OBD Fusion (Car Diagnostics)

OBD Fusion is an app that allows you to read OBD2 vehicle data directly from your Android phone or tablet. You can clear your check engine light, read diagnostic trouble codes, estimate fuel economy and much more! OBD Fusion has a ton of features that are used by professional car mechanics, do-it-yourselfers, and users who want to monitor car data during day to day driving. Some of the features include customizable dashboards, real-time graphing of vehicle sensors, emission readiness status, data logging and exporting, oxygen sensor tests, Boost readout, and a full diagnostic report.

Is your check engine light on? Do you want to monitor fuel economy and usage in your vehicle? Do you want cool looking gauges on your Android phone or tablet? If so, then OBD Fusion is the app for you!

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.
