1. A method of using vehicle position data in a vehicle having an engine control unit (ECU), comprising the step of:

  • (a) while the driver is operating the vehicle, automatically collecting vehicle data, the vehicle data including vehicle position data in the x, y and z axes; and

    (b) using a first computing device to iteratively evaluate a first parameter of interest from changes in the z axis position data over time, thereby producing a first sequence of values; and

    (c) using said first sequence of values to compute a second parameter of interest that is provided to the ECU and is used by the ECU to control vehicle operations.
