What's in one $39 tune
A complete guided session for one car — start to verified.
Vision reads your VCM Editor injector, MAF, spark, fueling and rev-limit tables straight from screenshots — exact values, units preserved.
Every table checked for lean WOT, aggressive timing, injector/part mismatches, MAF saturation and unit traps — flagged 🔴 critical / 🟠 caution / ✅ good.
Not vibes — the specific cells and copy-paste values to set, ordered safety-and-reliability first, with the reason and the unit trap called out.
Upload a VCM Scanner pull and TuneVault checks commanded vs delivered AFR, knock retard, fuel trims and IAT — a clear go / no-go before you trust it under boost.
The whole session — tables, audit and the plan — is saved to the car, so you can come back, revise, and roll back to last known-good.
Which plan is right?
Per Tune vs Garage vs Pro vs Shop — in one line each.
A single, complete guided tune for one car with one datalog verification pass — perfect if you just need to get this one build right.
Monthly plan for the hobbyist: up to 3 tunes a month and unlimited datalog re-checks on your own cars as you dial them in over weeks.
For active tuners and e-tuners doing volume — up to 10 tunes a month, unlimited log analysis, and a faster, deeper priority Copilot.
For a bay tuning customer cars: unlimited everything, multiple tech seats, customer/vehicle records, and a shared safety checklist.
Pricing questions
What exactly is included in one $39 tune?
A full vision read of your VCM Editor tables, a complete safety audit with severity flags, an exact ordered copy-paste change list, and one datalog verification pass to confirm it's safe — all saved to your garage. It covers one vehicle.
What is a 'datalog verification'?
After you flash your changes and do a VCM Scanner pull, you upload the log and TuneVault checks commanded vs delivered AFR, knock retard, fuel trims and IAT, then tells you whether it's safe or what to change next. Per-Tune includes one pass; monthly plans include unlimited re-checks on your cars.
How do revisions work?
Tuning is iterative. On monthly plans you can re-audit tables and re-check datalogs on your saved cars as many times as you need. On Per-Tune, the guided session and one verification pass are included; further verification passes are covered by any monthly plan.
What's the difference between the plans?
Per Tune is one car, one time. Garage (3/mo) suits weekend builders. Pro (10/mo) is for active tuners who do volume and want a faster, deeper Copilot. Shop is unlimited with multiple tech seats and customer records.
Is this a replacement for a tuner?
No. TuneVault is a copilot that gives tuner-grade analysis and exact, conservative changes — you (or your shop) still make the call and flash the car. For high-boost or unusual builds, a qualified human tuner is still valuable, and it never guarantees horsepower.
Why is it cheaper than a dyno tune?
A custom dyno tune is $300–600 because of a tuner's time and dyno hours. TuneVault automates the analysis, so you get the expertise for a fraction of the cost. You provide the car, the flash, and the wideband verification.
Can I cancel anytime?
Yes. Monthly plans cancel anytime from your account; Per-Tune has no commitment at all.
- •TuneVault is a tuning copilot, not a replacement for a professional tuner. For high-boost, forced-induction, or unusual builds, a qualified human tuner is still valuable.
- •No tool can guarantee horsepower. Power depends on your hardware, fuel, altitude, and condition — anything promising a number is selling you something.
- •You are responsible for what you flash. You make the changes and write them to your ECU; the outcome is yours.
- •Commanded AFR is not delivered AFR. Always verify fueling with a wideband before boost, and keep timing conservative for pump gas.
- •Modifying emissions equipment may be restricted where you live. Know your local laws; off-road/competition use only where applicable.
