What you feel at the wheel becomes one or two rule-backed changes.
Six cars are open in Beta right now, on tarmac and gravel. Describe what the car does and I'll hand you one or two rule-backed changes. Free — no card, nothing to install.
Tunable right now: Škoda Fabia RS Rally2 · Lancia Delta HF Integrale EVO · Lancia Rally 037 · Citroën Xsara WRC · Peugeot 208 Rally4 · Fiat 131 Abarth — each on tarmac and gravel.
From feeling to fix
Describe what the car does. Get back a structured diagnosis.
Tell Rally Engineer what you feel in plain words. The readout below is a sample — not a reading from your car — showing the shape of what comes back: a problem, a phase, a severity, your preference, the surface, and how confident the diagnosis is, stated in words rather than a number.
- Problem
- Unstable under braking
- Phase
- Entry
- Severity
- Moderate
- Preference
- Wants more stability
- Surface
- Gravel
- Confidence
- High
Changes, inside safe limits
- →Soften the front anti-roll bar one step
- →Move brake bias 1% rearward
How it works
Describe it in plain words
Tell Rally Engineer what the car does — unstable under braking, loose on entry, short on traction.
Answer a few guided questions
Two to six quick questions narrow down the phase, the surface, and whether you want more stability or more rotation.
Get one or two changes
The diagnosis turns into one or two setup changes, inside safe limits — never a full rebuild.
Under the hood
Every diagnosis is built from six fields
Problem
What the car is doing wrong, in the driver's own words.
Phase
Where it happens: braking, entry, mid-corner, or exit.
Severity
How much it is actually costing you on the stage.
Preference
Whether you want more stability or more rotation.
Surface
Gravel, tarmac, or snow — the setup logic differs.
Confidence
How sure the diagnosis is, stated in words, not a number.
Rally Engineer — Pricing
Free while the cars are in Beta
€9.99/month after — or local equivalent. Every Beta car on tarmac and gravel is free to tune: the full session, Garage and history included. When a car graduates from Beta, tuning it joins the Rally Engineer plan.
Free while in Beta. One or two changes. Inside safe limits.
