Five steps to your first connection

  1. 1 Install Apple TestFlight on your iPhone.
  2. 2 Open the TestFlight link and install MOSTUNED from TestFlight.
  3. 3 Connect to the car using an ENET or WiFi-ENET adapter.
  4. 4 Start the connection in the app and check the VIN, ECU and unlock status.
  5. 5 If your car is supported, choose an appropriate flash package. Coding appointments are a separate service.

Flash compatibility

Verified coverage: Turkish-market BMWs with the 1.6L B48B16 (1,597 cc / MG1CS003 ECU) engine — 320i (G20), 420i (G22/G26), 520i (G30) and X3 sDrive20i (G01). Coverage is expanding and will be announced here; ask anyway if your car is not listed.

The broader BMW coding catalogue does not mean that every model supports mobile flashing. Check eligibility before buying.

Before flashing

Check vehicle and phone power. Follow the preparation steps in the app, ensure a stable connection and keep the adapter connected throughout the process. If the app reports an error or compatibility warning, contact support before proceeding.

Connection and support

What if my car won’t connect?

Check the adapter and selected network connection. If the issue continues, send support your car model, iPhone model and error screen.

What if the ECU is locked?

Let’s assess the unlock requirement before flashing. Explore the unlock service.

Are coding services included in the app?

Feature coding, transmission and M Track services in this catalogue are separate appointments. App flash packages are priced separately.
