Hey, I'm having some problems with my DNA 200 mod and I'm hoping you folks can help out. It seems no matter what I do, I can't get TC mode to work with my SS coils. I started with fused claptons. But since it wasn't working properly, I decided to try just normal parallel coils. But that isn't working either. Here's what's happening: It doesn't recognize the temperature. I used eScribe's Device Monitor to check, and also fired the mod while looking at the built-in display, and on the mod it just shows "---F" and on Device Monitor it just shows "?" on the temperature. I've tried everywhere from 200F to 600F, 20W to 150W, and every permutation/combination of those variables, and it just won't read the temperature. Most of the time it fires at full power, but sometimes it will randomly decide to fire at 0.2W as if it's already hot but it doesn't produce vapor. Oh and I almost forgot to mention, I'm using UD brand 316L SS wire. Currently I've got a 0.1 ohm parallel 24ga dual coil build on it. I've also tried up to a 0.2 ohm build, using Claptons, Fused Claptons, and parallel coils, haven't tried just a normal coil yet. Maybe it's just too much material in the atomizer for it to read? And I'm using TCR I got from Steam Engine for 316L SS. Here's the TCR values: "Temperature (degF)","Electrical Resistivity" -100,0.894808435072142 0,0.9588476571924915 70,1 200,1.0721420643729191 400,1.1702552719200887 600,1.2568175278497145 800,1.335482796892342 If anyone has any advice on how to make this work, I'd really appreciate it, and if there's any info I forgot to provide please let me know and I'll add it. Fortunately I'm using SS so I'm not inhaling nickel or titanium oxides while I figure this out, at least SS is safe in power mode if I can't get this to work, but I've been told the DNA chip is excellent for TC so I'd love to get it figured out.
