Fuel-to-end and required-stops are recalculated every lap from your actual burn rate — not a static average — so you know the real margin, not a guess.

A pit window, not a single guess.
Race Engineer tracks tire wear, fuel, and pace together to flag when the window opens and when it starts costing you time to wait.
