The atomizers I want all work best with TC, but because they are so weird they have odd resistance that don't align with any of the base tcr numbers.

Resistance doesn't correlate with tcr values like that.

Do guys know if I would be able to with this mod?

Only if whatever material being used for the heating element is compatible with the TC options on that mod, and the mod does a relatively decent job of guessing the temp of that heating element via resistance polling. TC doesn't measure temps. it guesses them with math, using the changing resistance of the TC wire... No publicly available mod can direct measure heating element temps. So any legitimate vaporizing of dry material you attempt is dependent on that.

Also, remember that any concentrate/shatter atomizer that has metal in the airpath is not really healthy for you. This is why the vaporents treat it like the red-headed stepchild, you know...

Not really looking for mod recommendations but really do want to know more about how tc/tcr work as well as the basics on reflashing mods to different firmwares.

The only true "custom firmwares" available that I know of are on the Joyetech chipset platform. (MyEvic and Arcticfox). Everything else is a font hack.
