Rob did you ever find the place in HPTwhere you can see the lock/unlock of the TC?

You have to log TCC pressure I think, I would need to look in one of my tune to give you the correct PID (shoot me a PM later). It's not as simple as on/off in the A4's. When the pressure is zero it is off, but the tune controls the pressures based on a lot of variables. You can set max and min pressures, but the computer will vary it based on different parameters in the tune.
