Enter your tank capacity and a target pace once, per car. GBC reuses it for every track and every strategy you build on that car — no re-entering the basics every time you show up somewhere new.

Track distance, tank size, and burn rate combine into the numbers that matter: total fuel needed, laps per tank, how many stops the race actually requires, and the exact lap to box.

The pit wall shows fuel remaining updating lap by lap while the session is live, calculated straight from GPS speed. The crew always knows where the car stands — no stopwatch, no spreadsheet.

Log a splash-and-go right from the pit wall and the remaining-fuel math adjusts instantly. Log what you actually burned after the session and GBC calibrates your car's real rate — every plan gets sharper than the last.

With CANBUS connected, the pit wall reads the same fuel level the ECU itself reports — a real sensor reading, not a GPS-speed estimate.

Burn rate stops being a GPS-speed proxy and starts factoring what the engine is actually doing — RPM and load, straight off the crank sensor.

The measured ECU fuel level runs alongside the GPS-based estimate on the pit wall in real time — if the two start to drift apart, the crew sees it immediately.

Refuel & Learn (IV) already calibrates from what you log after a session — with CANBUS, it calibrates against real measured burn every lap instead of one number at the end.
