Race tune generator

Build a faster base tune.

Enter the car's real weight, horsepower, drivetrain, front weight percentage, tire widths, and track style. DLTuning creates a racing baseline you can test and fine-tune in Forza.

Start tuning How it works

Garage tuner

Use actual in-game numbers. The more accurate your inputs are, the better the baseline tune will be.

Car setup inputs

v2.1
Use the car's real Forza weight after upgrades.
This is front-end weight distribution.

Recommended tune

Baseline
Your tune will appear here. Start with the generated setup, test the car, then use the handling issue dropdown to correct understeer, oversteer, wheelspin, or braking instability.

How it works

This calculator uses Forza-style tuning logic to create a strong starting point, not a guaranteed world-record tune.

Weight based springs

Spring rates are calculated from actual vehicle weight and front weight percentage, so a heavy front-engine car gets different numbers than a lighter mid-engine car.

Handling correction

The handling issue selector adjusts ARBs, camber, damping, tire pressure, brake bias, and differential settings to match the problem you're feeling.

Track + gearing logic

Technical tracks favor rotation and shorter gearing. High-speed tracks favor stability and longer gearing. Rally tunes soften the car and shorten gearing.

FAQ

Is this official Forza tuning software?

No. DLTuning is an independent fan-made tuning helper and is not affiliated with Microsoft, Xbox, Turn 10, or Playground Games.

Why do I still need to test the tune?

Every car, tire compound, upgrade path, and driving style changes the result. This gives a strong baseline, then testing makes it perfect.

Can I add saved builds later?

Yes. The next upgrade would be Firebase or Supabase so visitors can save, search, and share car builds.
