вот описание:
GPS Performance is a must have application for people with performance cars interested in performance statistics. Using a regular GPS receiver and sophisticated alorythms, GPS Performance is able to accurately measure 1/4 mile dashes and 0..60 timings. Circuits can be defined for timing laps and up to 5 split times per track can be added. Of course the runs are fully configurable, allowing custom distances and speed ranges to be specified, and tracks are created simply by driving around the circuit. Each type of run has its own memory, storing the last ten runs. The best time and average time are displayed and individual runs can be deleted from memory. Different runs can be plotted and overlayed against each other using an informative graph. G forces for recorded runs can also be plotted and compared. Use GPS Performance to discover exacly what your car is capable of and boast to your friends. Use it to perform ''before and after'' runs to test performance modifications such as sports air filters and sports exhausts. It can also be used to detect small changes in performance to give early indications of possible engine problems.
