GPRO Calculator
Race engineer for Grand Prix Racing Online managers
GPRO Calculator is a companion tool for managers of Grand Prix Racing Online (GPRO), the online motorsport management game. It reads your own team data through the game's read-only API and turns it into the three numbers you need before every race: the car setup for each session, how much fuel to load at the start and at every pit stop, and which tyre to fit and when to stop. Available in six languages. Independent project, not affiliated with GPRO.
Features
Car setup for Q1, Q2 and the race, from your own car, driver and the weather forecast
Fuel plan: litres at the start and in every refuelling box, including a reserve box for when the weather changes mid-race
Tyre strategy: which compound, how many stops and on which laps, with the cost of each alternative in seconds
Post-race report: predicted versus real, so you can see what worked and what did not
Driver market search across the full public driver list
Six languages, free race credits on sign-up, no card required
Use Cases
Preparing a race weekend in five minutes instead of a spreadsheet
Deciding between one stop and two when rain is expected mid-race
Checking after the race whether the plan or the driving cost you the position
Finding a driver who is better than yours without paying more
Comments
I play Grand Prix Racing Online myself, and I built this because before every race I was doing the same maths by hand: how much fuel to load, which tyre lasts the stint, when to pit. The tool reads your own car, driver and weather and gives you the numbers to type into the game. It also learns from real finished races, so the fuel and tyre figures get closer to what actually happens on each track. Free for your first 5 races, no card needed. It is fan-made and not affiliated with GPRO. If something is wrong or unclear, tell me: I fix it fast.
