Good Morning
@nodor, I can feel your pain there. The modes are actually really nice to work with but as stated you do need to push the button to get them to change. At least from what I have found. Regarding resistances, I swap my three different tanks on my mod all the time. Mine has never asked about new coil like I have seen the DNA board do. One think I noticed and by reading the manual is if you push both up and down buttons (something you dont have) the mod will measure and set the resistance. I only have one tank with nickle in it now but I have noticed that by simply pressing the fire button, the display reads the resistance correctly as well without having to push both up and down buttons. I was using a kanger at .15 ohm, then swapped to my Atlantis (.5 coil) and then again my Starre tank at .25 coil. each time i put the new tank on and pressed the fire button the mod displayed the correct resistance. Now mind you, only the Kanger was Nickle and the others I put back into Power mode so I am not sure if that had any effect but thought I would give you my experience with it. Sucks that it burnt up your wick. You may have to actually get the buttons in to take full advantage of all SX features
