Help make pit plans accurate: send your race results 🛢️

What this is for

Every briefing sets a Fuel Usage (Real, x2 or x3) so a race gets the pit stops it should, for example one stop near halfway in a 1-hour race. To pick the right setting, Factory Seat has to know how long a full tank lasts.

Right now it uses one number for every car and track: 50 minutes at Real. That was a placeholder I never measured, and it's wrong in places. A player's LMP3 race at Imola went past an hour on one tank, so the planned stop never came. Thanks for reporting it!

Where the numbers stand

LMU's results files record how much fuel and Virtual Energy every car uses on every lap, AI included. I went through 288 of my own race files and worked out the median tank time for each class and track (green-flag laps only, with usage adjusted for the race's Fuel Usage setting). Some examples at Real:

	Tank lasts
GT3, Le Mans	~44 min
GT3, Sebring	~50 min
GT3, Laguna Seca	~64 min
Hypercar, Daytona	~48 min
LMP2, Spa	~45 min

So the track matters as much as the class, and 1.2 will use a table of class × track instead of one number.

Why I need your help

• Gaps. I have no LMP3 data at all. My GTE files are over a year old. Many class and track pairs come from a single race.
• Different drivers, different cars. More races from more players means the medians reflect how LMU actually runs, not just my setups.
• Checking the AI numbers. I'll also drive full-push laps myself to make sure AI fuel use matches a human's.

What to send

Results files from offline races only (any length, any class), especially:

• LMP3, anywhere
• Hypercar / LMP2 at tracks other than Le Mans, Daytona, Sebring and Spa
• GT3 at less common tracks

Every AI car in a race counts, so a few races help a lot. You don't need to send your whole folder.

The files are in Le Mans Ultimate\UserData\Log\Results, named by date and time (e.g. 2026_10_15_00_19_44-93R1.xml). Zip the ones you want to share and attach the zip here.

Privacy, and how to remove your name

GitHub attachments are public. A results file contains:

• your in-game driver name
• the folder LMU is installed in (for example C:\Program Files (x86)\Steam\steamapps\common\Le Mans Ultimate). If you installed it inside your user folder (C:\Users\<you>\...), that includes your Windows username.
• the AI names, the track, the car and lap data

It has no Steam ID and no account info. Online races also contain other real players' names, which is why I'm asking for offline only.

To take your name out before sending:

1. Copy the files you'll send into a new folder (leave the originals alone).
2. Open a file in Notepad and press Ctrl+H.
3. In "Find what" type your in-game name exactly. In "Replace with" type Player. Click Replace All.
4. If your install folder shows your Windows username, do the same with that username.
5. Save (Ctrl+S), then repeat for each file.

Both only appear as plain text, so nothing is left behind.

Credit

If you'd like to be thanked in the 1.2 release notes, say so in your comment and tell me what name to use. If you don't say anything, I won't list you.

Open until the 1.2 beta. Thanks for helping! 🏁

can I attach my result file directly to this comment?
rFactorXML version=1.0.zip

[factoryseatlmuapp]

Yes, that works perfectly, thanks! 🙌 Your Lusail race (18 GT3 + 17 Hypercar) is only the second race I have there, and it shows a full tank lasting a few minutes longer than my numbers. It'll go into the tank table for the next update. More offline races are still welcome, LMP3 especially. If you'd like a thank-you in the release notes, just tell me what name to use

Glad to be of any assistance. This is a great addition to LMU. I will say one negative. I FORGOT TO PRESS THE START THE WEEKEND button in the app before launching LMU. So a great race on my part..didn't get activated. I also had a crash report from LMU at the end, but didn't notice anything out of the ordinary. The Start the Weekend button was partially obscurred by the notes.

[factoryseatlmuapp]

Thanks, that means a lot! Sorry about the lost race. Right now only races after you press Start race weekend count, which keeps test drives and online races out of your career, but it shouldn't be that easy to miss. Could you post a screenshot of the briefing where the notes cover the button, plus your screen resolution / Windows scaling? I'll fix the layout in the next update. On the crash report, Factory Seat only reads LMU's results folder after the race, so it shouldn't be involved, but if it happens again with the app closed, that would confirm it's on LMU's side.

[davehenrie-ICR2]

It was my fault, I just started the next weekend from the main menu and then launched LMU. I only saw the button when I exited LMU. But upon the next launch it was waiting for me to start LMU, so I ran a single practice session and that reported properly to the race engineer. So all good, user error. I did stretch the original image vertically when I posted over at the LMU forum about FS.
(do you call FS an app or utility???)
I appreciate your efforts for the community.

Glad it's sorted, and thanks for the follow-up! You're not the only one. Someone on Reddit missed the same step this week, so it's clearly too easy to miss. One idea I'm looking into is letting you start the weekend from an in-game overlay, so you don't have to tab back to the app. No promises yet, but it's being investigated. And thanks for posting about it on the LMU forum, that's awesome. 🙌 As for app or utility: it's an app, a career-mode companion app for LMU.
