Abstract of the Disclosure: An analog signal representation of the ground speed of a prime mover driven vehicle is modified by the vehicle drive train ratio factor to produce an analog signal representation of the theoretical speed of rota- tion of the prime mover rotating element based upon vehicle ground speed and another analog signal represen- tation of the actual speed of rotation of the prime mover rotating element based upon selected prime mover operating parameters is produced. A variable gain amplifier circuit converts the theoretical speed of rotation analog signal representation into a system output calibrated analog signal representation of the actual speed of rotation of the prime mover rotating element based upon vehicle ground speed by incrementally adjusting the potential level of the theoretical speed of rotation analog signal represen- tation in a direction toward that of the prime mover operating parameter based actual speed of rotation signal representation.
