabled
• Original PCM is retained – no replacement module required

Many customers also choose this service after installing performance components such as upgraded camshafts, lifters or valve train parts, where the factory MDS strategy is no longer desired or compatible.

Important Information

Disabling the MDS software does not repair or prevent mechanical failures associated with worn camshafts, lifters or other internal engine components. If your engine already exhibits mechanical wear, the affected hardware must be repaired or replaced independently. Software modification should be considered a calibration change rather than a mechanical repair.
