ECU Tweaker is an application for Android devices that allows you to change the configuration of your car using a standard Bluetooth ELM327 adapter (with the original PIC18F2480 chip).
Unlike the PyClip application, ECU Tweaker works with the ddt base.

Installing the application is normal, downloaded and installed. Only then you need to independently write the ddt database to the root of the internal or external memory of the device. The zip archive with the base should be called ecu.zip and nothing else. The database itself (ecu.zip) can be taken from the latest ddt4all builds for Windows. It is located in the folder with the installed program. Or here is the latest, today, base ecu.zip.
The connection to the computer is normal. Almost the same as with ddt4all.
Press the magnifying glass button, select the desired vehicle and then select the desired ECU (ESP, AIRBAG, etc.) from the list. Or AUTO IDENTIFY, so that the application chooses the appropriate ECU file by itself.
Initially, the application is available only for viewing the vehicle configuration and does not allow changing anything in it. To unlock this function, you need to contact the author and send him the "request code", after which he will send an activation code.
To find out your "request code", click on the lock icon.
P.S. And further. The application is in beta testing and should be used with caution.
