Digging this one out of a cold grave...
I just loaded up Torque Pro on my phone since I don't like having my SCT X4 plugged in all the time, and because the app has more pretty customization options.
I was really hoping to be able to display the OAR, but alas, I couldn't find that PID anywhere in the app. Naturally, google lead me here, but I can't seem to get it to work. When I put the equation in, it says "empty string." It's typed correctly with no spaces, but it just wont take it. Any idea what gives?
