One price. No per-flash fees. No per-revision charges. We tune your ECU remotely — base tune, datalog refinement, final delivery — until your car gets the Green Light.
Faster than local shops. Data-driven. AI-assisted. Built by tuners, for tuners.
Flash as many times as the revision plan allows. Zero hidden costs.
Base tune in 24–48h. Most cars hit Green Light inside a week.
Every revision is built from YOUR datalogs, not a template.
Hybrid AI + master tuner workflow catches issues humans miss.
Real-time chat with your tuner. No support tickets, no waiting.
We tune until the car is right — within defined safety limits.
Drag your ECU binary into the portal — or plug in your AutoTuner / KESS / BTT and we pull it.
AI + master tuner generate a base calibration from your fuel + hardware + goals. 24–48h.
Flash, drive a structured datalog (idle + part-throttle + WOT). Upload back via the portal.
We refine fuel, timing, boost, knock control from real data. Up to 3 revisions included.
Final calibration delivered. AFR, knock, IAT, LTFT all within target. The car is yours.
Pick your stage. We do the rest until your car is dialed.
The .msq format is open. TunerStudio is open. The community has earned a discount, not a markup. Same AI Copilot. Same unlimited revisions. Same Green Light loop. Just $50.
Most of the cost of a custom tune is locating maps inside a locked OEM binary. MegaSquirt skips that — your .msq is plain XML with named tables. We can read it in 3 seconds. So we charge what the work actually costs, not what the binary puzzle would cost.
Note: MegaSquirt tunes don't need a flashing tool — TunerStudio writes directly to your ECU over USB. So no AI Tuner Pro Flasher needed and no Smart Datalogger needed (TunerStudio already logs). $50 covers the whole job.
