The telemetry tool for Le Mans Ultimate. Record your sessions, compare laps with every driver on the platform, and run in-game HUD overlays (dashboard, delta, track map) to see where you're gaining or losing time.
Free with Twitch Prime · Windows 10/11
Capabilities
From session recording to online lap comparison and in-game overlays, LMU Trace covers the full LMU telemetry workflow.
Record real-time telemetry directly from Le Mans Ultimate: throttle, brake, steering, RPM, speed, tire temps and more. Every lap uploads automatically when you cross the line, with no manual export step.
SimHub-style overlays built natively for Le Mans Ultimate: dashboard, live delta, track map, standings and pedal inputs, rendered directly over the game. Drag to position, pull edges to resize. Works on a single screen or a second display.
Compare your laps against any driver on the platform: lap delta, racing line, pedal inputs and steering all overlaid on interactive charts. The MoTeC-style lap comparison workflow, built for LMU and running in your browser.
High-fidelity SVG track maps generated from real LMU driving data. In-game track map overlay shows live position; in the web app, compare your racing line against any other lap on any mapped circuit.
Every LMU practice, qualifying and race session is saved with full lap data. Browse your history, track consistency across stints, and revisit any lap to analyze your driving data.
LMU Trace is completely free. The only requirement is a Twitch Prime subscription to our channel — and with Amazon Prime, that sub is included at no cost every month. No monthly fees, no license, every feature for every driver.
Overlays
Every overlay is drag-to-position, resizable by pulling its edges, and runs directly over the game on one screen or a second display. Pick what you need, hide what you don't.
Grid-based info display with configurable data boxes — speed, gear, lap, position, delta and more, your layout.
Live track map rendered from real driving data. Shows every car with class colors.
Lap delta bar with throttle and brake traces. See instantly where you're gaining or losing time.
Live speed, gear, pedals, RPM and a rolling throttle/brake trace — the classic HUD, modernized.
Full race standings with gaps, best laps and position changes across the entire field.
The cars around you, ranked by time gap — who you're catching, who's catching you.
Energy and fuel tracking — laps left, usage per lap and refuel target for your next stop.
Tyre temperatures, wear and pressures plus brake temps — all four corners at a glance.

Live conditions: air and track temp, wind direction and speed, and track wetness.
Per-corner damage, suspension health and impact events — critical for endurance racing.
Session type, real-time clock, session time remaining and laps left.
Lap times, stint tracking and position over the long haul.
Focused view on the car ahead and behind — their gap, their pace, your opportunity.
End-of-straight top speeds and corner minimum speeds — benchmark yourself corner by corner.
LED bar for lift-and-coast targets plus live TC and ABS activity indicators.
Clear visual alerts for green, blue and yellow flags so you never miss a call.
Lap Comparison
Pick your lap, pick a reference — yours or anyone on the platform — and see where the time goes, corner by corner.
Workflow
No complex setup. Just drive, upload, and learn.
Run LMU TraceHUB alongside Le Mans Ultimate. It captures throttle, brake, speed, steering, RPM, and position data in real time.
When you cross the finish line, each completed lap is automatically sent to the server. No manual export or file management needed.
Open the web app, pick any two laps, and instantly see where you're faster or slower. Zoom into corners, check braking points, and find time.
From the grid
Sim racers use LMU Trace every day to record laps, compare telemetry and find time. Here's what that looks like.
Overlaid my lap on a driver half a second quicker and the delta trace showed it instantly — I was lifting way too early into the Ford chicane. Found four tenths the same evening.
The track map next to the telemetry finally made the numbers make sense. I can point at exactly where on the circuit I'm losing time instead of guessing.
Runs in the background and every lap is just there when I get out of the car. No MoTeC export, no faffing about. This is what I wanted for two years.
The live delta overlay in-game is dangerously good. I know I'm up or down before I even finish the lap. My braking points have never been this consistent.
Set it up in about three minutes with the Discord login. No plugins, no config files to edit — it just started recording.
Compared my throttle trace to a quicker teammate and the difference was obvious — he was flat twenty metres earlier out of the last corner. Copied it, gained two tenths.
Opening any lap from a three-hour stint later and actually studying it changed how I practise. The whole session archive is gold.
The pedal and steering overlays showed me I was fighting the car mid-corner with tiny corrections. Smoothed it out and the tyres last noticeably longer now.
Standings overlay plus live delta means I barely glance at anything else during a race. Feels like a proper broadcast HUD, on my own screen.

Why €2.99 helps more
With Twitch Prime, Amazon and Twitch keep a large cut of every subscription. A €2.99 direct subscription skips the middlemen — so far more of your money actually reaches us and funds new features.
Already have Amazon Prime? Then it costs you nothing.
Twitch Prime (Prime Gaming) is included with Amazon Prime and gives you one free channel subscription every month. Use it on our Twitch channel to unlock LMU Trace — no payment, ever. Prime subs run month to month, so just re-subscribe with Prime each month to keep your access.
Get it on DiscordWhy we ask for a sub
Running LMU Trace costs real money — computing power to process your laps, storage for every sample of every session, and time to build new features. A Twitch Prime sub covers all of that at zero cost to you, because Amazon Prime already includes it. Want to give more? The €2.99 direct sub puts more in our hands than Prime does. Built by sim racers, for sim racers — every feature exists because a driver needed it.
Community-driven
LMU Trace isn't built in a vacuum. Every driver gets a direct vote on the roadmap — and the highest-voted ideas are what we build next.
No product managers behind a firewall deciding what's worth your time. The roadmap is public, the votes are yours, and the next feature ships because the community asked for it.

Join the DiscordLMU Trace is a telemetry tool built natively for Le Mans Ultimate. It records your driving data directly from LMU's shared memory, lets you compare laps with every driver on the platform, and provides customizable in-game HUD overlays (dashboard, live delta, track map, standings). Unlike general tools like SimHub or MoTeC, LMU Trace is designed specifically around Le Mans Ultimate.
Yes. LMU Trace provides online lap comparison for Le Mans Ultimate. You can overlay two laps on interactive charts (speed, throttle, brake, steering, RPM) with delta time, racing line visualization, and pedal inputs shown side by side. Compare your laps against your own session history or against any other driver on the platform.
Yes. Install LMU TraceHUB on Windows, log in with Discord, and it automatically records every practice, qualifying and race session from Le Mans Ultimate. Each lap is uploaded to your account when you cross the line, with no manual export step. Your full session and lap archive is then available in the web app.
LMU Trace ships SimHub-style overlays built natively for Le Mans Ultimate: a dashboard overlay, live delta overlay, track map overlay, standings, pedal inputs and more. Overlays render directly over the game, are drag-to-position and resizable by pulling their edges, and work on a single screen or a second display. No SimHub installation required.
Record your session with LMU TraceHUB, then open the LMU Trace web app. Pick any lap to inspect speed, throttle, brake, steering, RPM, and the racing line on interactive charts. Overlay a reference lap (yours or another driver's) to see where you're gaining or losing time corner by corner, and use the track map to correlate chart data with physical track position.
Record your laps, find a faster reference lap, and compare the two on telemetry. LMU Trace gives you a lap delta, racing line comparison, and pedal input overlays so you can see where a faster driver gets on the throttle earlier, brakes later, or carries more speed through a corner. Then copy that technique lap by lap.
LMU Trace is easier to set up than MoTeC and comes with modern overlays.
