Ok, so i just finished up my first dna 20 mod 2 days ago, all is well. No issues at all. works great. So i started on my next one because i got a 2nd DNA20 board/chip from a trade. I wired this one up same way, same buttons. turns on fine. wattage adjust fine. fires fine but as soon as i screw a atomizer or carto etc. the wattage just goes down all the way to 7w as if im holding the down button. Nothing touching the on board buttons, tried disconecting the down button, still does it. but if I unscrew atty it stop lowering wattage. It does not have any error messages on screen, if I hold up button it just stays at that number but if i unscrew atty the numbers go up/screw back on atty numbers go down. If i fire it when they are going down it stays at that wattage until I let go of fire button and it does vape. Im am lost. has any one had this issue?? any solutions???
