To update this, I bought the X Cube II the other day (was going to anyways haha) and can fully confirm now that yes, you can manually adjust the initial ohm reading for TC purposes. The only option you can't change on the mod itself is the temperature coefficient, that can only be done on the app. It is default 0.006 on the latest firmware (1.08), but you can change it to 0.0038 to support Ti.
