The ET Predictor Pro is our entry level ET Prediction software. It is the same ET Predictor that is built in to our RaceLog Pro software. While you can store an unlimited number of runs, it does not have a database like our RaceLog Pro software. Your runs are stored as files. Weather data must be entered manually from your weather station or gauges.

New (- Zoom +) feature! Computer display screens keep getting bigger so we've added the "- Zoom + " feature so that you can adjust the size of the program window to your screen resolution (dpi) or personal taste. Put away your reading glasses! All windows are also movable and individually resizable. Window size and location is remembered and restored the next time you start the program.

ET Predictor Pro is an ET Prediction system for your personal computer. It supports an unlimited number of run files. It tracks weather conditions and run information. Weather correction calculations support gasoline, methanol, and E85 fuel.

ET Predictor Pro will install on all Windows 32/64 bit platforms and includes TrueWind ET Prediction, an innovation from Family Software, and has a separate ET Predictor Mode for eighth mile racers.

ET Predictor Pro uses our proprietary Horsepower Correction formulas for ET Prediction, the only completely scientific formulas in the industry. Our ET Prediction is based on the amount of RELATIVE OXYGEN in the air and a COMPUTER MODEL of your particular cars performance. We DO NOT average weather data, run data, or use outdated (and inaccurate) Density Altitude calculations for ET Prediction. Our original formulas are perfectly accurate and have never needed changing.

Our ET Prediction software has always used Vapor Pressure (Water Grains) and is the only ET Prediction software to handle humidity calculations correctly. You won't find any "fudge factors" in our software. Here are some of the calculations provided:

Horsepower Correction Factor
Air Density Index
Density Altitude
Vapor Pressure
Water Grains per Pound
Dew Point Temperature
Horsepower Corrected Weight

Standard Pressure ET Correction
Predicted 60' ET
Predicted 330' ET
Predicted 660' ET
Predicted 1000' ET
Predicted 1320' ET
Throttle Stop Prediction
Run Completion ET
TrueWind 660' Prediction
TrueWind 1000' Prediction
TrueWind 1320' Prediction

We are the original ET Prediction software developer and the innovator in this industry!

Remember, often imitated, but never duplicated, we have been "The ET Prediction Experts" since 1986.
