Taking the cue from the Chevrolet Corvette’s racetrack data logger which is a built-in option, Porsche too has adapted a similar setup but with a small twist. The new app from Porsche enables your Android or Apple smartphones in a lap timer, dash camera, and a telemetry recorder so that you can evaluate your track day adventures.
Porsche Track Precision app, updated newly, couples with the Sport Chrono optional package installed in the Cayman GT4, GT3 RS and 911 GT3 to offer data-heavy study into your racing lines, lap times, and telemetry aided video playback, steering, throttle and brake feed, and hordes of other details. The entire info is packed into the tiny screen of your Smartphone.
The app carries info of 60 racing circuits and comes preloaded with them. If a particular is not loaded into the system, then the first round of lap would teach the GPS system of the phone on the track. Then all you need to do is to mount the phone on the dash or the windshield with the camera lens pointing outwards, and the clock to register your lap timing is on.
If you want more enhanced data exchange, the Porsche with Sports Chrono come prewired so that an optional lap trigger can optionally installed. This is a light sensor mounted on the rear-side window, and it is tripped by a mechanism with is located at the start/finish circuit lines. Once the lap is recorded by the app you can enact video playbacks of it with the lap times being shown as overlay and it further shows inputs of steering, throttle and brakes, gear selection, speed, g-force rpm and your position behind and front of your ghost car from previous lap. The app is available for both the Android and Apple versions, and that is what you need to get and, of course, you will need a 911GT3 or Cayman GT4.
