After opening a data file, the Customization Toolbox will appear at the bottom of the screen. The Customization
Toolbox looks similar to the image below. You can use these checkboxes, text boxes and buttons to customize
the look of the downloaded information. The Customization Toolbox is visible at the bottom of the Summary,
Data, Graph, Playback and Notes pages.
1. Checkbox – Used to show and hide the sensor data. If the checkbox is checked, all of the data related
to that sensor will be displayed. If the checkbox is not checked, all of the data related to that sensor will
be hidden.
2. Clear button – A shortcut button that will uncheck all the boxes.

Summary or Notes page.
7. Tire Diameter – Enter the diameter here. This can be the actual diameter of the tire in inches or
millimeters. The unit of measurement can be modified in the Customize File dialog box. If the tire
grows with speed, try to estimate the average or maximum diameter of the tire to get either average
speed or maximum speed throughout the run.
8. Final Gear Ratio – Enter the gear ratio here. The final gear ratio is the number of turns the motor must
make for one full revolution of the wheels. In a direct drive vehicle, this is obtained by dividing the
number of teeth of the spur gear by the number of teeth of the pinion (smaller) gear. If the vehicle used
is a belt drive car or has a front and/or rear differential, you must multiply the spur/pinion ratio by the
ratio of the belt reduction or the differential reduction. Both of these ratios will be numbers larger than
one.
9. Weight – Enter the weight of the vehicle here. Entering this data is optional.
10. Vehicle Name – Enter the name or a short description of the vehicle. Entering this data is optional.
