A microprocessor controlled shift indicator reduces fuel consumption for passenger cars with manual transmission, especially in city traffic. The system automatically senses and stores the number and values of the total gear ratios between the engine and the rear axle. The expected engine speed on the next higher gear is continously calculated and used as the criteria for shift indication. One type of system can be used in almost all car models independant of transmission ratios, number of gears or final drive ratio.
