For all vehicles included in this LED profile, extensive telemetry data was collected through meticulous test sessions, allowing for the precise determination of optimal shift points for each gear. This profile also considers driver reaction time - enabling drivers to focus solely on the bright shift flash in the Ascher Racing LED profile, rather than monitoring the Rev LEDs, for near-perfect shift timing accuracy within a few hundredths of a second. This results in a measurable stopwatch advantage, yielding time savings of a few hundredths up to two tenths of a second each lap, depending on the vehicle’s engine characteristics and the grade of inaccuracy of in-game LEDs.
