More than RPM with Torque app + ELM327?
 

So I had the Torque Pro app for android and a cheap ELM327 bluetooth adapter for a while now and it works for reading and clearing fault codes. However, that's about it what I can do with these. When it comes to the sensors I can only read the RPM data. Now someone claimed in another thread that he's able to read for example oxygen sensor voltages (having a 16v engine 2001).

Now I'm wondering what experience do other people have? What can you read?

Depends on the car my civic you can read most basic and a few complex stuff and voltages and air fuel, I used it on a 05 bm 320 and it could read literally everything.
