1. A system for improving the efficiency of a vehicle being driven by a driver, comprising:

  • (a) at least one vehicle data acquisition component disposed at the vehicle, the at least one vehicle data acquisition component being configured to collect time indexed vehicle data, the time indexed vehicle data comprising;

    (i) position data;

    (ii) speed data;

    (iii) torque data; and

    (iv) engine speed data; and

    (b) at least one processor, the at least one processor being configured to implement the functions of;

    (i) determining a slope the vehicle is traveling over at a specific point in time based on the vehicle position data at that point in time;

    (ii) determining a mass of the vehicle at a specific point in time, based on the slope the vehicle is traveling over at that point in time, the speed data at that point in time, the torque data at that point in time, and the engine speed data at that point in time; and

    (iii) producing the performance metric of the driver'"'"'s operation of the vehicle based at least in part on the mass of the vehicle, the mass having been determined using slope data derived from vehicle position data(iv) based on the performance metric, determining if a different fuel map would improve performance, and if so(v) automatically instructing a vehicle controller to change to the more efficient fuel map.
