PerformanceBox as a
Lap Timer and Predictive Lap Timer |
    |
|
Lap Timing Because PerformanceBox uses a fast GPS engine, it knows precisely where you are every 1/10th of a second. Using this information, it can compare your current position with a number of stored reference points and use this information to trigger a lap timer function and predictive lap timer for instant driver feedback. Setting it up is very easy and only has to be done once. Just put PerformanceBox into setup mode, and drive over the point you wish to define as the start/finish line. This point is then converted into a line at 90 degrees to your direction of travel, and stored in the internal memory. |

Up to 6 Splits can be defined in a similar manner, and you can freeze corner exit speeds by using the Speed @Split function, making it more than just a simple lap timer. There is a 99 lap memory, with every lap and split recorded to the SD card for later analysis.

Predictive lap timing is a great way of giving instant feedback, which helps you quickly find valuable improvements in your driving. Predictive lap timing works by comparing your current lap with your previous best, and showing the difference in real-time. When you take a corner better than before, you can instantly see how much you have gained, rather than waiting for the end of the lap, which is often too late. |

You can also try out many different techniques around one-lap to find out which ones work immediately, saving valuable track time. The 'LineSnap' algorithm is a real breakthrough in technology, as it uses GPS position to accurately line up the laps. The traditional way has been to use elapsed distance, either from a wheel-speed sensor or calculated from GPS velocity. This ensures that the predictive lap-timing is accurate to 0.1s, even around long circuits such as the Nürburgring. |

Whether you're a pro or an amateur, you will love predictive lap-timing. You quickly learn where to gain time, and you can make big gains in consistency. For instant feedback on driving technique and line, Predictive Lap-timing in PerformanceBox cannot be beaten. Other Lap Timing Features There are a host of other features such as modes for slalom courses, a one-shot mode for Sprint circuits, different options for split times, and you can load and save all start / finish and split points to a file on the SD card. No other lap timer combines all of these features in one easy to use and affordable unit. |
