Many autocross drivers employ a $200 Android mobile device app called SoloStorm. There are a number of external GPS receivers on the market, but some of the more highly regarded ones are the Garmin Glo (which retails for about $100), the Dual Electronics XGPS150 and 160 (also about $100 retail), and the Racelogic VBox Sport (MSRP is $429). However, it’s possible to amp up most systems’ flexibility and accuracy through a separate GPS unit with Bluetooth connectivity. In most cases, the phone must be mounted vertically to the car’s dashboard. It’s important to properly mount the device in order to use the video function and acquire the GPS signals. Have you seen those in-car YouTube videos with the dashboard-style overlay showing data like synchronized track position and speed? They were likely made using smartphone apps. There’s actually a free version available on the Mac App Store and Google Play, but it’s fairly limited. A similar app, available from RaceRender for both Apple iOS and Android devices, is TrackAddict by HP Tuners.
Automatic start/finish camera control also eliminates nonessential grid and cooldown footage. Advanced versions can employ the phone’s native video capability-or interface with POV cameras like the GoPro Hero3 and 4 as well as Sony offerings. The app records data from the session, which you can analyze later. You can load track info prior to a session, and timing starts automatically when you cross the start/finish line. Said to be the most popular timing app in the world, Harry’s LapTimer boasts GPS coordinate info from nearly 800 tracks around the globe and has specific configurations for many facilities that offer varying track options and both clockwise and counterclockwise orientations.

You can drill deeper and see what’s best suited for your vehicle, venue and budget. It’s by no means complete, but it will set the stage. What follows is an introduction to a wide range of products. Some of this equipment costs less than you’d expect, too. Today’s arsenal of state-of-the-art equipment includes transponders with data-sharing capabilities, onboard vehicle data acquisition, miniature POV cameras, and smartphone apps that tie it all together. So much valuable on-track information is there for the taking, and recent advances in data acquisition have made it easier than ever for drivers to collect it, evaluate it, and use it to run quicker lap times. It’s time to put your clipboard and stopwatch in mothballs.
