Yes I used the numbers for both SS and Titanium that SthrnMixer provided and entered them manually.Works like a charm!
My somewhat opposite experience is to try and load curves for all 8 profiles and when you try to save an 8th one you get an out of memory error. I followed some advice from a help thread with the DNA guys and still could not save that last curve. Maybe I should do it manually.
Why so many profiles? You need one for Ni, Ti and one for SS - isnāt that it? Or do you use your profiles for other things as well?
This is from the Evolv site.
āEvolv recommends setting up one profile for each atomizer that you regularly use with the DNA 200. It is much faster to switch profiles than it is to set up the settings for the atomizer again.ā
Not sure I get the why either though.
Ah sir, have you used a DNA 200? I assume that you sleep on pillows of them. I have a profile for a given tank that I refresh for every build in that tank. Have you read I have a long and stressful commute? I swear to God I could kinda see me some jihad for people that slow down to look at a vehicle stopped on the side of the road. Iāve got rapid fire tank switching, batteries dropping like clips out an uzi. I needs me some vape.
What I donāt understand is what extra memory it takes to store a curve of a different shape. I read that you could go in the about screen and click on the logo 7 times or something it would unlock a curve editing feature whereby you could reduce the unimportant points in the curve that are far outside the operating limits for vaping. So now I have an additional question of why in the hell are those points are in an apparatus to be used for vaping? I suppose the answer to the second question could obviate the first.
It stores you resistance, preheat setting,temperature, and fire power setting.
A third question is why we still have the power setting in TC mode. It makes no sense and every one of my mods does it.
Iām going to take a stab at answering your question.
First off, I suppose it could be done where your mod could just have temp set and thatās it. Mod fires to that maximum temp and then meters the power to maintain it. But due to all the various type of builds and wire gauges, the programming would be incredible.
I think the power setting being left up to the user is smart because with just a few clicks the user can tailor the vape for the wire/build being used. For example, I can run two dual titanium builds. Letās say one is the Goblin Mini where Iām running dual 26ga and the other is the TFV4 with dual 22ga. It will take more power to bring the 22ga wire up to temperature and maintain that than the 26ga build. However, the coefficients are the same. So while temperature control function works the same, the power needed to reach temperature is very different. I can run 80 watts on the dual 22ga, but may only need 40-45 on the 26ga. At least thatās how I understand it.
Also this is where the xtra profile spots can be used effectively. If you have 4-5 different builds with various wire gauges used and single/dual configurations you can set up different profiles to match your vape style with them. So if you like a preheat of 75w and running it at 450F / 45w you can save that. Then maybe you have another you want 110w preheat and running 520F and 65w you can set that. Switch on the fly.

I have no problem with the last paragraph, The first part though, if you are controlling temperature just start doing that when I press the button. The amount of power used to get there is different, but itās not controlling power itās controlling temperature and itās doing it by measuring temperature. Its exactly what you say in your first paragraph, except it is actually quite easy and no programming at all is required. The only time the power button has an effect is if you want the mod to fire the coil to a lower temperature than your control value. Then you turn the power low enough to where it cannot get to 400 degrees for instance. Thats why it makes no sense to me. It especially makes no sense on the DNA 200 with the pre-heat pulses.
Iām going to follow a link @Big_Benny_MI sent that looks like a slick tutorial to see if they say the reason. I mean, I have a degree in electrical engineering and I dont understand it. . .which is not necessarily saying too much cause for all we know Iām an idiot.

I hear you. But itās not controlling temperature really with the way itās set up. Itās limiting it. So if you use the example of the dual 22ga Ti build, set it to 500 deg, but watts to 35, it will never reach 500 deg because 35 watts is not enough to get there. TC is not a thermostat, itās a limit. What I meant by the programming is where you may need 80 watts or so to get the 22ga build up to temp, on something smaller such as dual 28ga, it would require substantially less power. So in order to have presets for all the conceivable wire types and builds there would need to be a ton more programmed onto the board.
Rather than have some generic whereby the preheat is static and the power adjusts by reading resistance fluctuations more rapidly so as to adjust the power quickly to meet the user-input temp, the user is able to set power which best suits the build. Again I could be wrong about some of this but itās what Iāve come to understand from the use of the product.

Actually I have to disagree with this point. So if Iām running my dual 22ga build and Iām running 500F. I suddenly feel itās too hot. I donāt turn down power, I turn down temp. Again the temp control functions as a temp limit. I actually do this all the time and rarely will I turn down power when wanting cooler vape, just turn down temp. But lowering wattage will indeed do the same thing.
LOL - I keep editing this reply because I will think of something else. Ok, let me clarify my thinking just a bit too. When I say I rarely adjust watts, thatās assuming Iām on the same build or real close to it. I have my Aromamizer with dual 6.5 wraps Ti, my Velocity with 7.5. If I switch between these two I probably wonāt mess with watts much. But if I go from the 22ga build to the 26 ga build, I will definitely lower the watts. Sure I could simply lower the temp, but I donāt want to hit those small coils with 80 watts even with a great working temp control limiting me to 450F or so. It just seems risky to flash that small coil with such a sudden burst of power. Ok, Iām getting funky tired. Iāll check for your reply tomorrow my friend. Good night.

Ramble of the year, but check it out. Ha ha, I just read all your edits for the first time. Good stuff. I think all this explains everything pretty well:
I think you misunderstand my meaning by āitās not controlling power.ā First, I am not sure what you do for a living, but Iāve spent half a decade designing temperature control circuits and my stuff is real damned good brother. Thatās all Iām saying.
So, hear this or dont, I do not mean to be an ass, I mean to propose an explanation which you can adopt or reject based on your own judgement and with no consequences.
I hate to start this way, but it gets better quick, ok? The first concept you need to understand is the perfect control system. A perfect system for controlling a parameter would exert its maximum effort in infinitely many dimensions to set the desired parameter. In other words it would produce the desired parameter at all costs. I think that makes sense, its getting pretty late around beer. OK, so the mod isnāt perfect, but we want it to control temperature to a desired value and the only dimension it can alter is the power into the coil. That means if we are controlling temperature to a desired value, then the controller circuit will choose any power necessary to achieve the desired temperature. It will control to the desired temperature at all costs, that it can afford (which is to say that there cannot be some alternate limit on power). Mathematically speaking this makes power a dependent variable because the power required to get to the desired temperature is dependent on what the desired temperature actually is. So that is the perfect mod temperature control system with the variable power and what not, ya? Thatās TC mode which equals variable power.
Please dont anyone say this is one of those situations that is not so simple as math or something. Iām not saying that any of you would say that, I am just paving over the possibility. Now, pulling that back away from the mathematical simplicity, that power is dependent on what temperature I desire, we just said that. Itās right about now you realize that the power setting on the screen in your hand doesnāt mean a damned thing other than the possibility that you might underdrive the system such that it never reaches your temperature setting and you are setting some limit, on another parameter than just temperature,but on the power (for some reason, I again, do not understand), if you chose to do so.
Again, I say these things with the utmost respect and sincerity and in no way do I mean to convey any condescension. My words often have a certain flair but,I mean them to reflect nothing on you or your opinion as they are simply a statement of mathematical fact. Buy it or dont. People can do math incorrectly and all of my math is words anyway.
You know I love my DNA 200 device(s), they are very nice and pretty impressive from an engineering standpoint. So I have a great deal of respect for the product, and. . .
I am now getting to understand the power button function having just ripped on it. See we cant just account for the power going into the coil in order to understand the conundrum of two settings, we have to think of the power going out as well. In perfect isolation, say a coil in the vacuum of space, the power we put in would continue to increase in temperature as long as we held the button. . .itās like filling a balloon, the power cant go anywhere else but to heat the coil. It has no other possible optionsā¦ BUT, if we now say well, āhere is a sloppy wick whatās gonna put juice on you, coil!ā first of all we will be evaporating a liquid, which occurs at a single temperature called the boiling point and we will be doing it at a variable rate, depending on how much I suck (you too buddy), While we cannot know how the temperature of the coil is related to power (damned dependent variable bastard is waggling all over the place to control the temp!) applied while in TC mode while evaporating off a cloud at the rate we breathe, we can say: if you boil this amount of fluid it will take this amount of energy (thatās specific to the material) and energy is just a given power for a given time. So it all comes down to just how YOU suck (ME too) in order to remove that boiled fluid so that power can adjust to maintain a constant temperature.
Are you vaping a TC device right now? I seriously am just now seeing this, I feel pretty stupid. If you are vaping a TC device do some fun experiments with me (eXcubes do not apply, you suck), make sure you like your settings and your happy and in TC mode. Push the fire button and take in a long but shallow lung hit and breathe it out as normal. Note the size of the ācloudā. OK, same settings and temperature, no changes, push the fire button and take a big olā āI get the first hit off the jointā kinda mega inhale for the same length of time as the shallow breathe. Note the size of the CLOUD. Way bigger, right? Yup, but the fact that the temperature was constant means that material had to be boiled (which occurs at another, different but constant temperature). The AMOUNT of material that has to be boiled depends on the temperature difference between the setpoint and boiling point of the fluid multiplied by a material constant. By example, and itās kinda weird to think this way, If we are controlling a coil temperature at right around the boiling point of the juice, then the amount of vapor produced has to be large to carry away any power because the multiplicative temperature difference is small. If the difference between the boiling point and the setpoint were big a smaller cloud would result. The loss of mass due to boiling represents an energy which was released over a period of time, and that is power. So vapor = power. Clouds is Watts. I guess itās shorter than āHow big you want dat cloud?ā
OK so the other thing you can do is switch the two variables in that last example. So in this opposite case, which granted is also a little hard to imagine: Suppose we want to drag a cloud (mass) out of the mod again by varying the power to control temperature to a desired value. That is the only rule, we are always controlling power to hold a desired temperature. So set your mod to 20W same temperature we have been using,and pull the biggest cloud you can. . .Small right? OK, same temperature as always turn your power up to 75W. Same thing, drag the biggest cloud you can and exhale all that mass which still represents an amount of time over which a liquid was boiled at itās characteristic boiling temperature so that cloud of mass corresponds to how high you set the power. You just showed that in two puffs. Said otherwise, clouds are watts or vapor is power. Which is the same case as before we swapped the variables but kept the āone ruleā in the experiment above. I think that should be proof enough. But. . .I ramble and thus:
As we just proved backwards and forwards: clouds is (the) power (setting), How big the cloud is is determined by the power setting. Or, if I am drawing all unevenly or stop all of a sudden the temperature setting will limit the amount of power into the coil such that a smaller cloud will be produced. It does this so well that if I take my mouth away from the drip tip and pull the trigger no cloud will be produced. And you guys with TC mods have all just done my little experiments. So you totally get it, ya?
āBut hey, TRW, you just said, and I quote āā¦other than the possibility that you might underdrive the system such that it never reaches your temperature setting and you are setting some limit, on another parameter than just temperature,but on the power (for some reason, I again, do not understand), if you chose to do so.ā.ā Yes I did say just that, but now I understand the reason one would choose to do so, to have a seperate power setting. Itās because one wants us some clouds not just a warm coil! Provided I suck (and you), the cloud size will depend on the power setting. We had to account for the power leaving the system in the form of the mass of our clouds to understand why we set temperature AND power, even though power is a dependent variable! In truth, Itās only able to control your temperature and be dependent if you suck (and me too) at a rate that takes a cloud representing the power setting during the time we had the button pressed.
First one to read this all the way gets a cookie (Biscuit (INW)). My head was kinda spinning but that was pretty fun. I figured it out in the order I typed it. Iām glad the solution circles back around to my original complaint. Probably says this on the second page of the manual, huh?

In a perfect system, perhaps. But I think perfection also depends on the application.Something industrial, sure, go for it. Something Iām putting up to my faceā¦not so much.
As I stated before, the knowledge I have gained is from use of the device. And where you could read and understand Evolvās technical data, I may not grasp it. But what I do understand is that both the power and temperature set by the user are dependent variables. Because just like the power setting, the temperature setting doesnāt mean a thing if the power needed to reach that temperature is not set high enough by the user. If I understand all youāre saying, that is where imperfection lies. But again, I like this because it acts (in my mind anyway) as a sort of fail-safe, so that if TC function fails at least I wonāt go over āxā watts and catch my throat on fire.
So, does this mean then that even though I find my DNA200 boxes to be far superior in performance to my other TC mods that I should change their label to TL (Temperature Limiting)? Maybe. Maybe Evolv should do this too. But only inasmuch as you can set the two variables far enough apart that the temperature is never reached. Put this baby to 300F and 50w, I think temp control is an accurate description. Yes?
Anyway, I loved your post. If we lived close i would want to get a beer together and pick your brains.

Well, here we can assume everything is perfect and put it to your face, yhere is no contradiction. And yes, you understand it correctly. I am now understanding what you mean by temp limiting, but it is also power limiting too. Both settings are limits, which one is doing the limiting depends on how big a drag you take. So yes, we were both right from the beginning. I just wasnāt getting the whole picture theoretically, but you knew it intuitively. This dual limiting drag dependent behaviour, I think, most people āknowā just from using the device.
I just never took the time to really understand it. Because a true ātemperature controlā cannot have a single power setting. We basically set harshness and cloud size limits set by temp and power respectively.
Did you do my experiments? Itās kinda fun I think

No, I had already figured these things out beforehand. Although the results are the same, my notion for why more vapor is produced when you put the suction to it is slightly different. It has less to do with the amount of atomized liquid youāre pulling off with increased suction and more to do with the volume of air hitting the coil and cooling it. Probably some truth to both concepts, and Iām happy chalking that up to semantics. Fun? Yeah, but whatās more fun is having a good conversation about it. I really appreciate hearing from your technical and educated side of things.
Well, you didnāt need my explanation, haha. Your comments on increased air hitting the coil are spot onā¦the thing that moves that are is you sucking (me too). Haha. Good times, I agree.
I suck! Man Iāve heard that a few times. I do, after all, have step kids who are now young adults. I discovered I suck when the oldest was about 13 - downhill all the way till they got in their 20s 
Funny how adulthood and the challenges of life make kids appreciate a hard-nosed parent.
