The Range AFM Plus is a plug-and-play OBD-II device that works with a GM vehicle's Active Fuel Management (AFM) system to optimize fuel economy, allowing the engine to spend more time in fuel-saving reduced-cylinder mode while still delivering full power when needed. It installs under the dash in seconds and uses onboard LEDs to indicate the software version. It does not reprogram the factory ECU. Unlike the AFM/DFM Disabler, the AFM Plus keeps AFM active and tunes it for efficiency rather than disabling it.
