RANGE DFM (Dynamic Fuel Management) Refresh Module (2021-2024 GM Truck & SUV)

The DFM (Dynamic Fuel Management) Module is designed for late model GM Refresh trucks and SUV's. This innovative device is the first in the market to provide a solution for disabling the dynamic fuel management system in these vehicles. By installing the DMF Module, users can effectively override the vehicle's built-in cylinder management system, allowing the engine to run on all cylinders, all the time! This leads to a better driving experience, and better long term engine reliability.

The 5.3L and 6.2L V8 engines offers in many GM 1500 trucks like the Silverado and Sierra and GM's most popular SUV's like Tahoe, Suburban, Yukon, and Escalade offer excellent power and fuel mileage, but have been plagued by negative side effects from the factory DFM systems for years. Excessive engine oil usage, fouled spark plugs, failed lifters and valve train components and even complete engine failure. Don't let your brand new GM V8 leave you stranded on the side of the road or stuck with an expensive repair bill. Eliminate that worry from life and install the all-new DFM Module today!

This device is a true dual threat eliminating the most frustrating features your brand new truck or SUV's came equipped with, DFM and Engine Auto Start/Stop. By simply plugging this device on to your ECM, both systems will remain inactive at all times, leaving you with the peace of mind your engine will run more consistently without issues or interruption. Just hop in and drive without the worry of cylinders cutting off leaving you powerless or the engine shutting off at every stop sign, creating a hesitation on take-off or killing power to your in-cabin luxuries like A/C and rear entertainment systems.

FEATURES:

• 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 with basic hand tools
• 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 2022.5+ 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 1500 Truck applications may still encounter DFM activation at slow speeds during deceleration 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 illuminate on/off with the button being pressed as it factory, even though the system is always disabled with our module installed at the ECM.
