I wanted a ultragauge but decided to purchase the torque app and the ob2 bluetoothed reader,I am very impressed for under 25 dollars,the only item I cant seem to read is air fuel ratio or could I use O2 voltage for that.

 

My understanding.. is it takes a wideband sensor for actual AFR readings.. otherwise you will only be getting "commanded" settings. And not real sure how to get Torque to that stage.. played around with some of the forum's LAMDA formula's but never could get anything to read, which I'm sure was lack of proper PID address.
