ETflash

ETflash is an application for working with supported vehicle control units via a compatible BLE OBD adapter.

Key features:
• Connection to a compatible BLE adapter;
• ECU/TCU identification;
• Working with protected ETU license files;
• Writing supported ECU/TCUs using the selected protocol;
• Identification verification before writing;
• Real-time ECU/TCU logging;
• Offline CSV log viewing;
• Customizing presets, warnings, and parameter display settings.
• Reading errors

This application is designed for users who receive prepared license files from ETflash/ETuners or the administrator. The application itself does not sell digital content and does not contain in-app purchases.

Important safety requirements:
• Use only the appropriate file for the specific vehicle and control unit;
• Ensure stable power supply to the vehicle and phone before writing;
• Do not disconnect the adapter or close the application during writing;
• Do not flash if the ECU/TCU is not original, has been cloned, has unknown modifications, has been modified with the immobilizer, or raises any doubts about its identification.

An incorrect file, unstable power supply, or loss of connection during flashing may cause the control unit to malfunction.
