Nickel200 wire is used to make TC coils. Some mods have a mode for Titanium wire. I don't believe the Ti firmware update for the SW is published yet. Ni200 is much less resistive than Kanthal, so your coils are going to be down by the .3-.2 range at best. Not to worry, that's what the mod's looking for. Do not dry-fire Ni200 coils; when hot nickel can give off harsh fumes. These coils are wound as spaced coils, not contact coils like most of us build. Even spacing can be achieved by winding them on a machine screw of appropriate diameter. Ni200 wire can be found online, just search for it. It is sometimes called "non-resistance wire." If you build Claptons or twisted or other fancy coils, I am told you can use Ni for the main wire and Kanthal for the bulk. I don't know that's true, I have only heard it. Ni is very soft and can be hard to work. "Tempered" nickel wire is also available; it's a bit stiffer and easier to coil.

how many wraps is .3 ohms? cause steam engine is telling me 24 gauge ni200 dual coil is like 100 wraps is that right?

Dual coils are really finicky with nickel, not to mention the resistance range is already super low without going dual. I'd stick to single coils, at least at first, and if you're going dual you'll probably want a thinner gauge wire just to keep the resistance up. I use 28ga for single coils, 9-12 wraps with a 2.5 or 3mm diameter (depending on what will fit in the particular atomizer I'm using) and they usually come in between 0.1-0.2 ohms

Here's a sub-forum dedicated to TC. A lot of good info in there: Temperature Control | E-Cigarette Forum
