Analyze and improve your setup on Le Mans Ultimate (LMU) and rFactor 2 (RF2)

On Le Mans Ultimate (LMU) and rFactor 2 (RF2), setup work can quickly become frustrating. You change a parameter, run 5 laps, compare lap times, and have to guess whether the car is actually better or if it's just your driving. Without a dedicated tool, the analysis often comes down to feel.

Strat Calculator simplifies this workflow: your telemetry and setup are collected through the SimHub plugin and analyzed directly on the platform. You get concrete tuning advice from an AI specialized in simracing, without leaving your rig.

Four clear steps, identical for both games:

1. Run a session in Le Mans Ultimate or rFactor 2, with SimHub running in parallel.
2. Upload the session manually via the dedicated button in the SimHub Strat Calculator plugin or via a configurable shortcut in SimHub (keyboard key, wheel button, etc.) (this avoids unnecessary uploads after every test session).
3. Log in to Strat Calculator to view the recorded data (full telemetry + setup used).
4. Analyze and adjust through the Telemetry and AI Engineer tools.

The plugin is optimized for rFactor 2 and Le Mans Ultimate: it handles each simulator's specifics with no extra configuration on your end.

Once the session is uploaded, your telemetry is available on the Telemetry page of Strat Calculator. You'll find the data collected lap by lap.

• Fuel consumption average and per lap
• Lap times: best, average, standard deviation (consistency)
• Pace evolution across the session (tire degradation, fatigue)
• Setup used for the session: all car parameters saved

Reading this data helps identify weak points before asking the AI for advice: do you have a consistency problem? A tire degradation issue? A pure speed deficit? The angle of attack depends on the initial diagnosis.

The AI Engineer is an artificial intelligence trained on simracing tuning principles. You describe your issue in plain language, just like talking to a real race engineer.

Concrete example questions:

• "My car understeers on the exit of fast corners on LMU, how can I fix it?"
• "My rear breaks loose under braking into chicanes, which parameters should I adjust?"
• "I'm losing top speed on rFactor 2, is it an aero or gear ratio issue?"
• "My front tires overheat after 8 laps, what settings should I try?"

The AI suggests concrete adjustments: camber, tire pressure, springs, anti-roll bars, wings, gear ratios, differential... It also explains why each adjustment addresses the described problem.

You're driving at Spa-Francorchamps with a Toyota Hypercar in endurance on Le Mans Ultimate. Your practice times were good, but during the race you lose about 0.5s per lap. You feel like the rear of the car breaks loose as soon as you load the brakes going down to Eau Rouge.

The typical workflow:

1. You finish the session and trigger the upload via the dedicated button in SimHub (or via your configured shortcut: keyboard key, wheel button, etc.).
2. On Strat Calculator, you open the Telemetry page: fuel is stable but lap time standard deviation is high over the last 10 laps → consistency issue confirmed.
3. You open the AI Engineer and describe the situation. In Premium, you import telemetry + full setup in one click.
4. The AI suggests: slightly increase rear tire pressure, stiffen the rear anti-roll bar by one notch, check the differential coast ramp.
5. You apply the changes in-game and run another session to validate.

No guessing, no endless back-and-forth: a clear diagnosis, concrete actions.

Le Mans Ultimate and rFactor 2 share the same physics engine (ISI / Studio 397). Tuning principles (camber, pressure, springs, anti-roll bars, aero, differential) are nearly identical between the two games.

• One SimHub plugin for both games: no switching, no double configuration
• One analysis platform: your LMU and rF2 session history is centralized
• An AI that knows both games and adapts its advice to the context
• 100% identical workflow: what you learn on LMU applies directly to rFactor 2 (and vice versa)

For drivers who play both games (multi-title competitions, hybrid leagues), this is a major time saver.
