Evolv's announcement of the use of non-resistance Ni200 wire got me thinking about the whole temperature control thing.
Their design restricts your use to Ni200 (nickle write). But could temperature control with downregulation achieve the same thing if there were a reference table for wire temperatures?
If the device knows the resistance of the wire and also knows the gauge of the wire (you would have to input that as a variable), what if a reference table (through research) was done to determine the temperature kanthal heats to, to determine the appropriate wattage to achieve the target temperature? The mod would have to know the gauge, but it can read the resistance so if it internally knew gauge ratio to resistance and compared that against a known temperature table, and the mod downregulated to the wattage output in the table, could you achieve temperature control that way? That would give you the ability to temperature regulate without reading the coil resistance.
Please poke holes in this, there are greater minds on this board than mine.

P.S. Here is the mathematical basis on which I am suggesting the idea:
