I just bought the iKuun i80 and I'm having a problem. #1 it came with a pre-installed . 3ohm coil the device is reading it at . 23ohms & 2.78 volts ,is that normal? im only using it between 30-33 watts my 2nd question is when I fire my mod I'm getting alot of spit back ! How can I fix this issue ? It's anew coil, & I primed it before using & let it sit for almost 20 mins. Please help
