i been using Torque app, good app but limited, nice bit of eye candy and can be used as a HUD too.limited to what info is coming out of the obd2 port on your celi.. would have been nice to have oil pressure reading.you can have two blue tooth devices running at the same time if you have a reasonably competent smart moby. i use a Samsung note 2 and it bluetooths to my Kenwood head unit and the obd2 unit at the same time both working simultaneously.only downside is a slight time lag, so when using shift lights, by the time your rev lights hit red and its time to change gear, because of the lag you have already hit the rev limiter...Doh! looks nice though.. Big benefit of useing this app is that its dead easy to read engine fault codes and clear them at a touch. even set up an alarm for when engine throws one up and get notified straight away
I found a fix for the abs light problem but it involves cutting a wire in the obd2 connector
