well darn.. just as i navigated thru the TC menu and set it all up i realized, the crown 3, .4 ohm coils are kanthal.
not the .24 or .15's.. just the .4's!!
so why can't kanthal be used in tc?
i threw the box away and just happened to come across a post about them being kanthal.
can the NRG .15 coils be used in TC?
just want to update for correct info. the crown 3 coils are ss316, the ones that were sold on fasttech were kanthal.
So i'm back to trying TC! And now that i know the NRG coils are kanthal, that explains why my vape was too hot even at 370 watts. I have it set right now at 400 and it's not hot.
