It's kinda pricy compared with other modules but it seems to be on the faster end of data rates over BT.

If you have a droid use this, save yourself the $70. I've had mine for 2 years and no problems yet.

torque app
 

have used this app for the last two years also. great app.great scan tool for codes etc.

Nismo I use the OBD MX and torque pro in my twin turbo nismo for real time monitoring. Very responsive as far as data transfer speeds the rpm gauge is almost instantaneously on point that's what I was most impressed with. I've had to use the unit on a couple of my buddies cars as well to find trouble codes with the torque app. Diagnosis is quick easy and detailed. Can't wait to get it mounted in the car once the build is done

I just wish I could find one that has a composite video out with selectable display range so that I could send it 840 x 480 to my head unit display. How cool would that be? Instead of juggling a PC/lappy, or an iPad, or squinting at a phone screen, you could glance right at the head unit aux input and see it all without any fuss or bother.
