Yeah that's why Evolv doesn't suggest resistance locking it. Your coil can creep around a bit as you vape it. On most that means dropping in testing resistance which then means your locked resistance would be too high and the vape would be much hotter.

What I generally run into though is that it detects the resistance a little too low to start with and then by morning it's working fine from point out.

Interestingly it's gone the other way now after consistent vaping.

That's rather annoying 12 hours after initial mount


Cheers for he info.

Is here any way to reset the heartbeat necessary other than remove tank and fire ? Maybe remove and mount. Select same coil

The heart beat is just a resistance checker. If anything you would need to do the opposite and choose new coil just to reset what it has learned. What I think is really happening is that I need to adjust internal mod resistance to the point where a known at rest coil is getting read to a point where it's a comfortable vape. Otherwise I'll have to wait till the DNA works itself out.

Mod resistance is the internal resistance of the device without any atty attached. It is a static setting and once determined it should not be changed.

For best results with attys the device and the atty/coil should be at the same temperature thus the initial "New Coil" reading will need less refinement.

Actually I believe it is the resistance with the 510 shorted to complete the circuit so the atomizer analyzer can read the resistance. You shouldn't press the fire button when the 510 is shorted. But if you did, hopefully the DNA will just report that you have a "Atomizer Short" error and nothing will happen. Two places AFAIK has tools that they sell that you can purchase. Or you can make your own.

THX Bill for explaining to them how to arrive at the determined static setting I mentioned. :thumbs:

And if the device maker properly set the device then the Calibration Tool is not needed. :)

And you can make a tool with just a 510 to 510 adapter and a bit of solder. Adapter about a buck fifty....

I used Daniel's vid to help me learn to make different on device adjustments on my SMY SDNA75, which was a big help since I never owned a Evolv device. I saved the original file setting and as I learn more and experiment, I will tweak the settings to the way I like it.


I can not get a satisfying TC vape off this device with any of the default profiles compared to my picos. I end up having to use wattage mode to get decent vapor/warmth/flavor. I read the whole thread now and started trying to tweak the boost + profile punch to 11 and time limit to 2s and it seems even worse, no vapor at all. I am using a cubis pro with 0.5 ss316l coil and cranked the watts up to the max for the coils recommended range of 30w and have the temp all the way up to 575 and it is giving off almost no vapor. Anyone have any suggestions for a DNA/escribe noob?

edit: I do have a Hana One Mod dna40 that gives a nice vape with the same coil at 27.5w/550f.

In one of Daniels videos he mentioned that the temp curves pre loaded in the DNA 75s are inaccurate. His website has all the TCR values on it and in escribe you can go into each metal type and set the TCR instead of the csv curve and it performs as it should.

But the SMY SDNAs are pre-configured by Daniel.

At the moment... I'm wondering about the accuracy of the Cubis 316 head (ala the Crown's issues). But the 316L setting should be proper.
IIRC... Daniel uses both TCRs and .csvs as appropriate.
But I should have a look at mine, might be mis-remembering what I scanned quickly on his site.

Adjusting the TCR seems to have helped my tweaked boost+ profile, thanks.

Well. Reading this is quite educational. I don't have the ability to make the cooper plug at the hotel with stuff lying around. I'll
Google it. I assume I need to go just to like Home Depot or something and the eBay tools are unnecessary. But I don't have an issue buying die thing like that if it really does help.

I'm more confused now probably but that probably just means some things I thought I knew weren't correct.

I wasn't aware that the dna chips could take tcr values. Unless you mean adjusting the points on the temp curve after loading a csv. If this mod is configured by Daniel is assume those should be correct. And also we should be able to look at stem engine and compare the listed values with what's preloaded right? Or is the assertion hide fishes are incorrect also? I'd be surprised if s mod maker didn't just use steam engine days for their preload on Dna devices.


I just watched he aspire nc75 video. Given the similar function and good ui for on mod configuration it looks to me like s very interesting device. With s low end version at $39 on release day it seems to be stiff competition. I didn't quite get if they're using a dna75 chip with custom firmware or if it is a competing chip ? I certainly would love tk see escribe options configurable on device like that.


It's not great looking but if they license their firmware / chip to other people it could be interesting.

As a final thought this is what's sort of frustrating in owning the dna devices. All if he modern chips seem to require so much effort to use properly.


If my mod and my tank are both the same temp. And I pair them. That should be it. The resistance shouldn't fluctuate. The temp should be able tk he set tk the proper level right away and it should remain consistent. Out side of builds settling upon initial fire I just dhoukdnt need to change stuff.

For me the only convenient way to use this decide right now is locking resistance.


Also as there is no universal standard for temp except whether 420F lights cotton on fire. It's hard to know what temp is normal. But I can say this device ALWAYS needs min 60F more and up
To 140F more the. My other temp Control devices. And the resistance bounces around like a kids birthday party castle. So I'm all
Ears tondo what I need to. But once again I have to conclude that for anyone wanting a nice way consistent vape evolv based products aren't the answer.


Is there a repository for settings in the sdna ? A website ? And would the resistance and case temp Stuff be universal (or close enough) to use across the line? I'll buy a plug and spend hours configuring it if I have to but if I can get 99% with someone else's setting it would help me


Sorry for he length of the post. Typos. and if repeated stuff. It's not intentional and I am reading posts. It's behind my control mostly or is never be able post waiting for perfect.


I'll brush up on my dna procedural knowledge by watching the liked video. It would be nice to know who this Daniel guy is. And even nicer if he did a video on this mod he configured discussing the possible things incorrectly configured and how to correct. If I can get Dna devices working I'll try tk do so. Otherwise I'm going to try the nx75 for a daily beater temp Control mod.

my smy sdna arrived today. wow! vaping is hard now. i'll continue to use my vtc mini for the rest of the day. tomorrow, when i'm sober, i'll go back to school. i just know it's gonna be fun. i see that i will have to put in a tcr value for the ti wire i use and adjust some other things. the ti preset isn't cutting it.

I am struggling as well with the sdna 75. Which is supposed to be tuned by him... The res jumps around all over the place and I just need to fight to get it to vape well.

Try different tanks. All 4 of my SDNA75's work as expected.

I do not have a 75 but I've been using Daniel's titanium curve on my VT200 and I wasn't satisfied neither. It gives me a bit of an inconsistent vape and tends to run about 10 degrees Celsius cooler then the standard Ti setting on my Cuboid mini. I kept all his other recommended settings for this mod but switched back to the titanium profile that was originally installed on the VT200 from the factory and it has been a dream so far. I have to turn it about ten degrees lower then the Cuboid mini to get a similar vape, but can go hotter without it become harsh as quick as on the CM if that makes any sense. The only downside is that my Cuboid mini doesn't really satisfy me anymore now, lol.

I don't know what values are used but I can upload the profile if anyone's interested. That is assuming DNA75 and DNA200 files are exchangeable.

I like Daniel a lot and like what he is doing and everything. But he came out with a list of 510 lengths of attys and they are not even close to what what the manufactures and I measured. :shock:

Hmmm, I think I had a look at that list as well before I even knew who he was & then discarded it because I found too many differences with my own measurements as well...kinda odd, he always appears very thorough. Someone should send him an email, I'm sure he'd appreciate the feedback.

I wrote him 2 times with short questions, no response. His latest video explains he was over loaded with products. He is now focusing on reviews as he has left his day job.

However, I don't believe the titanium G1 preset is any different then the default DNA G1 preset. Other settings maybe influencing a perceived difference?

So I sat down and downloaded the csv from steam engine for 316L. Added it and played around on escribe till it felt better to vape on...hopefully it works better this time. But if some of you have any ideas on how the graphs should work, it would be great. If I have a better understanding of what to focus on , on the graphs, things could be easier to set up.

Hmm, too bad, I guess he gets lots of email.

Not sure what he chose for the SDNA, but on the files I downloaded from his website for the VT200 he uses a different custom curve. I had both profiles on my VT at the exact same settings so I could just switch between them to compare them & the difference in performance is pretty clear.
