Real-Time Fuel / Refuel Strategy. No Mental Maths.
This system pre-calculates an entire fuel-tank's worth of full-lap segments (recommended Refuel values), which you can then choose from (no more under/over fuelling).
Top: Overall Requirement Middle: Clickable Full-Lap Segments (up to full-tank) Bottom: Current Onboard Fuel Status
Long or short stint you can be safe in the knowledge that the Refuel value you pick will get you back to the pits at full race speed and with as little excess fuel onboard as possible (1L ≈ 1KG). If weight doesn't matter, why do we handicap faster cars using BOP?
Running alongside our Real-Time Telemetry Companion App on your PC (not Consoles), the fuel consumption and race duration etc. are kept entirely in sync ensuring accurate calculations, significantly reducing the need for additional (manual) user interaction (brain power).
Helps you to make rapid decisions based on the ever changing nature of racing, ensuring that you always "FinishRaces" while performing at your highest ability.
Compatible with any sim on PC and Console.
What is FinishRaces?
FinishRaces reads live telemetry from your sim — or takes your own manual inputs — and turns it into a real-time refuel recommendation that updates continuously as the race unfolds, on any race length from a 30 minute sprint to a 24 hour endurance event. It runs as two connected screens: plan your Weekend, then run the Race. An optional, lightweight Windows Companion App handles the telemetry side quietly in the background; without it, everything still works, just with a little more manual input from you. Here’s exactly how it fits together:
How it works
Sim PC
FinishRaces
Mobile Device(s)
Install the Companion App — (Optional but highly recommended if you're on PC) a small Windows tray application (~7MB) that reads the telemetry your sim already produces and sends it to FinishRaces every few seconds. It fires quietly in the background while you race.
Your Telemetry Key can be found under your Account tab
Set up your Weekend — your Track / Car (combo) management suite (saves automatically for future use), so you don't have to keep re-entering your base lap time (PB) and fuel burn per lap (FL) again and again for each Track / Car combo!
Enter your PB, FL and Free Practice, Qualifying and Race Session durations / number of laps (takes under a minute).
This will give you a high level (saved) view of all sessions in your Weekend and is the jumping off point to load up your sim and begin each Session in-game and on here simultaneously.
You can save up to 10 Track / Car combos (Weekends) before registering.
Load up your Session — This is where the magic happens! Click the alongside each Live Session on the Weekend screen to load up that Session's settings. Sessions can be controlled by a Countdown Timer or Number of Laps.
This screen is designed for in-game use, so a higher contrast layout, the use of large buttons, large icons, large fonts, single click data manipulation etc. has been implemented and it can also be made fullscreen for the best use of smaller screens (device dependant, doesn't work universally unfortunately).
Your main focus needs to be on the race, NOT this screen, we understand that you have more pressing concerns while racing!
Your fuel requirement and lap data updates automatically as the race unfolds (with the occasional re-syncing from the Companion App when Connected or manual tweaking when not). Tap the full-lap segments to Stage (in the "Pit" section) how much Fuel to add at your next stop — you will STILL need to set that figure in your game's pit setup (we're not that clever... yet).
Console Users
For Console users, all you have to do is hit the Engine Start button during the Formation Lap and then the Race Start button when the green light Go-Go-Goes and the timer will automatically start counting down in time with your game.
Engine Start / Go! Go! Go!
End Race
The Onboard Fuel value simulates burn down based upon your PB and FL. So you will have to manually resync the Onboard Fuel value (PB and FL will change less frequently) but in reality, these tweaks tend to be very minor and can easily be done on Pit Straight.
PC Users
Once your Session config is setup correctly and you are running the App on your PC, "Unpause" the App icon to begin the periodic polling of the FinishRaces server for your most recent Live Telemetry. If it remains persistently "No App / Not Connected", then you will need to ensure that the "Telemetry Key" in your App matches the one on your Account.

Data Burst
It is advisable to use the Race (Session) Screen to calculate your Grid Fuel load (first stint) while the App's (Data Bursting) is "Paused" (you can do this hardcore style within the App's settings too). If you Connect too early, the App may (sim specific) continually override your Race (Session) Screen Onboard Fuel etc. with your in-game settings, which can be infuriating when you are actually trying to plan out your first stint's Fuel load to then setup the same in the SIM.
The App recognises Refuels and so the screen will automatically refresh to the next pit recommendation, ready for you to decide again. No typing, no counting, no guessing, no additional thinking, leaving you to concentrate on... apexes and exits.
Post Race / Race History — Evaluate your performance, further enhance future Races. If the session type is recognised as being a "Race" (there are several recognised types specific to each SIM), then clicking the icon below from the Race Screen...
End Race
...will insert that session's stats into your "Race History". This is done automatically when the Companion App is connected and when you run out of Fuel in Manual mode.
Can also be accessed from the Weekend screen (when you have a history for that Track/Car combo)
Race History
Total Fuel / Margin (Excess) Connected status (🖥️) or a community-sourced result allows Flags and Best Lap inclusion etc.
Connected status (🖥️) or a community-sourced result allows Overall and Class Positioning
Fuel Used / Margin (Excess)
The resulting averages are used on the Grid Stint Fuel calculation, overriding the internal static ratio
Community Racing
If your sim racing community provides post race results, you may be able to update additional values such as laps completed, best lap and start / end positions. This will be more valuable to Manual users - but not limited to - seeing as we don't accept certain user entered data for obvious reasons. So if we can go directly to your community for those results, that would be more trustworthy (it's not that we don't trust you, we don't trust anyone).
Just hit the from the Post Race / Race History screen to kick off this process.
You can upload your race results from your chosen community
The weblink you provide can't be hidden behind a login, our server needs to parse the page to acquire your results.
If your community is not in the list, please get in touch and we will see what we can do.
You Choose
We don’t hand you a fixed pre-race plan and then hope that reality will play along — a rigid strategy will inevitably come unstuck the moment a safety car, a pace change or a bit of damage throws it off. Instead, every pit stop offers its own decision, made easier with the full-lap segments already populated for you. There are three bars, right there on the race screen:
Fuel to FinishShows exactly how much fuel is still needed to reach the chequered flag from right now, updating live as your pace and fuel burn come in — no mental arithmetic, no spreadsheet.
This example shows roughly 3½ tanks are going to be needed overall (long race), it's your choice how that then gets distributed over your pit stops
Tap to FillThe bar is split into full-lap segments, not a free slider — tap the one you want to stage for the NEXT stop. Full laps only, on purpose: any fuel above a whole lap's worth is just dead weight you're carrying round the track for nothing. It defaults to a sensible suggestion (enough to safely reach the flag, or a full tank if the race needs more than one), but you're never locked in. Tap the same spot again to release your choice back to nothing staged (for now).
Full-lap segments free you up to concentrate on driving! Notice how the full-lap segments may not mean a completely FULL tank.
Onboard NowWhat's actually in the tank right now, plus your staged Refuel value — and a clear flag if you're carrying more than you'll actually burn, so you're never guessing whether you're overweight on the grid.
The light green shows the current Onboard Fuel level. The dark green shows what your staged Refuel value would look like
Choose Wisely
The full-lap segments will indicate if you are about to commit a cardinal sin!
The Onboard display will also indicate that you are running far too heavy (you should have taken our advice)!
Every stop is a fresh decision, not a locked-in plan — any pit stop, whether it's the one the app suggests or a splash-and-dash after a safety car, the hard thinking is done for you, just use the staged Refuel value (below) because you KNOW it'll be to full-lap spec.
In manual mode, tapping this icon while in the pit, will auto-fill your onboard with this value.

More simulators are in development. The Companion App is designed to support any sim that exposes telemetry data, so expansion is a question of when, not if.
Console Users
Live Telemetry isn't available for Console users, you have to manually ensure the 2 systems remain in sync (honestly it's not that difficult), including Start Engine and Start Race...
...you then have to manually ensure the numbers stay in sync with what is in-game so that your fuel recommendations also remain realistic and reliable.
The Race Timer automatically counts down (the Live Telemetry merely auto-syncs for PC users), which in turn calculates your running fuel consumption, so the manual tweaking you need to do is usually minimal (can usually be done with a few clicks on Pit Straight).
What it replaces
Mental arithmetic under race pressure, when you've got more important things to be thinking about
Spreadsheet calculators running on a second device
Static pre-race fuel estimates that go wrong the moment your pace changes or you take damage
Future Evaluation of Performance and Fuel Usage for all your previous Track / Car combos
Who it’s for
Solo racers who want one less thing to think about during a race.

About the developer
FinishRaces is built by a sim racer, for sim racers. It started as a personal tool to solve a problem I had every race weekend — remembering how much fuel to put in, under pressure, while also trying to race well. If you have feedback, a feature request, or you just want to say hello, get in touch.
