Accuracy and reliability are paramount, because the entire ecosystem of the race hinges on the validity of this data.
The system relies on a combination of hardware and software. Tiny transponders are installed in each car, emitting a unique signal that identifies the vehicle as it passes specific points around the track. Buried beneath the track surface are timing loops, strategically placed at the start/finish line, sector markers, and other key locations. These loops detect the transponder signals as cars pass over them, sending that information to a central data acquisition system.
The data acquisition system is the brains of the operation, a complex array of servers, software, and network infrastructure. It receives the raw signals from the timing loops, processes the data, and then distributes it to various displays and systems. Race control receives the information to monitor safety and enforce the rules. Teams receive the information for strategy, drivers receive the information for adjusting their driving and the public receives the information through broadcast and websites to monitor the race progress. Without these foundations, racing at IMSA would not exist.

Lap times represent the time it takes a car to complete an entire circuit of the track, while sector times break down each lap into smaller segments. These metrics are not just indicators of speed, they are the foundation for assessing driver and car performance. Teams analyze lap times to identify areas where a driver is consistently losing time or where the car’s setup could be improved. Sector times provide an even finer level of detail, pinpointing specific corners or sections of the track where performance gains could be made. Race strategists utilize these data to anticipate the optimal moment for pit stops, aiming to capitalize on periods where the car is performing at its peak.
Position and Gaps
The system provides a live, continuously updated view of the running order, showing the position of each car and the time gap separating it from the cars ahead and behind. This is essential for understanding the dynamics of the race, showing which drivers are gaining ground and which are struggling. This information also influences strategy and decisions on the track, because drivers can decide whether to push harder to pass a competitor, or hold their position and conserve fuel.
Pit Stop Timing
In endurance racing, pit stops are vital. IMSA Timing and Scoring provides a precise measurement of pit stop duration. From the moment the car enters the pit box to the moment it leaves, every second is recorded and analyzed. This data is used to evaluate the efficiency of the pit crew, identify areas for improvement in pit stop procedures, and strategically optimize pit stop timing during the race. A faster pit stop can gain positions on track, and the data provided by the timing system is crucial in achieving that.
Penalties
IMSA has strict regulations regarding driver conduct, pit lane speed limits, and other aspects of racing. IMSA Timing and Scoring is instrumental in detecting and enforcing penalties. For instance, if a car exceeds the speed limit in the pit lane, the system automatically flags the infraction, allowing race control to impose the appropriate penalty. These may include drive through penalties, stop and go penalties, or even disqualifications. The accuracy of the timing system is paramount in ensuring fair enforcement of the rules.
Speed Traps
Strategically placed around the track, speed traps measure the top speed of each car at specific points. This data is used both for safety and performance evaluation. It can help identify potential mechanical issues affecting a car’s speed, and is also used to monitor compliance with regulations regarding engine power or aerodynamic configurations. Speed trap data adds another layer of insight to the data that racing teams and fans consume.
