Doesn’t work
Great app but..
Live data works
But tried it with a 2019 Mercedes and while everything including live data works great
But
When I try to read dtc code , app crashes 😭
Any help?
Thanks
App quit working
Motores
Tried multiple times- unable to connect iPhone, 14 pro
Looks nice
Fails to connect.
Device says failed to connect but
Either it has failed to connect and knows nothing or it knows it is connected but the app just does not work.
Doesn’t support j1850 vpw
Not a bad code reader
Has in app purchase to get dashboard
Old app
Still works with iOS 14.6! … hasn’t been updated in 5 years though …
Was recently getting frequent “Connection Failure” type messages, but discovered that turning OFF Bluetooth, even though I only use WiFi connection to my inexpensive generic ELM327 OBD2 WiFi only device… It Still WORKS! : but for some reason iOS only supports WiFi connectivity on genert ELM327 OBD2 readers.
This free app version does ~90% of what other paid version apps do: though mostly I just need it to pull/wipe Codes, monitor Idle RPMs, test readiness diagnostics, and air/water temps.
Of course using the ‘Dashboard’ on test drives, the Diagnostics and Performance screens, and perusing my custom dashboards also, gives me all the basics (and more) to troubleshoot problems, and monitor the success of my repairs etc.
Thank you to the developer for having made such a nice little free tool that still works correctly with my generic ELM327, even though my late 90’s project cars are technically too old to be on the modern supported databases of most newer paid reader apps!
