So how have you used Torque thus far
Honestly, I haven't been very impressed. I bought it to check codes, and when I do, I get a blank screen. This may mean that I have no codes, or that it isn't working. The Torque web site isn't helpful at all in answering questions, and the developer admits that he is a great coder but can't write documentation. So if you want to know something, you have to ask in the forums and take pot luck.
Edit: One of the recent versions fixed the problem of no DTC messages, or it fixed whatever problem was preventing messages from appearing. I'm now getting a message to the effect of "No codes stored" for all three vehicles.
The developer makes very frequent changes to the program, but as near as I can tell has stopped updating the changelog.
Lots of people love the gauges. I used the temp gauge to cross-check my vehicle's temp gauge, but I find the rest of them pretty much duplicate what I have in the vehicle (yes, the vehicle does have a boost gauge).

Which Bluetooth adapter have you purchased?
The Elm 327 blue and orange one. It seems to work fine, but it comes with no real instructions and the instructions on the Torque developer's web site on how to work with it are flat out wrong. If you get that adapter and want my version of what the Torque developer provided, just ask (I offered them to the developer, who never replied).
