When explaining the hum that the chip produces Yihi made this statement which included a recommended oHm range of .06—.12 oHms for best results, a smaller range than what they show for specs. I have gotten reasonably consistent temperature using .05–.08 oHm builds.
I have not gotten consistent temperature for 1.3+ oHm builds to include two overpowered, very close to dry hits immediately after the device had been sitting idle for some time.
...
Because the technology of M Class is the newest, and supports lower sub-ohm resistance, we suggest a 0.06-0.12 ohm base on Temco Ni-200. You can get the perfect experinces when you build the atomizer with the resistance 0.06ohm. However, if using the resistance above 0.3 ohm or Khanthal atomizers there will be variance and some unexpected behaviors may be observed in Joule mode.
I'm with you there, Pera. I try and keep my builds in the .06 to .09 range. I find that, for me, that seems to be the sweet spot.
I have both the 40 and the SXJ and I find them both to be good devices, like some others I have not had the misfortune to have a wonky 40 so maybe my impressions would be different if I had. I will say though that there really is little reason for the lack of user firmware from Evolv that I can see. They get cloned as is so why not offer that feature to their customers to save them the frustration of rma's? I think if it was a user end feature there would be less distrust towards the 40 than there currently is.
As far as if that was a swaying factor on buying the M class? No for me it is just a bonus. I bought the M because the S class was a well regarded device and it held its value pretty well up to the point of the release of the M. So I figured the device would be pretty solid with them building off of the S.
Speaking of updates does anyone know what the download is for on the yihi page for the sx350j that was released 04/28/15?

hi the less accurate thing is from a few post/comments I've read.. and from some of my usage.. not a statement or hard fact. even just now my mini m refused to read the resistance from my GT2.. been on mini m/gt2 for a week so its not a new setup or atty connection issue.. ohm meter and dna40 reads fine 1st time everytime, just not the mini m. jumps from 0.09 to 0.25.. just not the 0.06..lol took me the better part of the hour and still not there.. sign..
anyhow even if the mini m and dna40 works differently, I still like them both, especially when they work! Lol I would think the majority of issues may not be from the boards, but rather in atty designs and of course users' skill in building/maintaining the coil/wicks. too many variables to get the boards to work the way they are designed for..
That sounds much more like something is amiss with the 510 connection on your M class rather than it being a chip issue. See if cleaning the 510 really well helps.
cleaned it with an alcohol swap and it read fine.. then the dry coil error. not sure how that happened(had a full tank), so used on another mod(dna40), read fine vapes fine too.. disconnect let it cool tried on the mini m again.. no good.. still cannot read the resistance again..
not sayin its a chip issue or anything.. switch to a kf4 and it vapes fine too.. sometimes it happens, just like the dna40. no big deal, maybe tmr it'll be ok again.. or maybe the mini m doesn't like the gt2 anymore and wants a kf4 now.. lol
I was getting some dry coil errors as well with my Lemo2 and found it to be a loose coil connection. I should have clued in quicker being the resistance wasn't stable but that's what my issue was.
I've said before I don't see these devices as being very comparable but I'll do my best. First I think the DNA devices are targeting a different audience than Yihi is IMO. I think Evolv is targeting modders and Yihi is targeting the masses. In part I think this due to the features of each provide. While the DNA has basic minimal features Yihi has included a full set of features and options to fit almost anyone's need.
So based on the specs alone if a person was happy with 40w. with stealth mode and needed to go up to 600 deg. the DNA 40 would be fine for them.
If however you wanted to use it as a mechanical, build coils with larger wire or smaller overall length, or go up to 120w or 50j in temp mode, have the screen auto rotate, be able to lock the resistance, have USB upgrade option, have user defined memory settings stored, have 4 different preheat modes, and stay below 580 deg. then I think the SX350j would fit that need.
I'm not going to go into all the issues the DNA device has had since it was released as they've been stated a million times across the internet / forums. But I will link to some comments that I think overall represent how the vaping community has accepted both of these devices based on what I've read throughout the forums.
At 2:20 and again at about 6:12 into the video.

Vlad1, you spent a lot of time in preparing your comparison chart... well done ..... I only would like to say (for comparison purposes) that Evolv does target the masses as many different devices use their DNA 40d product. They market a board that is specifically designed for Innokin and is in their device and not available to anybody except Innokin. They also have designed their boards traditionally with modders in mind as modders have played a great part in the innovations in vaping over the years. The board size also was first designed (and continues) so that the board would fit in a tube type device.
The DNA40 has a refinement feature and the SX does not. The DNA has auto preheat as the SX has manual preheat. The DNA has a power lock mode and the SX does not. The DNA has an Atty Lock feature. The DNA by design requires less menu driven operations. The DNA board has on board switching as the SX has also. The DNA has provisions on the board for auxiliary switching also. The display is fixed to the board on the SX and is attached to the DNA with a flexible ribbon allowing more flexibility in device design. The SX has the USB connection mounted to the board where the DNA has no USB on the board but an auxiliary USB board can be mounted and utilizerd depending on device configuration. The SX J board is more expensive than the DNA board but not a comparable item as the specifications are different.
The DNA40 does have reverse battery protection and the spec sheet needs to be updated. The Atty Lock feature also needs to be added to the spec sheet.
In comparing the warranty I understand Evolv has a 1 year warranty. Yihi I understand has a different warranty depending on the application. My quick research leads me to think the Mini M class is one year and the board used as a modders board has no warranty once soldered. If this is not correct I will be happy to edit my post.
This comparison discussion is good information and beneficial to those wanting to learn more about both.

Well who they target is only my opinion and your certainly entitled to yours. And in no way affects the features or performance. But the way in which they sell their boards is in general to modders. Hana, Vapor Flask, Vapor Shark etc.. which all fall under the same blanket of "modders" perhaps on a larger scale but still modders IMO.
The limited functionality and "Special Orders" for thing like Celsius or accessories like "USB charger" just reinforce my thought on that.
"For manufacturers outside the United States, the DNA 40 is available as a special order with
Celsius units instead of Fahrenheit. Minimum quantities apply. Contact Evolv for details."
"Evolv offers an accessory DNA Charger which is USB powered and provides a 500 milliamp charge current. Other chargers can also be used. The use on an onboard charger is optional – a removable battery will also work."
The chart shows the Atty lock "Dependant on rev", It also shows preheat "1 mode" as well as Stealth mode, perhaps you should re-read the chart. But at any rate I did my comparison based off of the Data sheets if they're wrong or someone doesn't like the semantics perhaps they can create they're own spreadsheet. As I stated there really is no comparison in these products IMO so I put forth my best information on the topic.
As for the warranty my understanding is it just depends on who you purchased your DNA product from. I believe Hcigar is 30 day, Vapor Shark is 120 days, Hanna may be 6 months. IDK about all the rest so I guess it would depend on who you bought DNA from. As for the SXmini M it has a 1 year device 3 month USB manufacturer.
Edited my post.... missed that you had stealth mode listed. Also deleted asking if you might add some info to your chart. Evolv's pdf (data sheet) has several items that need to be updated. Evolv also has DNA40d boards with differing display sizes also not shown. The large screen version has a replaceable display feature that the small screen does not have. The Fahrenheit / Celsius is a standard feature. There are other additions/corrections not seen on the current datasheet.
I always buy my DNA boards directly from Evolv as I like the Paypal feature...

Maybe a bit off topic, but I think this is the best place to post this... feel free to correct me if you feel this is not a strictly technology comparison post and you would rather not see it here. What is the best build for those (like me) that have both Evolve and YiHi devices and want the best compromise build that allows changing attys between devices? Since both are arguably similar temp control devices I would love to hear from those that have both and have found a happy medium, build wise, that works well on both devices.
I currently built to around .12 and have had good results on both devices with the same atty, but there might be a better compromise others have found. If so, I would love to hear from you regarding your experience.
I have also found the ST mini nickel coils, mine currently running at .18, have been working very well on either mod. I set temp to 410 and25watts on the DNA and 400 26joules on the SX350J and both seem to perform very nicely without any unexpected behavior. The DNA temp limits on longer draws, and the SX rarely goes above 360F. All in all, very good vapes from both.

Can't help ya with the self built coils... don't build them anymore... I like fiddle free...easy-peasy vaping... plug and play... On the DNA device I use Aspire Nautilus, Kanger ST, and Aspire Atlantis nickel pre-built plug and play coils and working good for me. Giving the new nickel coil cartomizers (0.27 ohm) a go in a carto tank now..and was surprised at how well they work as far as carto tanks go.... lots of nickel pre-mades have come out....
I haven't give the Atlantis nickel coils a try yet, but definitely on my todo list since the Atlantis is still my favorite fill-n-go for conventional wattage tank vaping. But I'm also interested in the happy medium for my RDA's like the Plume Veil, Derringer, Freakshow, and others. I'll try some more experimenting this weekend, but I would certainly appreciate any insight others have into this subject.
Preface I don't build coils anymore....In looking at the specs and the min and max range of both 0.10 to 0.30 ohm seems to be the range to consider... in other words it could work within the specs shown in the respective specs sheets (Temp mode/Joules mode)..(DNA specs is 0.10 to 1.0 and SX is 0.05 and 0.3)..how well the vape is between the two I think depends on how each device regulates temperature (accuracy) at all resistances and power levels.
Comparison of temperature captures by Pbusardo in the Mini M and DNA reviews he did.
Pbusardo and the temperature readings he captured for the Mini M with the camera: ( 11:00 thru 14:30 )
Pbusardo and the temperature readings he captured for the DNA with the camera: ( 21:50 thru 24:00 )

On the warranty does anyone know if Evolv will repair a Hcigar, Vapor Shark, Hanna etc.. once it's out of warranty with the vendor? Or is the consumer just screwed if for example the Hcigar device fails after 30 days will the customer have to spend out of pocket to have Hcigar or to have someone else repair it for them or will Evolv do the repair for free under their warranty?
