What do you think about temperature control devices?

Only time I have a similar issue is with just one of my mods....it has a spring loaded center pin that has a weak spring and when the pins get just a bit dirty the issue shows up... when the issue pops up I just clean the center pins and issue is gone...other mods I have with spring loaded center pins don't act that way.... go figure... gonna change out the 510 some day...
Guess I need to be more religious with cleaning my center pins - both of my DNA 40 builds use varitube 510's
I just wish I knew what was the issue with certain builds that causes them to read weird - I feel like I am doing them the same, but obviously not.
Preheat is one of the best features made possible by tc, IMO, so I'll just say I strongly disagree.
Still not sure what you mean by "dump" power though, preheat lasts 1 second max no matter what happens.
I had one DNA40 unit that out of the blue dumped 40W into a build that I run at 10W. It was a hybrid, hard-wired for minimum voltage drop, the atty cannot be removed by simply unscrewing it. It happened twice over maybe a 6 week period that the mod was in use, so, very rare. My point is that I have experienced this happening and no use blaming it on user error/build error/poorly built mod/dirty 510.
So correct me if I'm wrong but didn't Evolve state there's a superheated layer of vapor above the coil? If so has the temps generated been disclosed? I'm wondering how much benefit is there to coil temp control when a superheated boundry layer exists in current atty's.
Brandon from Evolv spoke about high temperatures from mechs with low oHm coils producing a superheated layer of vaper that forms next to the coil which prevents it from being cooled starting at 41:11 in his Vapour Trails/Haze Hour's Dec. 4 interview. With temperature protection enabled it seems unlikely one would get much of a superheated layer, if any. However, if a superheated layer did form preventing cooling of the coil the DNA40 chip will throttle back power to keep the coil at the set temperature.
The device putting 40 watts into a setup that is usually run at 9 to 10 watts long enough to give you a dry hit is what I consider dumping. In all reality, I don't know if it's just the preheat function, or if it continues after the 1 second that the preheat is supposed to last - I'm not measuring the interval with a stop watch when I get a dry hit, and my sense of time probably is not that accurate when I'm coughing
I also let off the fire button when it happens. Next time tho, I will continue to hold the fire button (just not inhale) and see if the temp limit does kick in eventually. I have my limit set to 400F.Well, at least I know I'm not the only one.

Sorry, shens. For one thing "builds run at 10w" can take 40w preheat, from direct firsthand experience. The only time I have ever experienced this, over many mods, since literally before day 1 of the DNA40's release, is when I turned OFF temp control while having the wattage at 40 (I leave it at 40 with complete impunity when I run TC, never ever had a problem). The only way this happens when TC on is if you have coil connectivity problems and TC shuts off.
The whole concept of a "setup usually run at 9 to 10 watts" goes out the window with TC. Talking about setups that way basically shows a lack of understanding of TC and/or lack of significant thoughtful experience with it. Temperature and wattage are not directly related and operate on a continuum throughout the use of a device.
Given that the coil is the part that heats up and makes the vapor in the first place, I'm wondering how this can even be a question.

And I'm telling you from first hand experience, that the build when working correctly, reaches its temp limit at about 10 watts - that is what I'm referring to. It is not BS. It basically heats at 40 watts as if TC is turned off when it malfunctions. If you are telling me you have never had a build that wasn't perfect, I am seriously going to doubt that.
I am perfectly content with TC when it works - the point I am trying to make is that when it doesn't, it is very unpleasant. And I think that a change in the way it preheats or tries to switch between TC and non TC (if that is what is causing the symptoms that show up) should be looked at. Maybe I'm using the wrong terminology for exactly what the chip is doing when the chip screws up. Maybe it's not the preheat function - I do know it's just pumping out enough power (for whatever reason) to instantly give a dry hit. Why should it do that when I have the wattage set at 10?
The reason I am upset is that I have had this happen on tanks that vaped nice, took them off to change flavors, and then later put them back on (usually after 10 minutes, sometimes longer), and had the chip fire it at some ridiculous power giving a dry hit. I have also had it happen on a tank that worked fine the day before, and the first time I fired it the next day, it went full throttle. And I don't know what is the difference between the builds/tanks is that causing the issue - if I did, I would amend my build technique, solve my problem, and post it up to let others know what to avoid. However, I believe that a change in the programming would eliminate the dry hit - you might get a weak vape or it would shift out of TC mode, letting you know your build has an issue, but at least you wouldn't get the evil consequences.
ETA - Maybe you think I am trying to bash evolve and that's why you threw out the "shens" comment. If so, you are mistaken. I have two genuine DNA40 devices - they are my daily vaping devices. I am thinking about building up a third one. I am merely discussing the issue I am having and that maybe they could look at the programming so that this problem can be eliminated. I seriously think TC is going to be the way everything goes in the future, but they had better make sure it truly is plug and play for the masses.

Because the coil is in a different temperature region than the superheated vapor. I'm sure Evolve had questions that they wanted answers to regarding that since they discussed it. It would make an interesting portion of a White Paper.

Well the coil creates the region so it has to be directly relevant.
I have had many bad builds but they hit temperature early, not later. In no cases have I had an unexpected application of more power to the degree you describe.
If you set your board at 10w even if temp kicks off it will not go to 40w.
