ECM mileage is based on the number of transmission output shaft rotations, and is calculated along with the programmed rear end gear ratio, transmission gear ratios, and revolutions per mile for the programmed tire size. Actual mileage will vary according to tire wear... as your tires wear down, the actual mileage you travel will decrease.
