22 driver-style diagnostic cards covering understeer, oversteer, balance and gearbox.
/About — the story
Built by drivers who finished Rivals top 100
EasyTune started as a private spreadsheet. After thousands of tunes across the Forza series and multiple Rivals top-100 finishes, we turned it into the calculator we wished existed.
The problem
Tuning in Forza Horizon 6 has never been more complex. 600+ cars, 8 disciplines, dozens of upgrade paths. The existing tools were either stuck in 2018, English-only, locked behind subscriptions, or threw raw numbers at you with no diagnostic.
- /01 Manual tuning eats hours in Excel for setups that rarely transfer between cars.
- /02 Existing calculators expect you to already know what an anti-roll bar does.
- /03 No tool reads what you actually feel behind the wheel.
- /04 Most are English-only — the global Forza community deserves better.
The solution
A symptom-based diagnostic. You tell us what the car does wrong in plain language — "the front pushes straight in mid-corner" — and we compute a setup that fixes it.
Calibrated on real FH6 values (spring rate in kgf/mm, differential percent, aero balance).
Per-axis fine-tune sliders for front, rear and global balance.
Six languages, native-translated diagnostic vocabulary.
Who built this
EasyTune is built by one driver with a decade of Forza experience: multiple top-100 Rivals finishes, thousands of tunes shared with friends, hours of telemetry analysis. After watching friends struggle with the same broken setups year after year, the calculator stopped being a personal tool and became EasyTune.
Why open source
EasyTune is MIT-licensed on GitHub. Every formula, every magnitude, every diagnostic mapping is auditable. If you do not trust our numbers, you can read them.
- /01 MIT license — fork it, study it, contribute back.
- /02 Transparent calculations — no black box.
- /03 Independent — no parent company, no investor pressure.
- /04 Privacy-first — no account, no tracking, no data leaves your device.
What is next
The roadmap is community-driven. Pro Android first, then iOS if the demand is real. The blog and glossary grow with reader questions. The diagnostic catalog expands as players surface new symptoms.
01
Pro Android
Full 600+ car catalog, all 8 disciplines, A/B compare, PNG export.
02
iOS
Same scope as Pro Android, shipping if Android traction justifies the build.
03
More languages
Italian, Korean and Polish under evaluation based on traffic.
04
Blog and glossary
Tune guides per discipline (rally, drift, drag) and a growing glossary of tuning terms.
05
Community
Public Discord with shared tunes, leaderboards and the next batch of diagnostic cards.
