Don't know if this has been covered in this thread or elsewhere, but there's a new TCR adjusting mod on the way. From smok, of all people!
After the horrible debacle of the M80 Plus, they're now releasing what appears to be not only a proper 160W TC mod, but one that also has TCR adjustment. The Smok XCube II.
It has memories, it has TCR adjustment, and this is all manageable via Bluetooth. Which could be pretty awesome.
But of course, Smok being Smok, they had to do something tacky and dumb. It would appear that you don't get TC for free, out of the box. You have to use the Bluetooth app to pay another $3 to get it. Why? Why, Smok, why? Do you have a pathological need to annoy people?
Anyway, there are two things getting me very interested in this mod.
First, this is a screenshot of the Bluetooth phone app, showing TCR adjustment:
It would appear from the screenshot that the TCR range is hopefully quite wide - perhaps 0.001 to 0.010, meaning it will work with Stainless Steel, Titanium, Resistherm/Alloy 120, and of course Ni200. Can't be sure yet, but the indications from the screenshot are positive.
Second, and really quite interesting, this is a new feature that would appear to be a way of setting the Static Resistance of the atomizer. Or maybe the mod. Either way, it's a resistance adjuster - as the DNA 200 sort of features, and as we talked a lot about in the early pages of this thread. Ie, ultimate accuracy by setting the exact resistance of a coil, accounting for SR in the atomizer (and 510, mod wiring, etc):
Here's the page 'describing' this new feature - but the English is too poor to be absolutely sure that it means what I hope it means. Quote below:
I can`t believe what SMOK wants to have implemented. They are not talking about static resistance only, they want to read a wobbling resistance. There are still too many unknowns to calculate the static resistance just by powering and measuring a coil.
- you never know the real TCR of the wire
- you never know the accuracy of the TCR setting
- you never know how your coil type and possible hot spots effect the resistance
After a couple of month with TC I came back to where I started - dry cotton tests. I don`t care about the real TCR of my wire, or the static resistance of my atomizer, or the ohm issue of my SXK Mods anymore. I just do my cotton test, set the temperature to 420F and increase the NP setting until the cotton is brown. After having found the NP setting, I can play a bit with the temperature setting ( +/- 30F ) to find the sweet spot of my atty. The results for Titanium and V2A wires or static resistances are better than ever. All these unknown factors will be compensated by the NP or whatever the coefficient is called. It`s not as accurate as a temperature measurement, but better than all calculations I made.
Nice to have you back Tom - all the best to your father
Happy you are back Bloke and your dad is recovering. You sure have made progress from your early IPV4 video. I am following along...let the education continue.
This is certainly a great empirical methodology. I must incorporate that myself. Removes a lot of the theoretical stuff that is sometimes a bit opaque to me.
Hmm, we could build a partially observable markov model using read resistance and ambient temperature to guess the real resistance after a few trials but you would probably need to have the mod hooked up permanently to a computer workstation to calculate the scenarios fast enough between draws
Ok... I'm sure I pretty much lost my mind lollllll. I'm going to bed.

Welcome back @TheBloke
And a FYI for everyone, YiHi released the test version of the standalone SX350J Ti (not SX Mini M) firmware today. I just installed it, seems to be working so far.

Good to have you back, and glad to hear that your dad is recovering well!HeyI'm back! I hope anyway. Dunno if @TheotherSteveS passed on the news, but my Dad was rushed to hospital three or so weeks ago, and things have been pretty hectic since then. He's been out for a few days now and is making a good recovery.
Anyway, glad to see this thread still going on. Anyone feel like summarising the last 10 or so pages for me?
I bought some more toys!
Firstly, arrived a couple of weeks ago from China via eBay - £35 / $50 four-wire/Kelvin probe micro ohm reader. Suck on my digits, baby:
(OK so it's not actually accurate to micro-ohm. I probed it with my DMM and it sends 0.1A / 100mA of current. Which is great compared to most DMMs, which often send no more than 1 or 2 mA, but nowhere near the up to 10A that a proper micro-ohm reader should send. So at most it's likely accurate to milli-ohm, 0.001Ω. Still pretty good though I think!)
Secondly, ordered today and should be here tomorrow.. bit of a luxury. Ok a huge luxury.. but I'm gonna be doing some proper scoping of these mods methinks:
A Rigol DS1054Z four channel 50mhz (hackable to 100mhz) digital storage oscilloscope. I'm gonna do me some Busardo-style mod scoping! I hope.
Anyway, hello everyone
What I do want to do aat some point is take a look at the SX Mini M Titanium firmware - can anyone tell me if it's still not working right, as I've been told?

Thanks everyone for your kind words! It's good to be back. I probably won't be on quite as much as I used to be, at least in the short term, but I do have plans to do lots of testing and hopefully post some stuff up soon.
Over the weekend I got my oscilloscope and at first I thought I'd made a terrible mistake and wasted a lot of money because I couldn't get crap out of it and it all just seemed weird and annoying and not appropriate for what I wanted it for. Then I read the manual Now I actually have some working scans out of it and I think it will be quite interesting to use going forward.
I just bought the Smok XCube 2 which came in stock today at My Epack in the UK. So should have that tomorrow or the day after. Be interesting to see how the TCR stuff compares.
Can you elaborate? What is your understanding of what Smok seem to have implemented?
What I thought it was was a way to adjust the initial resistance reading of the atomizer. Eg you put the atomizer on, and the mod reads it as 0.537. But you know that in fact it's 0.520, so you adjust it down.
What confused me though is where it says "+/- 50mOhm". What is that about? It seems like a margin of error, but 50mOhm is a huge margin of error. For good TC it should be accurate to 1 mOhm. So I don't really understand that.
But you think it's something different? A way of fixing on a resistance that is changing over time?
True, but I think we can measure it with a reasonable degree of accuracy - as long as we have one Known Good Device, we can use that with a temperature probe (thermocouple) to test:
a) Unknown wire against known-good TCR setting on mod
b) Unknown TCR setting on mod against known-good wire
It is not perfect - at least not unless we invest in $000's equipment - but I think it can be good enough.
Example: I used the Dicodes and its TCR setting to validate the TCR of Zivipf's Titanium wire as 0.0035. I did this by setting the Dicodes to X °C, and then changing the TCR slowly from 300, 310, 320, etc, and measuring the temperature. Once I reached 350 (0.0035), the thermocouple showed that I got the accurate temperature that I had configured on the mod.
This is not a perfect test of course. But as long as we have one known good device that we trust as accurate, we can use it to get a good idea of the TCR of wires, and then use those wires to test other mods.
For example, when I get the Smok I will do the following tests:
Once I am confident of the wire result, I can then use that wire to benchmark other unknown-quality TC mods.
True, but I think with spaced coils which are relatively consistent, this can be discounted as a major factor.
Incidentally this is one reason that I prefer Resistherm / Alloy 120 as my primary wire. I can dry burn the coil before using it, and confirm no hot spots, even glow across the coil etc. I find this preferable to Titanium where I can't do that. (Also, I can then easily clean the coil by dry-burning it clean when changing liquids etc.)
Yeah I understand and that's fair enough.
I've said all along that this sort of advanced testing I do is not necessary. In the last weeks when I haven't been on the forums, I haven't done any testing. I just made a bunch of Titanium and Resistherm coils, and set my TCR mods to the right TCR, and my non-TCR mods (DNA 40, SX Mini M, etc) to around 140-180°C depending on mod, and got a vape that was always 'good enough'.
It was surely never super accurate, but that was fine.
The reason I do all this testing is mostly for interest/fun. But also, sometimes it is useful - for example, those Titanium-on-a-DNA40 tests I did some weeks ago, they gave me the fairly accurate °C numbers to use on a DNA 40 with Titanium - which I could then easily convert to Resistherm as well.
But I do agree that the hardcore calculations, like for adjusting for Static Resistance, has no huge value for most people. At least it doesn't when we have to do it by hand.
But if there was a feature on the mod - "enter Static Resistance of Atomizer" - then why not use it? Especially if you know your atomizer has a high SR, like 0.04Ω. In that case, it is almost no effort to use the feature, so why not try and make it a little more accurate? But I agree if it's a lot of work to use, there isn't huge benefit.
Actually I already asked Evolv for that feature on the DNA 200, to be added to Profiles. It would be very easy for them to add. (I didn't even check yet, maybe they already added it? Probably not yet though.)
Anyway, must run now. Will post my findings on the Smok once I get it!

For example, when I get the Smok I will do the following tests:
- Using Dicodes, validate Zivipf and Crazy Wire Titanium wire with TCR setting 0.0035 - is temperature accurate?
- This test re-validates my earlier test of this Titanium wire, confirming TCR 0.0035 is accurate with this wire
- Using DNA 200, validate Zivipf and Crazy Wire Titanium wire with TCR setting 0.0035 - is temperature accurate?
- This test is a new test designed to validate the Dicodes accuracy - I expect to see same results as in test 1
- Using Smok XCube 2, use Zivipf and Crazy Wire Titanium wire with TCR setting 0.0035 - is temperature accurate?
- If I get accurate temperatures, then I can be confident that the Smok is accurate - because it will give the same results as two other accurate TC mods
Once I am confident of the wire result, I can then use that wire to benchmark other unknown-quality TC mods.

I didn't check til just now, but the YiHi update I mentioned earlier goes up to 75J. I'm going to try building my Royal Hunter with Ti tomorrow and see what happens.
The way this is going, I might have to sell my unregulated dual 26650 box...

@TheBloke
Just short, it`s late again. I understand why you do and did all these tests and research - I like to do it too. I learned a lot in this thread and most possible factors of TC vaping are implemented into my brain now. I`m thinking about buying a Uni-T temp meter too, but for playing with it only. I don`t want to measure all my atomizers.
Smoking was easy and vaping should be easy too. That`s why I came back to dry cotton tests. When I rewick an atomizer I check the coil 20F below my regular setting and that`s it.
The truth is on the field, said the coach.

I almost completely agree with that.
That said, I am having more fun building coils and playing with wicking than I've had in a long time.
I'm really enjoying knowing HOW these things work, too.
Still, at the end of the day, the adage "if it ain't broke, don't fix it" might apply.
If it don't burn the cotton, don't worry about it.
Did you also do the temperature offsets for Dicodes Resistherm on the DNA 40? Or could you at least provide some rough guesstimates? I've read the whole thread, but I can't remember if it has been mentioned before, sry.The Titanium used is Zivipf 0.39mm / 29G, already known to have approximate TCR 0.0035. Other Titaniums may vary (but hopefully not too much.)
I'll actually be running it on an iStick, but I assume settings might be the same since both devices are calibrated for Nickel.

Ok, but what if my bloody coils don't burn the cotton when testing (i.e. fully dry) but burning when I actually vape on it??
Luckily, it is cosmetic burn only and no bad taste whatsoever but still annoying.
For the record: it is my Ti coils. Neither hybrids nor A120 does anything like that.
Troubleshooting is on, trying different builds, devices, wicks, even PG/VG ratios. Keeps me busy
I don't know if its mentioned before but I saw this at intaste.de
wtf is that thing? lol
BUJA-W74 resistance wire - InTaste
It says
The BUJA-W74 heating wire is made of 99.5% tungsten and features a very fast response time. Due to the low resistance in combination with the strong increase in resistance heated When the High Performance Wire is therefore ideally suitable for temperature control. The 0.30mm diameter Allows the BUJA-W74 to be processed wonderfully.
It also says that the increase in resistance is 100C ° / 44%
So I guess we should know the TCR number by that info above?

No, I haven't as yet. But the TCRs are so close - 0.0032 vs 0.0035 - that you can just use Titanium as a guide. I simply knock off 5°C / 10°F from the setting I would use for Titanium.
Be aware you probably can't use the DNA 40 testing as a guide for the iStick. Certainly it's not a guide for many other mods, like Yihi chips. I run Titanium at 140-150°C on my Yihi SX Mini M and my IPV4, where I use 180-185°C on the DNA 40.
The iStick is far more likely to be like the former than the DNA 40, hence 140-150°C is a good starting range, and therefore Resistherm would be around 5°C lower than that.
I do have plans to test other mods with Titanium and Resistherm in Ni200 mode - including perhaps the iStick 40 at some point, as it's so cheap.
I'm currently building a test rig that will make it a lot quicker and easier to do future temp testing, but I can't promise when I will get to such tests as I have a mountain of things to do both in and out of vaping.
Great find, thank you!
I'd previously written off Tungsten because although the TCR is great, the resistance is so low as to be nearly unusable. I hadn't investigated Tungsten alloys, and that's what InTaste seem to be using. 99.5% tungsten and I guess it's the 0.5% that slightly increases the resistance, enough to be usable.
But 1.0Ω/m is still very low - lower than an equivalent thickness of Ni200. To be precise, Ni200 at 0.3mm (Between 28 and 29 gauge) is 1.36Ω/m. 1.0Ω/m is closest to Ni200 at 27G.
That's not unusable - plenty of people are using Ni200 at 28G and even 26G - but it's still very low and one of the (many) reasons Titanium, Resistherm and Stainless Steel are preferable over Ni200 is the higher resistance and the benefits of that: lower power requirements, easier to build with, wider range of builds available.
So what I'm wondering is whether Tungsten can offer anything over Titanium, Resistherm and SS that would make it worthwhile going back to ultra low resistance.
And then I look at the price. €13 per five meters - seriously? Exactly double the cost of Resistherm which was already really expensive. 5 - 10 times more expensive than Titanium.
Anyway I'm going to order some, in the name of completeness
But I don't hold out hopes for it being the new wonder wire. It should be dry burnable and therefore I can see it being better than Titanium (though not likely so much better as to justify the extra cost) but I can't see how it could really beat Resistherm/Alloy 120.What it does make me wonder is whether there's a generic alloy that would be far cheaper - like there was Alloy 120 to Resistherm. I'll do some googling, or maybe @vapealone knows?
Anyway, great find - thanks!
Speaking of dry burns: a few days ago I finally went back to Stainless Steel, for the first time since I started this thread.
I've only made one coil, but it's working really well. 8 wraps of 25G SS317L, coming out to about 0.48Ω. I'm running it at 215°C on the Dicodes, with TCR set to 0.001. I used to use 0.00105, but based on @vapealone 's research into the TCRs of different alloys, it seems 317 has a lower (worse) TCR than other alloys. Which incidentally makes me want to try some SS304 as I think that might match the 0.00105 that Dicodes quoted for SS. I see that wireandstuff.co.uk are selling 304 so I might get some at some point.
215°C is a fair bit lower than I run most Titanium/Resistherm builds. I think this reflects the inherent low accuracy of SS. My guess is I am in fact achieving around the 230°C that I normally target, it's just that with SS you're only getting accuracy to the nearest 30°C.
But, as Dicodes said in their Applicataion Note For Temp Controlled Vaping, it's not the accuracy that is of prime importance. It's the repeatability. It doesn't matter so much if the number on the screen is the actual real temperature. What matters most is that we can achieve a TC vape that tastes good, doesn't burn when juice runs out, and can be readily repeated.
So far I'm very pleased with the SS coil. It does taste good, it doesn't burn, and I've been vaping on the coil for several days and it's holding up perfectly.
And the best part is that it's proved to be dry burnable. I changed juice on that coil last night, and was able to remove the wick and then pulse the coil at 20W VW until it glowed red, to completely clean it out and remove all traces of previous flavour. The SS coils glow perfectly, just like Kanthal, remaining strong.
The other big advantage of dry burnable is that contact or part-contact coils are much more reliable - you can test fire the coil, dry burning it to check it has that nice inside-out glow, and that therefore there are no hot spots. I've found that's useful even on non-contact coils, just to be sure the coil is firing right.
Stainless Steel is very cheap - much cheaper than Resistherm - and therefore I think it's definitely a worthwhile TC wire.
But the big downside is that, currently at least, its use is limited to a small range of mods. Unlike Titanium and Resistherm, you can't adjust temperature on an Ni200 mod. You need a TCR adjusting mod. Right now that means Dicodes, DNA 200, or the SXK mods - though the latter are not going to be as good a vape as the former two. There's also the new Smok XCube 2 which is a TCR adjusting mod, but annoyingly won't go lower than 0.00150; 50% too high. That likely will work to some extent for SS with a temp adjustment, which I haven't tested yet. I do plan to contact Smok to ask them to lower the TCR to 0.00100 in a future update, enabling full Stainless Steel usage.
TLDR: If you have a TCR adjusting mod, give Stainless Steel a try! It's cheap, strong, dry-burnable, and gives a good repeatable TC vape. Just be aware you might need to play around with the target temp to find the right spot, and that might be 20-30°C (40-60°F) different to your 'normal' temp.

Is this the resistherm wire you are talking about TheBloke?
nife30 resistive wire - le petit vapoteur
I've been using Ni200 for the past 8 months but a friend sent me some old studies (really old from 1992) about nickel that is so fragile to spread ions that are harmfull and I'm having seconds thoughts, I'm ready to change the wire I'm using.
Not that I had any problems but my friend who isn't familiar with e-cigs somehow has convinced me.
All I'm saying is that I would like to use a wire ( resistherm maybe? ) that no one can tell my about nickel hazards or titanium oxides and stuff like that.
I hope to read more of your findings about resistherm or another wire that is solid to use and maybe one that can be used with our current devices.
I don't own yet a chip with TCR , I only have dna40 and sx350j so it would be ideal that these devices work with it.
Due to capital controls in Greece, we can't order from abroad until 20th of August, if I could I would order both resistherm plus titanium.
So I have to be patient for the next few days as I'm stuck with Ni200. Kanthal is not an option for me cause I hate burnt taste, something that I almost forgot these 8 months I am using TC.
Keep up with the testing TheBloke, we all support you, it's a pity really that so many companies release so many devices and no one is testing what the final user vapes.
This is my favourite topic in the forum btw...
nife30 resistive wire - le petit vapoteur
I've been using Ni200 for the past 8 months but a friend sent me some old studies (really old from 1992) about nickel that is so fragile to spread ions that are harmfull and I'm having seconds thoughts, I'm ready to change the wire I'm using.
Not that I had any problems but my friend who isn't familiar with e-cigs somehow has convinced me.
All I'm saying is that I would like to use a wire ( resistherm maybe? ) that no one can tell my about nickel hazards or titanium oxides and stuff like that.
I hope to read more of your findings about resistherm or another wire that is solid to use and maybe one that can be used with our current devices.
I don't own yet a chip with TCR , I only have dna40 and sx350j so it would be ideal that these devices work with it.

Yes, that is exactly the wire. This is where I bought it from, the Pipeline store in Germany: Dicodes Wire Resistherm (NiFe30) für den PIPELINE PRO 2 - für eZigaretten
Its full name is Resistherm NiFe30. Resistherm is a brand name, like Kanthal is. The generic name for this wire is Alloy 120, which can be purchased for much cheaper, but only in huge quantities - eg $50 + postage from the US, for 300 meters (yes, 300!)
I've posted about Resistherm quite a bit in this thread, so do a search and you will find a lot of my findings.
It has two downsides: a) Cost, €13/10m, b) it's only available as 29G (0.25mm)
Because of b), I only use it twisted. I twist 2x29G Resistherm strands. Of course this makes it even more expensive, €13/5m / €26/10m! (Which actually is the same price as that InTaste Tungsten wire, but because the Tungsten is only 0.3mm, I think I would want to twist that too, making it €13/2.5m / €52/10m!!!)
Twisted Resistherm is currently my top favourite TC wire. The TCR is similar to Titanium, so it is accurate for TC. It can be used on all TC mods - TCR adjusting, but also Ni200 mods using temperature adjustment (I use 165-180°C on a DNA 40, and 130-140°C on other Ni200 mods such as Yihi.) It is strong, and has a high max temperature, and is therefore dry burnable.
I am using Titanium as well, but that's mostly to save the hassle of having to twist Resistherm.
I keep meaning to get some Alloy 120, which is the generic form of Resistherm, and very much cheaper.
So I can highly recommend Resistherm, it is well worth trying.
