Nope; just the kind of metal. Everything else can be calculated from the internal electronics of the mod.
EDIT: Everything else important. The gauge, and length of the wire is irrelevant.
Yep, just the type of metal. The mod has the curves built in, you just have to tell it what metal, so it knows which curve to use. Some TC mods will also let you enter new curves for metals not in their factory program, or to adjust an existing curve for personal preferences.
Makes sense - thanks for all of the replies. I am toying with the idea of trying one. I am very well set with what I have, but TC interests me - at least a little...
Likewise! Many of my mods are TC capable, but I've not gone there yet
