Ratings and Reviews
Good program, needs some work
This works well with my OBD2 dongle. The information seems accurate and helped me when buying a used car by showing me the error codes, which I showed the dealer. He then gave us a new battery based on the report with no change in the price of the car.
There are a few annoyance. It does not connect with the Bluetooth with out some finagling. Once the phone is turned off, it loses the connection. The data does not seem to be saved. Once I use it on another car, the data for the first car is lost (or I can’t find it). It “forgets” vehicles so I have to to re-enter the information when I change cars. It would be nice to be able to download the information to a desktop for storage.
Overall works well for diagnostic information but it would be nice to store each car’s information and be able to reference it later.
So I've edited my review an added 3 stars, and here is why: customer support and their ability to respond to reviews to address concerns, big plus here, it shows they are actively aware and engaged in making the app better. Second while you have to go through menus to activate them, there are additional PIDs for ford and gm. If those weren't available, this would of been a deal breaker for me. Third, the app is updated regularly and looks modern with digital readout gauges.
Overall as long as it proves to be as accurate as dash command I'll make the switch.
One thing I would like to see in the future is min max values on the digital read out gauges in addition to current values.

OBD Fusion doesn't have enhanced diagnostics for GM, but it does have some GM specific PIDs that you can import including knock. Open Settings > User-Defined PIDs and press Menu > Import built-in PIDs.
Great IOS App
This app helps me monitor my selected PIDS(engine sensors) that I can choose from many of my engine sensors. The app is very quick to detect my OBD connected to my Ford 2004, V 10, 6.8 L, Motor Home engine. It is very helpful to monitor my fuel usage, and gives me an optimum vehicle speed. The PIDS are easy to select, and you can set over all trip log engine data. All pages are easy to follow, menu selections. Creating, and moving engine sensors, and their design, color, and position, on the user designed Dashboards, are very easy. This IOS app is well worth the App Store price, and quickly pays for itself. I am very pleased with this extreme user friendly app. I highly recommend this app.
