Active Fuel Management (AFM), also known as cylinder deactivation, is a technology used to improve fuel economy by shutting off a portion of the engine's cylinders under certain conditions. While it is commonly found on larger engines like V8s, it is not exclusive to them and can be used on smaller engines as well. Therefore, Technician B is correct in stating that it increases fuel economy.
