Range DFM Disabler Module | Fits 2021-2024 GM SUV and 2022.5-2024 GM 1500 Truck

Eliminate the frustrating DFM and Engine Auto Start/Stop features in your 2021-2024 GM SUV or 2022.5-2024 GM 1500 Truck with the Range DFM Disabler Module. This device keeps both systems inactive at all times for a more consistent engine performance and uninterrupted driving. Say goodbye to powerless moments, hesitation on take-off, and loss of in-cabin luxuries.

• Disables Dynamic Fuel Management (DFM) and Engine Auto Start/Stop systems
• Smart inline technology integrates seamlessly with the ECM
• Allows a true ‘Return to Stock’ status when removed with no trace for worry free dealer services
• All-time V8 mode means better power on demand, a more consistent driving experience, reduced engine and valvetrain wear, and improved long term engine reliability
• Enjoy that V8 rumble and avoid unpleasant exhaust notes and drone from running in cylinder deactivation mode
• Plug-and-play installation can be completed in minutes
• 49-State Emissions Compliant, 50-State CARB EO Pending
• First to market product for Global B and Refresh model support
• To confirm your 2022 model truck is compatible with this unit, check your VIN. The 12th digit in a Refresh model must be a '5' or higher
• This device is compatible with ALL 2023 and 2024 truck and SUV models with the 5.3L and 6.2L engine
• Some applications may still encounter 0-Cylinder Mode while coasting when 0% throttle input is detected at the ECM
• We do not control the in-cab Auto Start/Stop switch on the dash, so it will still iluminate on/off with the button being pressed as it factory, even though the system is always disabled with our module installed at the ECM.
• Made in USA
