If you want to know exactly how well your driving skills are doing and if your performance modifications are making a difference, then you will want to check out the PerformanceBox or DriftBox GPS data acquistion units. Both units feature a Performance Meter, Lap Timer, Data Logger, and Power Calculator.
The Performance Meter allows you to calculate top speed, average speed, 1/4 mile time, GForces, 0-60 times, and more. All this data is saved on a SD memory card which can then be put on your computer to showcase the graphs and data to analyze your driving. The Lap Timer takes a fixed position in which it will give you your best lap time, current lap time, and even your speed. You can define up to 6 splits and even track your corner exit speed. The Data Logger function is a full data logging software. This software allows graphical analysis of acceleration, braking, cornering and lap times. You can overlay up to four files, and you get an accurate track map to compare your driving line between different laps. Finally the Power Calculator is like having a real dyno in your own car. Meaures results in BHP or KW, analyzes your acceleration to give you power output at the wheels, you can carry these runs out in 2nd gear for safe and low speed driving, power can also be calculated at the flywheel. There are two parts to the testing process: the acceleration run, which gives you the power at the wheels minus the losses caused by tyre and air resistance. The second part of the test measures these losses and also estimates gearbox losses. The Power Mode is also an additional tool for car tuning, where access to a chassis dynamometer is not possible.
The DriftBox features all the above functions but includes the Drift Analyzer system. Driftbox was initially developed for use in the Japanese D1 Grand Prix series to assist the judges award points during the competition, and has become in effect the fourth “Judge”. Every vehicle which competes has a DriftBox Pro fitted during each run, and the judges get a points score for each corner based on Entry speed, Drift Angle and Cornering Force. Cornering force is used to judge how well the car is setup, the higher the cornering force, the more power and skill are needing to slide the vehicle.
Until now, the drift angle had to be estimated, but with DriftBox the guesswork has been removed, allowing much fairer comparisons to be made between competing drivers. Not only does DriftBox give feedback on angle, but also entry speed and cornering G-force. This information is displayed to the driver, and can also be transmitted to the judges and spectators in real time using the optional Racelogic telemetry system.
