Engineers use telemetry in real-world racing to figure out ways to improve performance. This performance could include improvements in overall lap time, better tire wear, lowering fuel usage etc.
Several sim racing titles support the use of telemetry, but we'll cover only iRacing and Assetto Corsa Competizione (ACC) in this article.
What is telemetry?
Telemetry refers to the collection of measurements and the automatic transmission of this data for monitoring and analysis.
