Build profile

Help us understand your car as well as you do

For new builds or existing tunes, plan about 5–10 minutes to work through your combo. We collect these details for deterministic physics and math and to ground our AI in your exact hardware — so setup guidance can be as accurate as possible.

Every field is required so the profile matches your real hardware, except injector part numbers (optional).

One section at a time — go back whenever you like. Exit leaves this flow without saving.
