Features Track mapping with lap and segment times Acceleration and lateral g-forces Data from optional inputs Engine RPM Battery voltage Vehicle speed Stop guessing and start winning! The new G2X GPS Data Acquisition System from Racepak and MSD Ignition can help you improve your lap times by showing you how you and your car react in race situations. The G2X provides accurate speed, lap and segment times through the use of Global Positioning System satellites. This means there's no need to set up track-side beacon transmitters, receivers, or their associated wiring. The technology employed in the G2X has been utilized for years in various forms of Motorsports. We have logged thousands of on-track laps in creating an economical data logger that is both rugged and dependable in a wide variety of environments. Information about braking, steering and throttle can be easily added through Racepak's V-Net Technology. After running a few laps, simply remove the Compact Flash card from the G2X and download the information to your PC. Racepak's Datalink software is easy to view and navigate. Once a track map is created, you'll always have it on file to use at other events.
