set it before or after, shouldnt make any difference. I need to sleep but you could try slamming in a single coil, wick it but dont juice it, set temp to 430F or so and fire it. It should start to singe the wick, if not raise the temp a bit and try again. Lets see if the mod is actually working properly with a dry burn test!!Yes that ive done. Ive played with the temp up and down to warm up the vape but there is no change. Does the temp need to be aet before locking the resistance?
The other thing to do is put a kanthal buiold in something and try it on power mode!
I also really recommend starting with a single coil. Duals can cause all sorts of problems if they arent identical!
