Think I have a temp fix for the istick 40 underfiring in temp mode, unlock resistance, remove coil while device is on, screw back on and press fire, when prompted say it's a new coil, relock resistance and boom I'm down from 500f to 360f and a far better vape, coil resistance now reads 0.17 from 0.13.
edit: And now an equally annoying bug, once I've 'locked' the coil in at its 'new' reading, it eventually decides it wants to revert back to its original 0.13, WTF ELeaf!! The whole point of locking the coil resistance, is that it doesn't change isn't it??
That's the same as I do on my dna40, Fire the coil for a second, remove the atty, fire a few times so it knows that there's no coil and then screw it back on to get a higher resistances. Like said before, this allows me to get higher temps at lower recorded temperatures, a better vape but it is a false reading.
I think half the problem is actually us, the user... We are so used to a warmer, cloudy vape.. I've not used TC in over three weeks and can't remember the last time I got a dry hit.
