For motorsports enthusiasts, especially those involved in track days and autocross, capturing and analyzing performance data is crucial for improvement. While phone-based applications like Track Addict offer a starting point, their reliance on smartphone GPS often falls short when precise data is needed. This article delves into enhancing your racing in-car camera setup by integrating an external GPS and leveraging the OBD2 port for richer, more accurate performance analysis.
The GPS Accuracy Challenge with Phone-Based Racing Apps
Smartphone GPS, while convenient, is not always optimized for the demands of high-speed racing. In autocross and track environments, the nuances of cornering, braking points, and precise lap times require a higher degree of accuracy than standard phone GPS can typically provide. This limitation can lead to inconsistent and less reliable data when using apps like Track Addict for performance tracking.
Upgrading to Race Chrono Pro and OBD2 Connectivity
To overcome GPS limitations and gather comprehensive data, consider upgrading to a dedicated system. Race Chrono Pro, paired with an external GPS receiver like the Race Box Mini GPS, offers a significant leap in data accuracy. Furthermore, integrating an OBD2 adapter, such as the OBDLink LX, unlocks a wealth of engine and vehicle performance data directly from your car’s computer.
This setup allows for simultaneous Bluetooth connection of both the Race Box Mini GPS and the OBDLink LX to your smartphone, which serves as the display and recording device, typically mounted on the windshield. Using your phone’s camera alongside this setup provides synchronized video footage with real-time data overlays.
Race Chrono Pro vs. Track Addict: Enhanced Data and User Experience
While both Track Addict and Race Chrono Pro are valuable tools, Race Chrono Pro offers a more intuitive user experience for real-time data visualization during racing. Although both programs provide similar data logging capabilities, Race Chrono Pro excels in presenting in-car, real-time data in a more easily readable format, which is beneficial even for autocross events where quick data interpretation is key.
A significant advantage of Race Chrono Pro is its streamlined video and data overlay creation. It allows for direct in-app video overlay generation and export to platforms like YouTube or Google Drive. This eliminates the need for separate video editing software like Race Render, which is often required with Track Addict, simplifying the workflow for sharing and reviewing your racing sessions.
However, it’s worth noting that Race Chrono Pro’s pre-designed data overlays offer less customization compared to the Track Addict/Race Render combination, which allows for tailored layouts and information displays.
Cost-Effective Racing Data Acquisition
The Race Chrono Pro, Race Box Mini GPS, and OBDLink LX setup represents a relatively affordable entry point into enhanced racing data acquisition, costing approximately $200 in total. While more advanced and integrated systems like Catalyst or AIM offer superior features, they come with a significantly higher price tag. For enthusiasts looking for a balance of performance and cost, this OBD2 and external GPS based setup provides excellent value.
Considerations for Setup and Data Reliability
While this system offers numerous advantages, it’s important to acknowledge that ensuring all components are properly connected and activated before each session requires attention. Forgetting to link or power on a device can lead to data loss, which is a common pitfall. Developing a pre-session checklist can help mitigate this risk and ensure consistent data recording.
Conclusion: Elevating Your Racing Performance with Data
Integrating an OBD2 port connection and external GPS into your in-car camera setup is a game-changer for racers seeking accurate and insightful performance data. The combination of Race Chrono Pro, Race Box Mini GPS, and OBDLink LX provides a user-friendly, cost-effective solution to elevate your racing analysis and drive continuous improvement on the track. By leveraging the power of OBD2 data and precise GPS, you can gain a deeper understanding of your driving and unlock your full potential behind the wheel.
