PerformanceBox as a Performance Meter
Not only is the new PerformanceBox the most sophisticated Performance meter on the market, but it is also one of the simplest to use, with many features normally found only on professional test equipment. You can quickly measure the acceleration, braking and cornering performance of your car without having to set anything up beforehand, and there is no need to perform any calibration. Because PerformanceBox is based on GPS, you get so much more for your money than just a simple performance meter.
PerformanceBox uses a GPS system with an update rate of 10 samples per second, which is the fastest GPS engine in its class. From this you get a very accurate speed (±0.1kmh), cornering g-force, acceleration g-force and a very accurate distance measurement (±10cm in 400m).
PerformanceBox is based on VBOX technology, which has been used all round the world by the majority of motor manufacturers for a number of years to measure speed, distance and aceleration.
Using PerformanceBox as a performance meter could not be simpler, you connect it to your cigar lighter socket, wait a few seconds to get GPS lock, put it into 'Performance Mode' and drive!
To swap between the 6 different performance meter screens, simply press the up and down arrows.
Performance ranges and units are fully user adjustable, which means if you want to measure a specific acceleration or deceleration range, for example 35-65, then this is very easy to do.

Quarter mile testing
Using PerformanceBox to measure your 1/4 mile is very easy, simply scroll the screen to the 1/4 mile screen, and then go! The elapsed time and trap speed are then both displayed in real time on the PerformanceBox screen. You can choose to make this measurement either with or without the NHRA 1 foot rollout method.
The 1/4 mile times measured by PerformanceBox are accurate to within 0.1s. After an acceleration run, you can download your data from the SD card and overlay a previous run to see where you lost or gained time.
Who uses PerformanceBox?
PerformanceBoxes are now being used by to measure acceleration, braking, and lap times by many car and bike magazines, such as EVO, AutoExpress, Autocar, Redline, Max Power, Banzai, Japanese Performance, Performance BMW, Car & Driver, Performance Bikes, Ride, to name only a few.
Using the supplied software and an SD flash card, you can download the speed/time/distance/acceleration data from PerformanceBox via USB and analyse it using the PerformanceTools analysis software:
Another very powerful feature is the ability to export your PerformanceBox position files to Google Earth, allowing you to plot your vehicle's path onto a satellite image of the area.
