 2 MILLISECOND STEPS USED IN PROGRAM

 WITH INPUT "ENTER DRIVE TRAIN INERTIA TYPE (MASS/RPMS)",
   RPMS: DECREASES ENGINE TORQUE, IN PROPORTION TO INERTIA
   MASS: INCREASES TEST WEIGHT, IN PROPORTION TO INERTIA,
         MASS IS MASS FACTOR OR EFFECTIVE MASS OF INERTIA
         MASS HAS NO PROBLEMS WITH EXTRA LOW TRANSMISSION
         GEAR RATIOS, CRAWL RATIOS > 100:1

 A star in "high gear road speed vs engine speed chart" at the end
   of a mph line, means that the piston fpm is greater than 2600 fpm.

 Use the .dat file to manually set the efficiency of gearbox gears,
   primary and final gear reduction. Or let the program calculate the
   efficiency.

 If the transmission has a 'low range' and a 'high range' set of gears
   (18 speed tractor-trailer), then use the .dat file to manually set
   efficiency. A 3:1 to 4:1 gear is added is series with the
   transmission to get the low range. Add the efficiency of the added
   gear to the 'high range' gear efficiencies to get the 'low range' gear
   efficiencies.

 Use "chassis drivetrain friction eff." in the .dat file to add more
   overall loss to the calculated gear eff. (4 wheel drive SUV)

 ET is elapsed time, it starts when tire clears drag stage light sensor.
 ED is elapsed distance, it is measured from drag stage light sensor.

 Transmission Gear Ratios section of .dat file:
   If overall transmission gear ratios "A" are used, then gear efficiency
   should be ~10% (efficiency from engine crank to wheel rims of a manual
   transmisson).
