I've done a couple of hour+ freeway drives over the last few days, and the TCC controller is working consistently with no glitches.

I'm considering moving the vacuum sensor to manifold vacuum instead of the timed vacuum port on the carb because it is slightly distracting to have the TCC unlock and then re-lock every time I coast momentarily due to traffic. I'm not sure there would be a downside to this change. I was using timed vacuum for my old vacuum switch & delay relay setup to unlock when coasting down to a stop. That's no longer necessary because the Arduino will unlock under 45mph.
