Turbo Boost Lab V1.3.0

New Aero tab to tweak downforce and drag straight from TBL.

Extreme camber unlocked down to -12° for a proper aggressive drift look. Keep in mind the visual result still depends on the limits set by the mod creator, so some cars won’t react fully.

Wheel offset, to widen the front or rear track and work on your stance.

Switching a naturally aspirated car to a turbo one, in a single click.

Updating an already saved tune, with the Ctrl+S shortcut to make it quick.

And the built-in guide translated to 6 languages: English, French, German, Spanish, Italian, Portuguese.

Plus a bunch of fixes under the hood.

Happy tuning everyone.

v1.2.8

I wanted a simple way for you to tell me what you’d like to see in TBL. It’s now there.

Nouveau bouton 💡 dans la barre supérieure. Cliquez dessus et dites-moi ce qui manque, ce que vous aimeriez changer, ou toute autre amélioration qui vous vient à l'esprit. Je lis chaque message et il arrive directement dans un canal dédié où je peux centraliser toutes les idées pour orienter le projet. Disponible en version gratuite et Pro, sans différence : plus on est de fous, plus on rit !

I’ll also pop this window up automatically once a month for people who didn’t think of clicking, but with a seven day grace period at the start so I don’t bother you right after install.

Dans la fenêtre « Signaler un bug » : vous pouvez désormais joindre une capture d’écran. Collez-la directement (Win+Maj+S puis Ctrl+V) ou utilisez le bouton Parcourir. Cela facilite grandement la compréhension des bugs visuels dès le premier coup d’œil.

The rest of the update is stability and a few small adjustments along the way.

Thanks to everyone who writes in, it means a lot.

v1.2.7

Just one new thing this time, but it really changes how you tune : a magnet tool on the power curve.

Until now, adjusting the curve meant grabbing each point one at a time. On cars with many points it got tedious fast, and shaping a specific dip or peak took a lot of back and forth. Now you just click and drag directly on the graph : the curve is pushed away locally around your cursor, like a real magnet with reversed polarity. You can carve out a section, lift up the next one, flatten a plateau — all in one gesture.

Per-point dragging is still there, nothing was taken away. This is just a smoother way to shape the curve for people who like working fast.

The rest of the update is stability and a few small fixes. Thanks to everyone who reports issues, it really helps.

v1.2.6

Two new things this update:

Expert Mode — a new toggle in Settings → Display. Once on, the sliders show the raw .ini values instead of percentages (LAG_UP, INERTIA, POWER, COAST…). Made this for the modders who kept asking to see and tweak the actual values.

Real physical units on Gearbox and Diff sliders. No more "50 % of what?" — shift times are in ms, RPM windows in rpm, clutch torque in Nm, preload in Nm. Works in both modes.

Rest of the update is stability and polish. A few silent bugs squashed, a few rough edges rounded off. Big thanks to everyone who wrote in with reports — keep them coming.

Just pushed a small update that fixes a few bugs some of you were running into. Nothing new feature-wise, just cleaner and more reliable under the hood. Recommended for everyone.

The update installs itself automatically from within the app. If for any reason it doesn't, you can grab the new version manually from this page.

Thanks for the feedback that made this possible!

Big update focused on multiplayer support and workflow polish.

New: Online Mode
One click resets all your cars to their original state so they pass server checksums (multiplayer-ready). A second click restores all your tuning setups automatically. Your current car is prioritised — it's back in seconds so you can keep working while the rest is restored in the background.

New: Car preview on hover
Hover over any car in the browser for 1 second and see its specs instantly (power, weight, hp/ton, drivetrain, gearbox, turbo/atmo). Long names auto-scroll. No click needed.

New: Content Manager setup on first launch
The onboarding now asks where your Content Manager is right after picking your Assetto Corsa folder — no more manual pointing later.

Stability fixes
Fixed the infinite loading spinner some users had at first launch (Free/Pro conflict). "Check for updates" button in Settings now actually works. Content Manager path is editable from Settings. If CM can't be found when clicking Drive, you're prompted to select it directly instead of getting an error.

Enjoy, and thanks for the continuous feedback 🏁
