I went back and repeated the experiment, making sure to auto tune after switching coils/heads... I couldn’t reproduce my previous results. Both controllers and coils seem to perform within about 20 degrees (F) of each other. So I stand corrected!
Speaking of which, I’ve also given the cap-less SH experience another try by lowering temps and slowing down my draw. Well, I guess I won’t be using a carb cap anymore. Flavor seems to be better with no cap (didn’t expect that) and I can draw as much vapor as I want. Zero draw resistance, abundant vapor. It’s perfect?
You all are awesome. Shine on you crazy diamonds
I'd say temps are lower without the carb cap, but that lack of temp is made up for by slowing your draw speed down.
You could also try going lower, with your slow draw speed and reintroducing the carb cap. You can probably knock a good 50 degrees off the PID that way (depending on starting temp, obviously).
