What your reports include

Subscriptions include a monthly number of reports you use on either flow below. Each finished run counts as one report toward your included usage (or prepaid balance if you are past the cap). You validate everything on the car and in your calibration software — Crazy Tuner does not push live map changes to your ECU.

Guided base tune (per report)

From the Base tune tab using your vehicle profile — no datalog required.

✓ Deterministic physics and math + AI, grounded in your combo
✓ Preflight checklist and startup strategy
✓ Starter-map direction (e.g. VE, lambda targets, spark) and ECU-area guidance
✓ CSV export for suggested maps where your plan unlocks it
✓ Written first-start plan you verify before relying on logs alone

Log analysis (per report)

From the Analyze tab after you upload and parse a CSV from your ECU toolchain.

✓ AI-assisted read of the log against your vehicle context
✓ Likely issues, confidence, and why those hypotheses fit your channels
✓ Recommended verification steps (fuel, sensors, enrichment, boost, etc.)
✓ Reasoning for suggestions — not blind table rewrites
✓ Safety-oriented guidance on what not to change too early

Pricing FAQ

How is DIY different from Professional?: Both are subscriptions with monthly included reports. Professional includes a much higher monthly allowance for teams and calibrators who run reports every week.
What happens if I use my monthly allowance?: You can buy prepaid reports for the rest of the month from billing. They sit on your account until you use them, or you can wait for the next monthly cycle.
Is there a trial?: DIY monthly includes a 7-day trial before you are billed. DIY yearly and Professional plans do not include a trial.
