What does ST Premium include?
Tuning and autotune from the STuner app, the GPS meter, proven base maps, videos and technical info, special discounts in the store and on courses, and premium WhatsApp support. Coming soon: the Wiring Builder with interactive wiring diagrams. The content grows every month.
How much does it cost and how do I pay?
$5 a month or $45 a year (save $15). You pay by credit or debit card through ONVO and it renews automatically; you can cancel anytime from your account.
Is there a free trial?
Yes: 5 days with everything included. You add your card when you start and nothing is charged until day 6; we email you a day before. If you cancel before then, you pay nothing. One trial per person and per card.
How do I cancel?
From My account, with the “Cancel automatic renewal” button: one click, no calls or forms. You won't be charged again and you keep access until the end of the period you already paid. If you also want to delete your account and your data, go to My account → Your account → “Delete my account”.
Is it the same as the Tuning School?
No. The Tuning School offers full wiring and tuning courses, each priced on its own. ST Premium is the exclusive content membership — and being a member gets you a discount on those courses.
Do I need a SpeedTech ECU?
For the app features, yes: tuning, autotune and the GPS meter work with the ST Mini, ST-02 and ST-04 with SpeedTech's Bluetooth module. The rest of the content works for anyone, but it's built around our ECUs.
