In modern motorsports, speed alone doesn’t win races—information does. Whether you’re a weekend warrior at HPDE events or chasing podiums in competitive wheel-to-wheel racing, data acquisition is one of the most powerful tools to improve your on-track performance.
This guide breaks down what data acquisition is, how it works, and why incorporating it into your race program can be the smartest upgrade you make.
🧠 What Is Data Acquisition in Racing?
Data acquisition (often referred to as “data logging”) involves collecting and analyzing telemetry data from your car in real-time or post-session. Using sensors, GPS, and engine data, a properly installed system records your driving behavior and the car’s mechanical state throughout each lap.
Common Data Points Captured:
-
Lap times and sector splits
-
Vehicle speed (GPS-based)
-
RPM, throttle position, and brake pressure
-
Lateral and longitudinal G-forces
-
Steering angle and gear selection
-
Coolant and oil temperatures
-
Tire pressure and temp (with advanced kits)
📊 With this level of insight, you’re not just driving—you’re learning.
🎯 Why Data Acquisition Matters
1. Driver Development
Data lets you identify exactly where you’re losing time. By overlaying laps, you can compare your best sections and spot inconsistencies in braking, throttle application, or line choice.
Example: If your best lap shows late braking in Turn 3 and you’re lifting early on other laps, you’ve just found free time.
2. Car Setup Optimization
Suspension changes, tire pressure tweaks, and aero adjustments are far more effective when you can quantify their impact. Data helps confirm whether a setup change made you faster—or just felt faster.
3. Consistency and Confidence
Knowing how your car behaves at different points in the lap builds confidence. Predictability equals faster, more repeatable laps.
4. Troubleshooting
Sudden drop in lap times? Data can point to overheating, fading brakes, or sensor failure—before it becomes a costly issue.
🛠️ Must-Have Data Tools for Track Drivers
✅ AiM Solo 2 DL
A powerful, compact GPS-based lap timer that integrates with your car’s ECU to log RPM, throttle, speed, and more. Features predictive lap timing and post-session analysis via Race Studio.
✅ AiM MXS Dash Logger
MXS is a dash logger designed to acquire and display data coming from your ECU, the internal accelerometer and gyro, as well as the GPS08 module included in the kit, analog/digital inputs, and predefined math channels. Performance data acquired can also be incremented adding up to 8 expansion modules. Its 5″ display has been has been specifically designed for small cockpit installation.
✅ Sensors & Accessories
-
Brake pressure sensors
-
Steering angle sensors
-
Oil pressure/temp sensors
-
CAN expansion modules for multiple inputs
🧰 These devices create a detailed picture of both the car and the driver, session after session.
🧷 Mounting & Visibility: Don’t Overlook It
Use AAF AiM Mounts for:
-
AiM Solo 2 DL roll bar mounting
-
Flush-mounted dash loggers
-
Secure placement in high-vibration race environments
AAF AiM mounts are purpose-built for BMW platforms like the E36, E46, and E92, ensuring clear visibility and easy access without compromise.
📈 Real-World Gains from Data
Many racers see multiple seconds per lap gained after just a few sessions with proper data analysis. For example, comparing throttle traces lap over lap often reveals early lifts or hesitation in acceleration zones that can be corrected for free speed.
Data also enables faster adaptation at new tracks, reducing the learning curve from days to sessions.
✅ Final Thoughts
Data acquisition isn’t just for pros—it’s for any driver who wants to be faster, more consistent, and more informed. Whether you’re using a simple GPS lap timer or a full telemetry suite, investing in data is investing in your success on track.
Let Advanced Auto Fabrication help you set up your data acquisition system right, with AiM hardware and custom-fit mounts that make integration clean, functional, and race-ready.
