ALDLdroid is an application for OBD1 GM (ALDL) ECMs. It is currently compatible with both 160 baud and 8192 baud protocols. The application has also been used beyonds GM ECMs such as BMW N54, DSM, etc etc. OBD-II support is in there but has not been extensively tested.
It is compatible with TunerPro files (ADX), just make sure you have the ADX file matching your ECM code mask before purchasing the app. You will also need to make sure your ADX file is NOT encrypted as the app cannot read those. You will have to copy your ADX file to the ADX directory of the ALDLdroid folder on the external storage of your Android device once you’ve started the app for the first time and the folders structure has been created. Verify that your Android device has external storage capability (most likely SD card).
