FH6 Tune Pro reads your car, watches you drive, and tells you the exact Forza slider values to change — springs, dampers, ARBs, diff, the works. 618 cars. Free to start.
Hit Record, drive a corner, and the AI reads what your car is actually doing — sliding, pushing, bouncing, snapping — then hands you the changes in real Forza values. Or Capture & Analyse a single screen mid-race.
Half of it is free. The AI and live features unlock with Pro.
Pick any of 618 cars (or enter your own stats) and get a full baseline tune — springs, damping, ARBs, alignment, tyres, brakes, diff, aero.
Tell it what the car's doing wrong and get the exact slider changes — no AI, no internet, instant.
Save, reload, compare and share full tunes with share codes. Build your collection.
Every ratio, mph-at-redline per gear, and the RPM you drop to on each upshift — with live detected gearing as you drive.
Rate what the car's doing on a slider and get rule-based fixes free — or ask the AI coach to tailor changes to your exact setup.
Real data from Forza — speed, RPM, power, tyre temps, per-wheel grip, G-force, lap times — with a rolling 5-second diagnosis.
Record 30 seconds of driving and the AI tells you exactly what to tune. Pick Haiku, Sonnet or Opus to balance cost and depth.
It reads your car straight from telemetry and links it to your tune — no manual picking.
Bring your own API key. The app shows the cost per request and what a deposit buys — no markup, no AI subscription.
One Windows app. No installer headaches, no account to create.
Search 618 cars, or let telemetry detect it live while you drive.
Copy the numbers straight into Forza's tuning screen. Drive. Let the AI refine.
Start free. Go Pro for the AI & live features — pick the length that suits you.

Yes. The warning is just SmartScreen flagging an app from a small, unsigned publisher — it has nothing to do with viruses. Click More info → Run anyway. We're working on code-signing to remove the prompt, and you can always ask in Discord first.
It's built and tuned for Forza Horizon 6. The live telemetry uses Forza's data-out feature, which is shared across recent Forza titles, but the car list and tuning is FH6-focused.
Two ways. On Pro, bring your own Anthropic API key and pay the raw model cost — no markup. Or go Pro + API and we manage it for you: deposit credit (+20%, $5 minimum) and there's no key to set up. Either way the app shows the exact cost per request, and you can switch between a cheaper model (Haiku) and a smarter one (Opus) any time.
No. It never touches the game files or memory — it reads Forza's own telemetry broadcast and reads your screen, exactly like any overlay or capture tool. You still enter every tune by hand in Forza.
