Great! Must have for the basic family handyman

While I admit I'm not a mechanic, I've taken some classes over the years, worked at a racetrack and I've worked on cars off and on my whole life(I could never afford to take my cars to a mechanic, so most basic stuff I had to learn) . This with a Bluetooth reader will save you hours of troubleshooting and tons of money. Well worth it.

P0307 code diagnosed

Rough running Ford F-150. Youngest son stationed in Germany turned me on to OBD Fusion app. Downloaded to iOS and ran diagnostics. Found misfire on cylinder 7. Changed ignition coil and fixed problem. No further issues. OBD Fusion is way to use and saved me from the mechanic. More than paid for itself. Highly recommend giving this gem a try. You won’t be disappointed. Go Army!!!

This OBD is great to use. I feel it’s accuracy is top notch. Well worth the money!! Don’t be fooled by its small size, you get a lot of power for the punch.

Doesn’t work with 09 Honda Fit waste of money.

Bought it in hopes of getting an ECT and oil pressure reading but the app won’t even connect to my new bafx WiFi obd2 access port.

Disappearing PIDS

Each consecutive “update” I lose more PIDs that I monitored. They are not available in another section they are gone altogether. Trans Temp Oil Temp Learned Octane This is just the three I can remember, I have lost so many.

Worked good as the high priced computer on my 3 vehicles.

App doesn’t even detect tpms errors. Tpms light is on and this app can’t even tell me anything.

Very impressed!

This app is a MUST HAVE for the EFI enthusiast! Read and clear codes, GPS map, my favorite part is the PID monitoring! As the owner of East Coast Fuel Injection and GM fuel injection specialist I highly recommend this app to everyone novice or expert. A note to the developer: when editing size and configuration of any gauge the curser gets stuck past the value to edit and will not back space. Which makes it hard to put the curser exactly after the last digit. Also I’d like to suggest double tap gauges to edit rather than hold. Thank you and Bravo to the development team!

Add Ons

No Add On available for GM. Can’t read my ABS codes.

I love you.

Thank you for keeping this app updated. Will continue to recommend this app to fellow “mechanics” 😊
