PapaPro,
Well I am glad I helped you even if I am not sure how. One thing I do know is that when first starting with Temperature Control Mods it can be overwhelming and more often than not folks seem to over think the setup. And we won't even get into using coils for the first time in the range of 0.05 to 0.15. The whole thing kind of goes against the grain of everything you/we have become accustom to with Kanthal.
Hehe, I have been using 300f. Sometimes it was warm and then fade off quite fast. So I tried 420. I am using dark juice (I love it) and this is the only one keeping me off the smokes. So I really want my set-up to be consistant. Anyway, at 420f I gunk my coils fast but it tastes so nice. I mean 2ml and they are done. So understanding what was going on was my problem. Until now
So, you explained how using joules to get a warm vape and not temp is the way to go. I did not know this. I think this is the key to understanding how to set-up our M class's. And a good clean coil. What you did was make me see that I needed to find the gunk temp of my juice first, only then do you play with the Js. Sure everyone said temp first and then J. But I did not understand fully that relationship until now. Cheers mate!
One thing I can report back is my Kayfun V4 is working perfect!!! I have six decks and will hammer out builds over the next week to see what is best. But I have my settings working well. I have gone to 320f and 27j and it is perfect on a 0.89 coil. Hard Ni200 defo workes better for me than the soft stuff. I think that is due to better connectivity. Spacing the coils using streaching also works perfect on the hard wire. I really am getting my head around all this and think I am nearly on top of this tech.
Thank you all so much. You honestly have been stars. Take care and have a wonderful vape. London sends some good energy
