Understanding Telemetry in iRacing

Learning how to read and understand telemetry in iRacing is the key to unlocking consistent performance gains. Telemetry records every driver input and car response, including throttle position, brake pressure, steering angle, suspension movement, and tire temperatures. Throttle traces quantify how smoothly power is applied on corner exit, brake traces reveal whether deceleration is efficient or inconsistent, and speed traces expose where momentum is being lost compared to a reference lap. By combining these data points, drivers can move beyond guesswork and make precise, evidence-based adjustments that directly improve lap times.
