Torque app with oil temp
 

I'm having a custom turbo kit made for my car and I have a Nexus 7 set up with the torque app that I will be mounting in my dash. I want to get the most reliable and fastest connection possible to the Nexus 7 and I want the app to be able to tell me the oil temp amongst other things.

What is the best obd2 link, cable or adaptor to use to achieve what I am looking for?

Thanks in advance guys!
