I use "always on" to ensure that the IAC will not be moved by vacuum or boost. I can't afford to lose any steps. My IAC does not get hot. The IAC is 15 years old, so I don't really care if I fry it. If I kill the IAC, I will try "moving only". I did the initial tuning in Megatune, but have now switched to TunerStudio. I should probably play with the PID parameters some more, but I moved on to more interesting things.
