I've had a mod box for about two weeks now but I'm having trouble understanding where the settings should be on it like ohms law and temp mode or watt mode, I have a xcube2 160w with a kengar sub tank mini with a 0.5ohm coil in it and I have 70/30 or 100 vg juice right now my box is setup at 28w it's showing 0.55ohms, 4.20v. Any help would be appreciated I just want to understand more about how the actual settings should be not just for this mod but any mod like how would I know where to have it set or within what range,
