Performance Data Systems (PDS) delivers a complete Race Intelligence Platform for drag racing, combining professional-grade data acquisition hardware with Caliper PRO software. Designed specifically for racers, our ecosystem captures, analyzes, and transforms performance data into the insights needed to tune faster, race smarter, and compete with confidence.

PDS products are built for drag racers of every level—from sportsman racers to professional teams. Whether you're chasing consistency at your local track or competing for championships, PDS gives you the information you need to improve.

The X1 Data Logger and X2 Data Logger record exactly what your vehicle is doing during every pass. Instead of relying on feel or assumptions, you can analyze engine performance, chassis movement, suspension behavior, weather conditions, and much more to identify opportunities for improvement.

The right channels depend on the car, engine combination, and what you are trying to understand. Common drag racing data channels include:

• Engine RPM
• Driveshaft RPM
• Speed
• Fuel pressure
• Oil pressure
• Boost
• EGT
• Air Temperature
• Coolant Temperature
• Fuel Flow
• Suspension Travel

And other vehicle-specific measurements. The goal isn't simply to collect more data—it is to capture the measurements that help explain changes in performance.

The PDS X1 Data Logger is designed for a wide range of drag racing applications featuring traditional ignition or single-magneto systems and offers professional-level data acquisition with simple setup. The PDS X2 Data Logger is built for the most demanding race programs, offering expanded capabilities for dual-magneto, high-cylinder-pressure engines, and larger sensor packages.

PDS data loggers can integrate with compatible ECU systems to combine ECU information with sensor and vehicle data in the same race data set. Integration capabilities depend on the ECU manufacturer, model, communication method, available CAN data, and the specific PDS hardware being used. PDS supports a range of ECU integration options and can help determine the appropriate hardware and configuration for your application.

PDS data loggers are used across many forms of drag racing, including:

• Top Fuel
• Funny Car
• Alcohol Dragster
• Alcohol Funny Car
• Pro Mod
• Top Sportsman
• Top Dragster
• Nostalgia Funny Car and Dragster
• Bracket and Sportsman classes

As well as other performance racing applications.

Yes. Our products are designed around the same PDS ecosystem, making it easy to expand your race program as your needs grow. Many of the sensors can be reused when upgrading from an X1 Data Logger to an X2 Data Logger system. However, since the X2 features advanced Autosport connectors, some input modules and cables may be incompatible with one another and may need to be replaced.

PDS hardware is engineered for the harsh environments of motorsports, including vibration, heat, and demanding race conditions. All products are IP64 rated, meaning they have very high resistance to both dust and moisture.

The right PDS data acquisition system depends on your vehicle, racing application, and data requirements.

For most drag racing applications, the PDS X1 Data Logger is the best starting point. It provides professional race data acquisition for a broad range of drag racing vehicles and applications, including the sensors and channels racers need to monitor and improve vehicle performance.

For extreme performance and high-demand racing applications, the PDS X2 Data Logger is designed for applications that require higher-capacity, high-performance data acquisition. The X2 is built for demanding race environments and applications with higher electrical and data acquisition requirements.

For complex, specialized, or custom racing applications, PDS Custom System Design provides a complete data acquisition solution engineered around your specific vehicle and requirements. PDS can configure the data logger, XBus modules, sensors, inputs, and system architecture needed for specialized applications that go beyond a standard configuration.

• Choose the PDS X1 for broad drag racing applications and most race programs.
• Choose the PDS X2 for extreme performance and high-demand applications.
• Choose Custom System Design for complex, specialized, or application-specific data acquisition systems.

PDS XBus is the modular sensor and data expansion system for PDS data loggers. XBus modules allow you to add additional sensors and measurement channels to an X1 or X2 Data Logger without replacing the main logger. The system supports a wide range of analog, digital, and CAN-based inputs, allowing you to build a data acquisition system around the specific requirements of your race car.

XBus supports up to 72 channels, giving racers the flexibility to expand their PDS data acquisition system as their race program grows. Explore PDS Modules to see available expansion options.
