Enhanced Fuel Economy
Active Fuel Management, available on most GM trucks and SUVs, helps lower fuel costs by enabling V8 engines to behave like four-cylinder engines when cruising with light loads, while seamlessly unleashing their full muscle whenever needed. The AFM+ device allows the vehicle to run in 4 cylinder mode more often, for improvements in efficiency.
Features:
- Simply plug in Range into your onboard OBD-II port and it instantly begins working with your Active Fuel Management to optimize your fuel economy.
- Range AFM Plus optimizes your performance by better identifying your driving situations helping you get more miles out of a gallon of gas.
- The average driver will save $250 a year.
- *It is suggested the device be unplugged if the vehicle is not being driven daily or left for a few days. There may be a power draw on the battery in some applications.
