Hey man, I'm glad you posted this. I just got the cubis and was excited to try out TC with stainless steel. I made a separate profile for the ss316 coilheads that the cubis comes with. It says right on the coilhead "ss 316". I uploaded the correct .csv file from steamengine to my DNA. Had the watts set to 200 and temp at 420 (how I like it on nickel) and it spit out this piddly puff of vapor and didn't do much after that. It simply would not hear up enough to get any vapor. I messed with the temp and watts, still nothing. I don't know if it's the .csv file or of joy tech really doesn't use 316Ss. When I turned the DNA over to nickel mode, it BURNED my damn coil and cotton. This spoiled my experience with SS wire AND joytech's god damn coils. If any one has anything that could help, please let me know.
