Neat and Effective OBD Scanner

For the most part I would recommend this app for its simplicity and ease of use, however it doesn't really pinpoint everything down to a tee, but again don't expect a whole lot from just this purchase. There are additional features available for diagnosis but you must pay a little more for those features. This is a neat app that has lots of parameters to look thru like engine temp fuel consumption etc. I scanned my dads truck and it pulled 3 codes which dropped clues as to what was causing rough engine idle and told me which cylinder,etc. I've had connection issues when using the app. Could be my OBD scanner not sure. Great app for general engine diagnosis. 👍😉

OBD Fusion Daily Use

This app has served me well everyday. I did an engine conversion in my 1984 Vanagon to a Ford Zyrtec engine. I use this app on my phone as a dashboard for all critical engine metrics. My van essentially only had idiot lights, this app provides me we with a visual means to see all the OBD data real time on my dash. Very easy to use, easy to see history and connection is automatic as I keep a wifi plug on the ECU at all times.

Unbelievably great app, let alone for free!

Any single of the multiple tools included in this application are really cool.

I would say overall this app is a better data logger, data monitor and gauge/indicator package then it is a diagnostic tool.

As far as BMW diagnostics are concerned, it only gives you the generic errors with none of the proprietary insights that you get from BMW dealership level tools. But for 90% of the users it perfect.

The performance screen is also really cool as well.

I highly recommend taking advantage of the app's dropbox link so that you can download all the data at this application generates onto your PC for both current and historical analysis.

Well done, and thanks a lot!
