OBD Fusion is a vehicle diagnostics tool that connects to OBD-II and EOBD vehicles. Not sure if your vehicle is OBD-2, EOBD or JOBD compliant? See this page for more information: https://www.obdsoftware.net/support/knowledge-base/how-do-i-know-whether-my-vehicle-is-obd-ii-compliant/. OBD Fusion works with some JOBD compliant vehicles and in some cases requires modifications to the connection settings in the app. Please contact us for more information.
You must have a compatible scan tool to use this software. For recommended scan tools, see our website https://www.obdsoftware.net/software/obdfusion. Please note that cheap ELM clone adapters can be unreliable. OBD Fusion can connect to any ELM 327 compatible adapter, but the cheap clone adapters tend to have slow refresh rates and might disconnect randomly.

2024 Update: Please add phone current battery, date, timE as a DISPLAY. I love using this app. However I was in the middle of nowhere, app refused to connect without validating the app. I had no internet access. This needs to be fixed asap. If there is no internet, at least allow the app to run in normal mode.(temporarily disable the enhanced diagnostics). Also my OBD adapter is WiFi, so the enhanced diagnostics randomly get enabled please fix it.

I bought this app specifically for use with Android Auto. I have always used Torque Pro with my bluetooth OBDII device which works great but it isn't listed as an AA app for whatever reason. The AA dashboard is not really a dashboard. It's just simple PID readouts from the vehicle ECU. I want actual gauges just like what is in the phone app to show on the display in my car.

Android Auto does not support custom dashboards and gauges, and we list that in the app description. OBD Fusion has to work within the framework of what's supported by Android Auto. Please reach out to us if you have any questions.

Edit 1/7/25: The change I initially objected to has been changed back to show a green check and "no codes", instead of screen full of text. Much easier to interpret at a glance. However, I'm still puzzled why once we're familiar with an app, apparently unnecessary, or actually counter-productive changes are made. I do really like the app and think it's very functional. I just like to keep it that way. I gave 5 stars for that....and the developer actua listening to users and incorporating input.

The latest update was a large development effort that added a ton of new features and improvements to the app. However, the main layout and organization of the app has not changed, so I am a bit confused by your review. Can you please email us so we can get more information about the problems you are having?
