Looking at the photo's the DNA looks underpowered given that cotton chars at 420F and the Yihi result looks more realistic because it has started to burn the cotton at 30 above the char point. I own both the Yihi M class and the RDNA40. I personally would not compare them like this because the chips are probably using different algorithms to measure what is going on. At the moment my Kayfun 4 is working on both devices perfectly.

But Greigster's photos show the YiHi charring cotton at 300 F over 100 F below the char point, are you referring to some other photos?

I read on PotV that the YiHi is limited to 50 J and Richard form mod maker has said Temp mode is only currently supported on a single battery, but couldn't imagine anyone wanting to put an extension on the mod.

If we know how we define charring it would be easy. In this photo 450F is starting to look burnt and so it should 30f above the char point. You are assuming that the DNA40 is accurate. Is it a DNA40 or a clone and if it is a clone then the whole point of doing something like this goes right out the window.

Just my opinion, but isn`t it better to treat each device individually and work from there for your future settings. There are loads of Wattage devices that dont match up as they should out there.

@scooby & I seem to be getting a different experience with temp limiting than many others, for us the flavour suppresses the we get from kanthal and I did a few side by side tests in November. I don't know why, but it could be a combination of several things:
The flavours we vape
I vape 100% PG which has a lower boiling point and produces more vapour at lower temperatures than VG this allows to get a very good vape at 400 F and releases cleaner flavour
Coil geometry and style
Temperature we vape at, I never go above 410, if I can get a good vape there I make a larger coil

I also find the pre-heat awesome, I use iStick, DNA40 & Cloupor mini doing DIY or walking the dog and even changing down to thinner kanthal the lake of pre-heat is very noticeable and my ADV is dual 3 mm steel rope wicks at around 32 W.

The dry hit protection just allows me to be lazy and vape a tank dry, like the rest of you dry hits weren't a problem.

Not saying that my way is the right way I just find it interesting that our experiences are so different.

Absolutely, spot on Robby.

I assumed you were talking about the photos on this thread here (I will put below as have tagged Greigster), I do assume the DNA is accurate as it has been very consistent nearly 6 months and I can often tell by flavour if I have it a 400 or 410 F, I stopped testing it months ago as just don't feel the need.

[macmagoo]

The only way to do this properly is with a heat measuring camera, I'm sure P Busardo will be along shortly with a review to tell us how accurate the Yihi is. For me personally I don't really worry about it to much as long as it is not spoiling my vape.

[VapingBad]

Consistency is more important than accuracy as you can adjust to taste for each device, I know of the 2 DNA40 I have read about 5 F differently which is obvious by flavour and I generally keep the one that reads lower to 400 F.

[Greigster]

Here is my take on it so far.

At 300f there was a slight mark on the wick. This was done on bone dry Jap Cotton.

I had previously vaped the coil for a few weeks, just mild dry burns and wick changes.

Decided to replace coil and re-try.

Still slight colour changes to the wick from 400f upwards, nothing below 400f. But I was getting colour changes on the VF clone, so not that much difference.

I have not had any dry hits on the old wick or the new one.

There is no way that that I would try and vape the cotton until it was bone dry as I would re-fill long before that point.

I have to make adjustments whenever I change mods and atties from one to the other, so this is no different. The main reason for me buying it was to reduce the chances of dry hits and burnt juices and in my short time of owning the SX350, it had achieved this......only time will tell.

It is difficult to make comparisons when you are comparing apples to oranges most of the time.

I believe letsavit`s SX Mini M may well have been a faulty one.

I also think that Yihi will receive feedback from early adopters which will result in revisions of the firmware being released.

@scooby, sorry was out for awhile, like the others have said i prefer to avoid the chance of dry hits etc. Compared to some of you i have not done any tests with dry burning cotton on any of the mods, and usually sit around the 410-420F temp range on all of them depending on what juice i am vaping and which device, whenever i have changed coils so far there's been no sign of burning at all. ( i noticed i do seem to run higher in Joules on the SX Mini than i would on either the clone flask or Vaper Shark Rdna

Was there a lot of hype about TC? yup the same as any new atty or mod that comes out, it suddenly becomes the best thing since sliced bread. But do i think it will become the norm? No i feel too many have found it a hassle.

I kind of like tinkering with it, and can tell straight away if somethings not right just through the amount of time i have used them.

[letsavit]

Here is my take....I run around 430f and get a nice warm vape from the DNA40... Do this because I run at temp only (have watts about 5 above the atty limits) temp protection is active throughout the vape. I choose 430f as I like a warm vape and 430f is the max before I burn and taste cotton.

This test was with a DNA40. This test is not useless and I don't need specialist equipment because them burn marks I could taste, hence why I did the test, it's a litmus strip with no variables others than the mods. A flask-DNA40 and the SXmini- ni200-same build.




the DNA40 has been tested with a heat measuring camera and proven to be reasonable accurate so I dont agree I should adjust my mod to 280f to prevent a burnt taste. That's like saying after spending £170 on a mod 12watts is really 20watts, £30 quid yea, not £170.....

I don't know if anyone else has noticed that the mod itself (Yihi SX M Class) gets fairly warm as well, I have mine set to 40J 450°F with a KFL+ @ 0.15? on Standard putting out 4.00v and while I have been reading through these messages from page 2 it got quite warm (I did notice it on the first day and swapped out the freebie VTC4 for a VTC5).

Also has anyone tried a Kanthal build on top, I did a quick test to see if it would go into Power mode automatically, it doesn't, I pressed the + and - buttons to read the resistance at 0.88?, but still remained in Joules and Temp, so knocked the Joules down to 10J (thought 40 would be too much for the Genitank with 0.8? coil) and fired the temp shows 32°F whilst firing, so it looks like it works in Joules as well as Watts (Power mode).

Certainly looks like there's a real problem there,@letsavit have you spoken to the vendor?

Yea, tagged here, filled out web site support form Friday, rang twice today, I'll try monday....

It's a nice mod, mine seems to be fautly, well just reading bobw1951 running a Kayfun at 450f then it certainly is, my kayfuns tasted like shite at 400f...

That definitely doesn't sound good, looks like you got a dodgy one, hope you get it sorted, the Kayfun I have on it is the one I took off my VS rDNA40 which I had been using @ 40w 450°F and found that 40J was about the same vape. It appears to have a good battery life as well.

Hope you get it sorted out on Monday m8, nothing worse than getting a faulty bit of kit.
