Mine is a Hcigar dna 200 so its not a Lost Vapes issue quite a few people have or have had the same problem. I also did a SS316L clapton build in a Boreas and Steam Crave Supreme and also Ijoy Tornado nano they all go funky on the DNA but on the Ijoy LUX + Joyetech + Fuchai + Istick 200 they work fine in temp mode. I also sent the DNA back thinking is there a fault but nope no fault found. It works great as a power only device.
