A fuel economy method and system consists of using a signal control unit connected to a throttle of a vehicle and to a mass sensor for sensing a mass of a load carried by the vehicle. When the sensor senses that the mass is within a predetermined mass range, the signal control unit reduces the range of output of the engine. The unmodified engine output range and modified engine output range extend from a minimum engine output to, respectively, an unmodified maximum engine output to a modified maximum engine output lower than the unmodified engine output and thereby requiring less fuel. Accordingly, the range of engine output, and notably the maximum engine output available, is reduced when the mass is in the pre-determined mass range, thus reducing fuel consumption compared to the unmodified output range.
