DFM MODULE GM REFRESH RANGE TECHNOLOGY
DFM Module for Refresh V8 models - 2023-2024 ZR2 & LTZ SILVERADO 1500
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
- 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
