Just recieved by cheap (<$15) bluetooth ODBII reader and bought the Torque Pro app (android).

At a quick glance it looks like it will be helpful for checking my new tune is not pushing anything out of the desired ranges.

I've not given it a full blat, but noticed the Boost reading is a negative (manifold value), not the atmostpheric pressure I'm used to seeing on VagCom (1000mb at idle). Would love to get it showing req and actual boost values, intake air volumes, temps (does that well already) and some other bits.

Before i dig, thought I'd ask on here as I know there are a few tinkerers who have tried it (coudn't see a thread on it)

Pretty cool app, good for the cheap spend.
