Data Acqusition

Data Acquisition is essential to performance improvement. It is impossible to accurately measure the maximum levels of grip, acceleration, and braking, without data.


•         Data Acquisition Systems, or Data Loggers, gather information that allows you to analyze the performance of you and your car.

•         These are not lap timers. These systems, usually GPS-based, gather information from on-board sensors located in one small box.

•         The information can be simple: basic data is usually time, speed, distance, position/location, and load (G) sensors in lateral and longitudinal directions.

•         With these basic signals, a map of the track can be created, showing exact location, G-loads, and segment/lap times.

•         Data is stored on a memory card, and can be downloaded to computer for a detailed, second-by-second, corner-by-corner, lap-by-lap dissection of performance.

•         This data can be used after each session, evaluating driver, engine, and suspension performance to determine where to make immediate improvements.

•         The data can also be reviewed later in more detail, to search for long-term improvements.

•         Many of the same features are available on other systems, but some are exclusive to the Race-Technology DL1 (which is why that is what we use!)


Basic signals for evaluating driver performance:




Vehicle position

Lateral G’s (side load)

Longitudinal G’s (accel/decel)


Using a combination of these signals, we can draw conclusions about what the car and driver are doing, and what can be improved.
