I have diagnosed and repaired several vehicles over the years I have had this application. On my Dodge Charger it even specified which wheel speed sensor was bad, right rear. No guessing just replace the part and roll on.

Connected to LELink OBD-II easily but always reported that it was “Busy” when I tried to pull codes.

Not the snazziest interface, but it’s the only iOS app I’ve found that properly handles custom pid files, a la Torque Pro. Invaluable for pulling diagnostics on my Chevy Bolt.

This should’ve been obvious to me front he description, but this app doesn’t appear to work with the OBDLink MX+ Bluetooth adapter. I think that’s because the MX+ uses full-speed Bluetooth, not BLE.

The technicians at K Solutions provided unheard of factory support toward helping me create a workable PID for their EngineLink - OBD2 app on my iPhone. After trying several apps and OBD 2 sensors, the EngineLink app provides the trans fluid temp data I was hoping I would be able to obtain for my 2019 Honda Pilot. I give this app a 5-Star rating.

Works great since updating. Could use a few more PID’s. But otherwise works great since updating.

I’ve been using EngineLink since it was first released. I’ve used it on 20+ vehicles... from Lexus, Acura, Toyota, Honda, Pontiac, Ford... etc. And I’ve used it with every iPhone starting with the iPhone 3 and now the 11 Plus Pro. It’s never failed me except for a couple weeks when the iPhone 6 was first released. I use it on vehicles that are generally 5-15 years old with high miles. Will it read everything? No. It didn’t help me with a wheel speed sensor on a 4Runner. And I’m sure there are other sensors it won’t read. *But... what it is great at is building customized dashboards to read and record several sensors at once in order to diagnose and monitor engine performance. I have 4 custom dashboards each with 7-10 dials of instrumentation. I screen record then watch it later to get the info I need. And also to see the difference after I install a new go fast part or just something as simple as a new air filter or even the difference in engine load with a roof mounted bike rack vs. no rack. Want to see the vehicles MAF/MAP/AMF intake volume and pressure, engine RPM, atmosphere Barometric pressure, atmosphere ambient air temperature , 02 sensor voltage, fuel pressure, engine load, and engine torque all at the same time? This app does it... and many many many more combinations of what ever you want to monitor. Want to know if your catalytic converters are clogged or if it’s just a bad O2 sensor? This app will give you the info you need to diagnose and determine the answer. And possibly save you $1000-$2000 on the catalytic converters Mr. Mechanic says you need. Amongst other things ... I’ve personally and easily diagnosed (and saved myself a ton of cash) bad O2 sensors, good (not bad) catalytic converters, fuel pumps, dirty MAP/MAF/AMF, loose intake hoses to a turbo and tightened a bolt instead of buying a new turbo, dirty EGR valves, bad coil packs, bad or loose plug wires, bad plugs, bad evap canisters.... etc etc etc. If it’s connected to your engine this will tell you what you need to know. The best part about this app is the elm Obd2 port WiFi units are cheeeeaaaaap. And this app is cheap. Do not believe the bad reviews about the app not working anymore because it’s simply not true. I bet their Elm WiFi unit was the problem. They probably dumped a soda on it or something else that ruined it. Anyway... I want to give a huge thanks to the creators of this oldie but goodie app. I used it today to monitor everything on my Lexus after a few new goodies were installed this weekend. Worked like a charm !

I bought this app specially to monitor my vans transmission temp and it does not work. There is a custom PID which I tried using but still no temp display.

Bought both the adapter and app from these people. The adapter works with other apps, this app won’t read codes. Will connect, but that’s kind of useless without the codes

Won’t connect to my 2015 Nissan Sentra, but will connect to my Chevy and Ford only not working with Nissan
