Range Technology DFM Disabler Module for GM SUV / GM 1500 Truck

The DFM (Dynamic Fuel Management) module was developed specifically for newer GM Refresh trucks and SUVs. This innovative device is the first on the market to provide a solution to disable the Dynamic Fuel Management system in these vehicles. By installing the DFM module, users can effectively bypass the factory cylinder management system, allowing the engine to run on all cylinders at all times! This ensures a better driving experience and greater engine reliability in the long term.

The 5.3L and 6.2L V8 engines found in many GM 1500 trucks such as the Silverado and Sierra, as well as the most popular GM SUVs such as the Tahoe, Suburban, Yukon and Escalade, offer outstanding performance and fuel efficiency. However, for years they were marred by negative side effects of the factory DFM system: excessive oil consumption, sooty spark plugs, faulty valve lifters and valve train components, and even complete engine failure. Don't let your new GM V8 leave you stranded or incur expensive repair costs. Relieve yourself of this worry and install the brand new DFM module today!

This device is a true dual solution as it disables two of the most frustrating features of your new truck or SUV: DFM and the automatic engine start/stop function. By simply plugging this device into the engine control unit, both systems will remain permanently disabled, keeping your engine running smoothly without problems or interruptions. Just get in and drive away - without worrying about cylinders shutting down and missing power or the engine stalling at every stoplight, delaying startup or affecting your interior features like air conditioning and entertainment systems.

On some vehicles, the 0-cylinder mode may remain activated when rolling, even if this product is installed. During extensive testing, it was found that completely disabling this feature leads to undesirable driving characteristics and safety concerns. Deactivating 0-cylinder mode while taxiing resulted in a noticeable decrease in fuel efficiency as the engine continues to inject fuel and the injectors remain active. This can also cause an unpleasant driving sensation when decelerating, as it feels as if the vehicle is accelerating slightly even though there is no throttle input. This requires harder braking, especially when towing or on long downhill stretches, which can lead to undesirable driving situations.

Functions:

• Deactivates Dynamic Fuel Management (DFM) and the automatic engine start/stop function
• Intelligent inline technology integrates seamlessly with the ECM
• Enables a genuine "factory condition" on removal - no traces for worry-free workshop visits
• The permanent V8 mode ensures better performance on demand, a smoother driving experience, less wear on the engine and valve train and improved long-term engine reliability
• Enjoy the full V8 sound and avoid unpleasant exhaust notes and roaring thanks to the cylinder deactivation mode
• Plug-and-play installation in just a few minutes
• To check the compatibility of your 2022 truck with this device, check your VIN: the 12th digit must be a "5" or higher
• Compatible with all 2023-2025 truck and 2021-2024 SUV models with the 5.3L and 6.2L engine
• In some applications, 0-cylinder mode may still be active when rolling if the ECM detects a 0% throttle position
• The device does not control the auto start/stop switch in the dashboard - the light will continue to illuminate normally even if the system is permanently deactivated
