ALDLdroid is an application for GM OBD1 (ALDL) ECM. It currently supports the 160 baud and 8192 baud protocols. ALDLdroid supports TunerPro (ADX) files for data logging, just make sure you have the ADX file for your ECM before buying the app. If the app doesn't come pre-packed with the ADX file you need, you will need to add your file to the ADX directory of the ALDLdroid folder on your Android device once you have started the app for the first time and the structure folders have been created. The app has also been used beyonds GM ECM. With the proper XDF file (make sure your file is not encrypted), you can edit tuning files on other car / motorcycle brands like BMW N54, Buell, DSM, Ducati, Ford, Holden, Nissan, Porsche, Volvo, Fiat, Renault etc. Just make sure you can get the XDF file for your app before purchasing the app.
