No Gimmicks , But a practical Basic Scantool If you just want to read and reset fault codes this is the app for U. It connects real fast and tells U the Obd2 fault codes. But there is not much on diagnostics. But then the app is free and you do not even have to pay for an expansive adapter.
Good app. Thanks a lot for support! Connected well to my wifi iobd on andriod. Read all errors I wanted to see. I recommend to move Settings button to left floating menu. My respect to developer.
1st app that worked with cheapo 327 Bluetooth! I tried 10 or more apps and got *nowhere* with my 2005 Cary. With 'Piston' I am able to read everything *and* was able to reset my 'Check Engine' light! Yay!!
Piston connects every time. The interface does exactly what I want it to do. It will tell me things about my car that I never thought to ask. Consistently reliable. Easy to use.
Fantastic APP!! If you dont get a VIN or some other data, please understand that not all cars provide everything such as VIN. especially on EU or UK vehicles. This is not the apps fault! Keep up the good work dev!
Almost perfect Clean ui and works well. Just need the ability to reorder and customize the live info screen, and some more monitored variables (esp. Fuel econ). I prefer it to torque. The ability to plot selected items over time would be great.
- Improvements for some adapters with the ELM chip in version 2.1.
