Poll: Power mode Or Temperature control mode?

Yes, that's exactly my complaint with the Joyetech firmware. First it overshoots, cooking the coil, then it throttles back so much you get a totally insipid vape....

 

The pre-heat is adjusted too high, it ramps up very fast, then goes into temperature protection mode which then cuts off the vape. It's in particular unreliable below 0.3 ohm. The correct behaviour would be maintaining the temp at 1 - 3 W power.

I set it at the similar wattage as I'd vape it under power mode. Therefore I use TC only to cut of those peaks and help to make the vape even. I use above 0.4 ohm only. Then the eVic Mini works like a charm for me.

 

This is the same technique I use with the eVic. With an SS316/304 coil, I first go to wattage mode and find the right wattage (usually something that corresponds to a voltage between about 3.2 and 3.9 volts). Once I have the right wattage dialed in, then I switch to TC mode.

thankfully with the DNA200 it's much simpler. although I do find I have to dial in a much higher wattage on the DNA200 than on the eVic, otherwise the DNA doesn't quite hit the temperature limit. The device monitor is very useful for showing this. On the eVic, with a 0.7 ohm coil, I'm at about 18 watts to get a decent vape in SS316 mode. On the DNA200, with a 0.7 ohm SS316 coil I use anywhere between 23 - 28 watts. Although to be honest, the upper limit doesn't seem to matter - I could set it at 50 watts and it would function the same. Just cannot set it too low.

With the eVic, set it too high and you get a cooked coil...
