  1. You are fighting refinement. The cold resistance between your first post and 2nd post are pretty far apart. Always mate a cold atomizer with a cold Mod. It is even better if you set the mod down for about 20 minutes afterwards(after the new coil prompt).

    Wait for refinement before settling on a temperature to vape at. Don't set your temperature at 455° then try to force your mod to vape at that temperature. With the tank you have and the power you have it set at, I probably would have it set between 480 and 520.

    The DNA won't remember the cold resistance when removing the battery unless you have the resistance locked in. Replace the batteries one at a time so you don't loose power to the board.







  2. Current displayed on the screen is the output current to the atomizer not from the battery. 65w and 17 amps comes out to about 0.225?, sounds about right if you are using a SS coil.

    The dna will read the resistance down to three decimal places. The screen only displays down to two decimal places. So if the last digit is near a 5, it wouldn't be to uncommon to see the last digit rock back and forth due to rounding off the last digit. Normally the resistance should go down after refinement.

    I wouldn't lock the resistance. Just set it down for about 20 minutes with the usb unplugged, then reset the temperature. 

    Atomizer Analyzer is under the mod tab. It may be hidden. Options> User Interface> Manufacturer

  3. Not temp limiting because you can't heat water past 212° F.

    You can increase the power to a point that the water doesn't keep the coil cool, but then you will see the temp keep rising until it hits your limit. So yes, it is effectively running in power mode, but look at the temp it is running at. 

    I just wanted to show that the Temco wire with the Evolv profile was pretty accurate. If I had a nice straight line at lets say 260F, then you would know that either the cold resistance was wrong or the tfr curve was wrong.

    OK maybe I'll give that a try. The one I have now is actually really good at 450F. I take it I can open it and save the profiles as .ecig files and load them onto my device when ever I want. I haven't tried any of the others that came with the Theriion and really the only other wire TC that I use is Ti. I will give it a try. I know when I first opened it it had 4 profiles and this is the latest software for the 75 v1.0.52 or 54 I think. I heard the newest profiles were pretty good but not sure if that is in this version or the beta 1.2SP3


    v1.2 SP3 won't do anything for how a dna75 vapes with SS316. The changes in firmware only apply to the DNA200.

    1.2 SP3 is still worth getting for some of the changes they made in Device Monitor.

    Both but I am new to DNA's I've used SX's since they first came out and I'm used to that vape. This profile is a little better but still not like an SX with TCR set to .00092 at 420F. I don't have the Escribe setting for SS316 I have the Lost Vapes setting and it is way too low. I've heard the Escribe settings are better but this Therion had 7 or 8 Presets and they are set to SE which I found out that their profiles for SS304 430 316L and NI200 are all the same which makes no sense. I'd like to try the generic Escribe one but not sure how to get that.



    Evolv and steam-engine use a tcr of approximately 0.00087-0.00088 for ss316. it can't be calculated exactly because they are curves and not linear. There is an option in escribe to create your own graph based on tcr.
    You should try creating your own wire profile with a tcr of 0.00092 if you want the DNA to mimic your SX.
  6. v 1.0.42 is for a dna200 only

    v1.0.56 is the official version for a DNA75 (it also works with the DNA200) This version doesn't come with the latest firmware. You need to download the updated firmware separately.

    v1.2SP3 is the official version for the DNA250 & DNA60 (it also works with the 200 & 75) It also contains the newest firmware for all the boards.


    Hopefully Evolv will make V1.2 official version for everything and Kill all the other links because they are confusing the hell out of the new users.
  7. The DNA200 has a balance charging chip on board. The input current information was coming from this chip. Since the Dna75 doesn't have balance charging, this info is missing. Im sure Evolv could've added this feature to the 75, but they were aiming for a budget board with escribe to compete with all the newer 18650 devices on the market.

    True, but it would be a nicer user experience to bring the current value up.  It maybe a very small issue within the big scheme of things, but Evolv want this product to be as user friendly as practicable.

    Bug does not just mean an error.



    I think they should just do some renaming.

    The menu item should read "Create TFR graph from TCR value"
    The dialog box should be titled "Enter new TCR value"

    Evolv then should change the default value of 0.006 to 0.000 or just leave it blank.
