Gonna have to play with it a bit.....  THX again dwcraig1....


Usually i put at 600F, as temp is not that important for this matter. (at least i think that way, but always learning)

I'm just pondering the graph results as opposed to the preheat being shown in the graph.....  no doubt the preheat has to raise the coil temp during preheat.  Gonna play with temp set above and below 482F and see how it effects the graph results.  But that's for tomorrow as it's late here.....

This might be a silly question, but why do this? Is it to make sure the coil is quickly at a nice temperature to vape? Personally I never had much issue with that, just wondering. Currently breaking my head over my SS316L TC settings.

It depends on he amount of metal you have to heat. Claptons, Alien coils and so on, need a lot of watts to "wake up", but then it can be too much watts to maintain the heat you desire.
Less watts will get you there, but then the ramp up time will be more.
With preheat, you get more watts to start, and less to maintain, achieving a better vape experience.

With SS316L you can have preheat, but on most of the times you will not need preheat on SS, as it ramp up pretty quick and then DNA200 will have an hard time to control the temperature due to SS316L low tcr.

So my Kanthal with preheat didn't seem to work with SP3 so I went back to "recommended" and it worked. But then I flashed it back to SP3 and preheat with Kanthal works. This is with a DNA200.

It is awesome! Running it at 85 watts with a 110 preheat on a DNA200.  Heats up my dual fused claptons nice. Better flavor. Nice job.

I also cannot get it to work on my therion. I'm also having issues with my tc on other actual tc coils.

Anyone tried this with nicrome 80? Most of my non-TC builds are nichrome, which has an ever so slightly larger TFR than kanthal. Wondering what I should change the coefficients by to make it work.

I answered my own question. It works! I just used the same method of adding .1 to each point after 382F.

Device monitor results are below. And my .csv file is attached if anyone is interested.
