After break in make sure your motor is completely cool before Dyno testing. Run the motor up just once to burn any foreign material from between the brushes and the commutator. In most cases the second test may be saved to your data file. You may enter a New Track Name now. Type in a name you will recognize when looking for it in your list of motor test files. If you race more than one class at any particular track you may type the track name and "stock" or "modified" to keep the two seperate but available. Detailed information can be kept in the lowest box in the Window about the car, motor, battery pack or anything....

Put the motor in the car with someone keeping time and counting your laps for you. You will have to use your expertise to estimate the gear ratio to run the very first time on a new track. When you are finished on the track, retrieve the same motor file. Then go to the Oval Gearing Screen.

Click the Set button to Associate the motor on the Right side of the window to the Track Name on the Left. Click the OK button when the 'Out Of Range' warning is displayed.

After you have entered the actual results from the test on the track with the test motor click the Apply button at the bottom of the Window.

At this point the Oval Gearing Window is ready to calculate the gearing and rollout for any of your motors using your actual ’On Track’ Statistics. By telling the program what your car can do under certain motor conditions recorded from the motor and on track test, it will accurately be able to calculate the best rollout, thus gear ratio for the motor in question.
