Overview

Range Technology DFM Modules

Range Technology DFM modules are 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 DFM 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. 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.
