Power Calculations
PerformanceBox can help you to meas
ure the power developed by your car’s engine, either at the
wheels or flywheel. Having set the vehicle weight, results are calculated from the measurements
taken by the fast GPS engine to give you useful guidelines to the car’s brake horsepower or
kilowatt output. Because these calculations are made from the GPS data rather than
accelerometers, your results are likely to be more consistent and accurate.
Data Logger
For drivers keen to improve their lap times and get valuable feedback on technique,
PerformanceBox includes a sophisticated, fully functioning data logging package. If used with a
64mb SD card, PerformanceBox can log up to 50 hours of continuous data, which can be analysed
in great detail in the available software.
This software allows graphical analysis of acceleration, braking, cornering and lap times, and if the
PerformanceBox is used in conjunction with a Micro Input Module, data from the vehicle itself
(such as RPM and throttle angle) is recorded alongside the GPS parameters.
You can overlay up to four files, and you get an accurate track map to compare your driving line
between different laps. The software also features a graph measure tool, allowing for precise
analysis of performance figures. Data-logging capabilities are further enhanced by automatically
generated text data on the SD card.
