A few things to know.
What’s included?
Your selected tuning stage, one supported vehicle licence and an adapter. The app download is free; use your own compatible smartphone.
Will it work with my car and phone?
The MK7 kit covers all Ford Fiesta ST MK7 models. The MK8 kit covers all Fiesta ST MK8 and MK8.5 models. These kits are for Fiesta ST models only. iPhone requires iOS 17 or later; check Android device support with us. App screens show an MK7 example.
How do unlimited tuning changes work?
Use the app to choose from the supported settings and calibrations available for your licensed vehicle, then reflash whenever you want a change. Available options depend on your tuning package. Always use a calibration suitable for your actual fuel and hardware.
Can I change calibration while driving?
No. Follow the guided flashing instructions with the car stationary and the engine switched off. Higher stages may require supporting modifications.
