Bought my evic vtc a couple of days ago and I'm running into the dreaded anemic vape problems in temp control! Worked flawlessly for 24 hours and then just messed up out of the blue - settings were not changed and were locked, same coil, same everything. I'm using the tron tank and have tried both the ti and nic coils. How can it just stop working properly? Was a solution found?
As i've suggested before, try letting the coil cool to room temperature, unlock resistance, remove battery, put battery in, re lock resistance. It worked for me and others
