It is important to use the most recent good full run as the reference. Change the run used as the reference (old) run as the race day progresses. Runs that had tire spin, unusual 60 ft times, or gusty wind conditions should not be used for the reference run. The reference run should be the most recent good full run when the vehicle performed as expected. The reference run, on which the prediction is based, is selected by the user.

The Dial-In is predicted from 1 previous reference run (no database of runs is used or required). The program will automatically go to the fuel setup program during the first use. However, a setup fuel choice must be made to get accurate ET predictions. The program works for all length tracks and is compatible for use with either gasoline or methanol fuel.

The SAE method should produce more consistent results for large barometric pressure changes or different track elevations. The correction factor method used can be changed from STD to SAE in the program setup area. The Standard Dial-In method is Computech’s easiest to use and more accurate ET prediction program. This program is designed to help class and bracket racers predict an elapsed time (ET) for the next run based on changes in the horsepower correction factor. Below is just a summary, but to really appreciate all that the “Race Air Pro” can do, you will need to read about the features below, or you can go directly to the Computech Racing Systems Web Site, and view the entire instruction manual.
