Optimize your setups & racing strategies on Le Mans Ultimate (LMU) and rFactor 2 (RF2)

📅 Updated on August 2, 2026

AI Engineer: what the analysis now sees

• 🔎 Far more data: The AI Engineer now receives your sector times, tyre temperature across the full tread (inner, middle, outer), per-wheel grip, your throttle and brake inputs, plus oil and water temperatures. Enough to tell you where you lose time, and why.
• More accurate diagnoses: Invalid laps no longer skew the analysed averages — a single off-track moment could quadruple the tyre wear the AI was seeing and completely flip its diagnosis. Suspension data, previously sent in the wrong unit, has also been fixed.
• Inflation issues finally spotted: When tyre temperatures reveal a pressure problem, the AI now tells you, where it used to stay silent.
• Also included: On Premium, the conversation keeps 8 exchanges in memory instead of 3. And the Telemetry pages open instantly, with a loading indicator while the data is computed, instead of freezing for several seconds.
• Why now: The new engine announced yesterday costs less than the previous one. Rather than pocketing the difference, we put it back where you can see it: into what the AI receives, and into how sharp its answers are.

📅 Updated on August 1, 2026

AI Engineer: a new engine, and a clearer display while it thinks

• 🧠 New engine: The AI Engineer now runs on a newer model, selected after a round of comparative testing. Sharper setup analysis, better reasoning behind each recommendation.
• A short thinking phase: This model takes a few seconds to think before writing. That's expected, and it's exactly what lets it give more structured answers.
• For everyone: These changes apply to both the standard AI Engineer and the Premium conversational version.

📅 Updated on July 27, 2026

Community setups: what changes during the free trial

• 10 setups during the trial: During your 14-day free trial, you can now download up to 10 community-shared setups — plenty to explore the library on your favourite cars and tracks.
• Visible counter: The number of downloads left is shown right on the Setups page, so you always know where you stand.
• Unlimited with Premium: With a Premium subscription there's no limit — download as many setups as you want, whenever you want.
• Why this change: These setups come from drivers who choose to share their work with the community. This limit protects that work while still leaving plenty of room to judge the library's quality before subscribing.

📅 Update from May 17, 2026

New feature:

Community setups for Le Mans Ultimate: share your best settings with the community and download those from other drivers in one click, directly from SimHub, with no file handling.

SimHub plugin side:

Community: browse all shared setups, filter by car, track, conditions, or session type, then automatically install the setup in the right place in the game.
My setups: find all your shares, make them public or private at any time, and easily delete them if needed.
Share: select a recent session, let the plugin detect the car, track, and your best lap, then share your setup in a single click.

Website side:

New Setups section: find community setups with the same filters as in the plugin, handy for quickly spotting the settings you are interested in.

Access:

Standard: share your setups with the community without limits.
Premium: download community setups without limits, while keeping access to your own shares.
Free: browse the public setup list to discover what the community offers.

📅 Update of April 8, 2026

Improvements made:

Changelog page: a new dedicated page now lists all updates to Strat Calculator, including minor adjustments, with quick access from the button on the homepage and the footer.
AI Engineer: its behavior has been adjusted so it can suggest tire pressure recommendations only when the request is explicitly made.

📅 Update on March 4, 2026

The improvements made in the AI Engineer:

Interactive Cornering Assistant: Discover a real-time top-down animation to accurately visualize the car’s behavior through a corner. Ideal for understanding at a glance what really happens at turn-in.
4 educational modes: Ideal line, understeer, oversteer, and curb instability: each mode displays a dedicated trajectory with an animated car to instantly compare the differences.
Synchronized dynamic steering wheel: Steering angle, counter-steer snaps, and oscillations are reproduced live to clearly illustrate the driver’s reactions in each situation.
Instant visual understanding: Designed for beginner simracers, this tool helps quickly identify cornering mistakes and build the right reflexes more easily.

📅 Update of February 18, 2026

Improvements made:

SimHub Plugin – Telemetry anti-spam: The minimum delay between two telemetry submissions had been removed, allowing the user to send without restriction. The 10-second delay has been reinstated to prevent spam submissions.
AI Engineer – Microphone usage: Voice input is now cumulative: the microphone deactivates between speech inputs, but when the user speaks again, the new text is appended without erasing what was previously said.

📅 Update of February 17, 2026

Improvements made - SimHub Plugin:

Complete overhaul of telemetry sending: Faster, more reliable, and better optimized upload. Data is now sent in a single request instead of three, reducing transfer time and significantly limiting the risk of errors.
Real-time subscription check: The subscription is now verified at each use. No need to restart SimHub if you subscribe during a session, everything is taken into account instantly.
"Check for updates" button: A new button now appears in the plugin settings to check at any time if a new version is available and launch the update with a single click.

📅 Update of February 15, 2026

SimHub Plugin Improvements:

PTT Engineer in continuous evolution: Its internal operation has been optimized to progressively improve response quality and race analysis, delivering an even smoother and more realistic experience.
Subscription fix in progress: Currently, the subscription check occurs when SimHub starts, which requires a restart after subscribing. This behavior is not intended and will be fixed soon.

📅 Update of February 15, 2026

Improvements made:

Click count indication: The AI engineer now directly indicates the number of clicks to apply to reach the optimal setting, instead of estimating a target value. More precise, clearer, and above all faster to apply during setup.

📅 Update on February 8, 2026

Development status:

Active development: Strat Calculator continues to evolve constantly, with a fully committed team working to keep improving it.
General optimization: Current efforts are focused on improving the performance, stability, and overall smoothness of the tools.
