what wire works best in temp control with dna 75c?

[leea12345]

Hi there have tried ss316l , so many profiles, coils, settings and all that, sometimes it works, sometimes not , just seem to run into so many issues , just seems a little bit everything needs to be perfect with ss for me . So use it in replay and happy , so am looking for the best tc wire type  for dna75c , Is there a wire type that works more reliable in tc mode , for a noob like me

thank you

Wire that changes the most  resistance when heated work best.

Go here to see TCR values: https://www.steam-engine.org/wirewiz 

Use the drop down menu to change wire type.

Read the value in  "TCR in Vaping Range"

Note Ni200 is 6000, that would be 0.006 for the DNA TCR setting.

Personally my wire of choice is SS430 which has a much greater resistance change than SS316.

thank you as looking at 430, do i just download the csv file as i did for ss316, i get confused about the tcr , do i need to enter this as well? ,if so how , i was under impression i just added the csv file , sorry little confused with all the tcr thing

[dwcraig1]

Yes you can simply use the CSV file but you also can manually add it as indicated here: 

By using the "Action" tab in lower right corner.

you are very kind, thank you for your time, now just got to find some in the uk to buy, does not seem a lot about , also just wish i could have got 316l working ok , spent more time playing about than vaping it , Thank you. 

[dwcraig1]

You might want give NiFe 48 or 52 a try, is lies about in the middle as far as resistance change.

have you tried them,? are they safe to vape i have read some things about certain wires, sorry new to the tc thing

Yes I have, as long as you don't have a nickel allergy you should be fine with it.

[leea12345]

ok thank you , i appreciate your help and advice, will see what i can find in the uk . Thank you

Ich habe im TC-Bereich auch sehr, sehr gute Erfahrungen mit Ti gemacht - allerdings sollte tunlichst darauf geachtet werden, den Draht vorher NICHT auszuglühen...

Ausserdem verwende ich im TC-Bereich eigentlich nur einfache Single-Coils; keine Clapton oder ähnliche Wicklungen, da für diese eigentlich erst realistische Kurven vorliegen müssen, ansonsten sind die Temperaturangaben zu ungenau - da steige ich dann gleich in den Replay-Modus um.

I just got my first DNA mod (75C also) just because of the “best” “most accurate” “reliable” etc etc comments from everyone on forums, Reddit, reviews, damn everywhere. Never once even seen someone say their DNA mod isn’t reliable in TC. Just now decided to come here to join the forum and find a manual or button guide or something. Then I happen to see this first. Gotta be kidding me.

Someone tell me this isn’t common at all please. And 316l is by far the most common ss wire. Wtf is going on here. I can’t believe this is the first thread I see from the undisputed TC champs.

Have you found others to have the same problem you’re experiencing?

Wenn wir hier über Probleme mit TC reden, sollten wir uns nicht nur über das Material der Coil unterhalten, sondern auch über die Wicklung als solche. 

Mit einfachen Drähten gibt es in der Regel Null Probleme! Erst wenn aufwendige Drähte (Clapton, Alien, usw.) verwendet werden, oder auch nur Non-spaced-Coils, kommt es zu Problemen. Dies liegt aber nicht am Chipsatz, sondern an dem Umstand, dass derartige Wicklungen nicht mehr die gleiche Widerstandsänderung aufzeigen, wie der einfache Draht. Und genau für diesen Fall gibt es den Replay-Modus.

The datasheet for the 75C is here: https://downloads.evolvapor.com/dna75color.pdf
The 'fire' button is usually the big one. The 3 in a row, well the top 1 is for moving up. The bottom 1 is for moving down. The middle is the select button.
The 'something' can be found using the search field there ↗️

Thank you! Genuinely curious, what makes you say that I’m more informed than other users? Not trying to be rude at all just wondering.

No worries @SquonkerMoniker, when you said this

 yes but i think its a 316l issue not dna device , also this is my second device in dna 75c , and it is exactly the same for me with ss316l, When it works good it is awesome , but too much playing about with it for me and i do think other materials will work better  . I am no expert but can only report what i have found from my experience . And tried many coil builds, spaced , different escribe settings you name it tried it . I just do not have a lot of luck with ss316l

just do your own research, there are many threads about it, i can only report what i have found over a period of time . When it works with ss316l it is awesome , just not consistent enough for me, so am trying ss340 as it will be more stable in tc mode i think thats all .

Ahh I see. For a while I didn’t really even consider buying a mod with a DNA chip. Then I decided I wanted something that can do awesome and reliable TC. So here I am. I didn’t really do any research on it specifically. I just always see comments praising the DNA chip. Never saw a negative or even slightly critical post regarding the TC.

Yeah I’d absolutely love to know what’s causing your problem.

When you say there are many threads about it, are you talking DNA chips in general or specific to the 75c?

Just google ss316l dna temp control issues , you will find some really good posts to read, but no it is not only dna 75c issue it is on other modes as well as far as i can see , it seems to be to do with the resistance change in 316l ,can make it a bit rubbish now and again in tc mode . I will report back when i have got my ss430 and wrapped a coil, the profile file installed and had a vape . I am expecting it to be very much improved tc experience due to the different resistance changes , after getting some good advice from people on here

If it is all good, then will not even bother with 316l again .

 

[dwcraig1]

Here are some situations that wreck havoc on getting TC to work properly especially when using wire that has little resistance change when heated. Things need to be pretty much perfect for these wires to be read properly by the board.

!st.  is a coil with shorting wraps giving a false cold ohm reading, as the coil starts to heat the shorting may stop creating a jump in resistance.

2nd.A bad connection between the 510's, maybe atty's 510 is too short or has dirty threads on it's 510 threads or loose to wire post.

3rd. Wire not clamped under post screws tightly.

4th. Wrong TCR settings.

There has been some cases where LV put thread locker on the 510 threads where the ground wire connect internally on the 510 socket creating a problem with resistance readings. This was quite some time ago and I have not heard of it since.

Just to name a few, I'm sure there's more

Вот некоторые ситуации, которые разрушают правильную работу TC, особенно при использовании провода, сопротивление которого при нагревании мало меняется. Все должно быть идеально, чтобы эти провода правильно считывались платой.

 

 

Есть ещё несколько нюансов:

4. Химический состав проволоки отличается от эталонного значения, следовально TCR не соответствует, загуженному.

5. Слишком большая масса катушки, при этом алгоритмы evolve просто не могут адекватно управлять нагревом, в результате появляются провалы и скачки при нагреве.

6. Использование провода из нескольких скрученных жил, иногда даёт некорректные результаты TC

I hear ya. I’m looking forward to hearing how that works for you. I’ve looked around these forums and didn’t find a whole lot of posts about this but I did find out more about this topic when I got to googling. 

Was reading about an unstable 510 connection (damaged, dirty, etc) and the initial reading of the base resistance that could cause issues. And then of course you already know about complex coils not always working  in TC as expected. Then I read something about case thermals and internal resistance (which I admittedly am ignorant of) causing issues.

So then I thought that it does make sense that there may be some issues specific to certain mods as opposed to others due to build quality, QC issues, and other physical parameters even if the different mods have the same DNA boards with the exact same firmware, same software config, same hardware used (coils, attys, batteries).

Reading about a guy who’s apparently had zero issues with TC for years. Uses SS430 single wire. So I wouldn’t be surprised if that does it for you. 

I guess should’ve done more research than just going on all the overwhelmingly positive comments about the DNA chip’s TC, but I came across a barely used squonk that’s popular and was just listed fs on a Facebook group and figured the worst case scenario is I wind up with a super customizable mod that didn’t break the bank.

What about replay? How has your experience been with that?

Lol after reading this I’m wondering if you’re the same person who wrote about some of this on the e-cigarette forums that I just recently read.

Спасибо за эту информацию. Вы можете объяснить это поподробнее? Я не совсем понимаю 4.

Bei den genannten / verwendeten Materialien (SS316 etc.) handelt es sich um Legierungen verschiedener Metalle, deren Spezifikationen jedoch leichte Toleranzen in der Zusammensetzung zulassen. Mit diesen leichten Toleranzen variieren jedoch auch die thermischen Eigenschaften. Wenn wir also als Beispiel bei SS316 bleiben, so ist im Chipsatz eine Kurve hinterlegt, welche die Widerstandsänderungen in Abhängigkeit zur Temperatur beschreibt (=> Referenz). Anhand dieser Kurve und einer steten Messung des aktuellen Widerstands der Coil "erkennt" der Chipsatz die Temperatur der Coil. Wenn aber das verwendete Material in seiner Zusammensetzung ein anderes thermisches Verhalten hat, welches nicht mit der hinterlegten Kurve übereinstimmt, kann der Chipsatz nicht die korrekte Temperatur "erkennen".
