ALDLdroid is an application for OBD1 GM (ALDL) ECMs. It is currently compatible with both 160 baud and 8192 baud protocols.

ALDLdroid is compatible with TunerPro files (ADX) for data logging, just make sure you have the ADX file for your ECM before purchasing the app. If the app doesn't come pre-packaged 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've started the app for the first time and the folders structure has been created.


The application has also been used beyonds GM ECMs. With the proper XDF file (make sure your file is not encrypted), it can do tuning file editing on other car/motorcycle brands such as BMW N54, Buell, DSM, Ducati, Ford, Holden, Nissan, Porsche, Volvo, Fiat, Renault, etc. Just make sure your can source the XDF file for your application before purchasing the app.

The tuning section uses TunerPro files as well (XDF) to allow editing BIN files. Real-time tuning is currently supported with the Moates Ostrich and the Moates AutoProm hardware. Real-time tuning for NVRAM based ECUs has also been added (only tested with Australian ECUs such as the Delco '808). Chip programming is also possible using the Moates BURN1/BURN2 hardware.


Currently, connection to the ECM can be made using Bluetooth or USB (FTDI). Make sure that your Android device support one of these two connection methods. USB host mode is supported on most devices these days but note that having a USB port on your Android device doesn't automatically means it support USB host mode.


For GM OBD-I, ALDL adapters to connect the application to your GM ECM for data logging can be purchased here if you don't already own one:
- Bluetooth version: http://www.1320electronics.com/products.html or https://reddevilriver.com/ALDL_Bluetooth.html
- USB version: https://reddevilriver.com/aldl.html or http://aldlcable.com/

By double tapping on any page of the dashboard, you enter the dashboard edit mode. That mode allow full customization (add/edit/delete) of the dashboard indicators. You can easily drag indicators where you want them. You can also add indicators in the format you want: gauge, basic readout, bar graph or histogram. Colors can be customized along with some styling. Alarms can be set and once your alarm value has been entered to trigger an alarm, an indicator can be configured to turn red and/or the Android app can vibrate.


The app includes a couple log viewers. One allow you to see your data logs in a scatter plot format where you can select the X/Y/Z axis from columns of your data log files. The second one allow you to see your GPS data on a map and can be merged with the third viewer that is the regular log viewer that can shows time series of data from any columns of your data log files. See screenshots to see all three of them.

No refund can be made after the 15 minutes allowed by Google Play. It would probably be a good idea to check with online communities that use the same ECM as you if they had success with this app before purchasing.


If you're running into any issue with the app, don't panic, just email me and I will try my best to help. Don't write a bad review until you gave me a chance to help :) Note that I might not have access to your exact setup (Car ECM, Android device, etc) so please provide as much information as possible.


I'm not responsible for any damage that could be caused by this app to your vehicle or anything else (although I really don't see how anything bad could happen). Buy and use at your own risks. Drive safe!
