I have a suspicion regarding the Ti curves I see on my evic VT and, apparently on the sx mini (which I don't own).

Both mods seem to be way off, requiring a much higher set temperature than what they are actually firing at. The only way to justify that is if both companies used a wire with higher resistance and or higher TCR. Both characteristics of either grade 2 titanium or at least lower end grade 1 titanium. Grades have strict tolerances but there are some.

My speculative guess would be that, somehow, the grade 1 wire they have available in Asia isn't as clean as ours (or most of them). That could also explain why some seem require much higher temperature settings to match a satisfying vape while others (with slightly less pure wire) have better results.

Bear in mind we are talking about 0.0x % variations here or the wire couldn't be labeled as grade 1.

Well she gave me that .0035 number maybe someone should try a .35 build and see if it makes a diff. I don't have Ti but it is waiting for me it would almost take 28awg to do it seems like they would know that everyone is using 26awg Gr1 though. I'm sure they have it in China they have everything electronic.

I bet you are right Tony. I heard the other day directly from a little birdie vendor that deals with Yihi, that they were just sent a stash of Unkamen wire to YiHi. That may get us back in the ballpark hopefully. :D

It is my pleasure Vlad, that is what we are here for to help each other understand this technology. I checked it again after about 18 mins and it was at .248 ohms but the mod was still slightly warm with all the heavy vaping I had done. I will let it settle in a few mins more and check it again.

I would suggest you give the SpiderSilk a try for only $15 I think it would be worth it to see the differences in wire if that is the issue. We both received our mods within a few days of each other and with the same factory date if my mind serves me and the setup I used is very close to yours. My ejuice is my own DIY which was at 73% VG and is about a week old after a few hot baths and lots of machine shaking so it is ripe and ready. I have been using it on my Zephrus and on my Lemo 2, and today on my Mutation X v4 so I know how I want it to taste and vape. I will say that I am finding the dual coil Zephrus the best vape so far with just tons of flavor. This DIY is so much better than almost anything store bought and I am in the baby steps of making ejuice so I promised myself that I will no longer buy pre-made ejuice. So much more expensive and by far not as tasty.

Ok, with all this rambling it is now cool to the touch and is at .246 ohms where I think it will stay. It looks like 465F with 16.5J is my sweet spot with a slightly warm vape. I am now seeing a little more temp jumping up as high as 478F but if I bring down to 10J, which is pretty low, it is more stable. I don't see this with my other tanks and never go below about 22J these days so maybe it is the atty. I will finish up this tank tomorrow morning and report back.
Well I didn't take the Kangertech Mini to work with me but instead was one of those days waking up a little late where I wanted to blow some clouds. You all know those kinda days right? So I took my Zephyrus with me instead. But I am now home and after letting things cool down I put the Kangertech Mini I built last night back on the SXM.

The resistance calibrated out to .255 ohms which is a little bit higher than the 2.46 ohms I had last night. I put all the numbers back to where they were when I left off at 465F and 16.5J which last night was my sweet spot. BTW I have been using Eco mode for all this testing. Vaping it for the last several minutes and checking the temp gauge I see it jumping no higher than 473F, but mostly only hitting around 471F for the high. Vape is still slightly warm and good vapor. So I would not consider this much jumping around at all tonight.

Why don't you try a little lower temp and see what happens?
I did try all different temps but came out with the 465F as working best with this build and juice. Lower temps just didn't justify the full flavor of my ejuice and wasn't warm enough.

Thanks Jim, I tried those settings and I don't get the warmth I'm used to with ni200 and I have to pull on it for like 10 seconds to get anything halfway decent.

I did play around a little bit today with an old IGO W3 setup with duals which did seem to be smoother operationally at least at first but I had to keep upping the Joules at which point I reached 26.5j and received a hell of a terrible burnt / dry or I don't know what it was but it was pretty bad. Don't know if my build went bad, got a hot spot or what but the coils still looked fine and nothing charred on the wicking or chalky flaky coils that I can see so IDK.

But at 19j, .09Ω ni200 coil @440 degrees and I can feel the mouth piece and vapor on the Subtank mini heat up after a few seconds. I'm not really getting that with the Ti I have unless I'm up around max temp. So as it stands now I think I'm just sticking with ni200, It's just to much of an effort for me at this point to keep trying to use the Ti I have. :)

Varitube rocks! I ordered my mod from them back when it first released and it was super fast to get it. I ordered the sleeve a few hours ago and I already have tracking and its set for Friday delivery, no complaints here period!
I agree! I ordered my sleeve late Wednesday after noon & it has already shipped & will be here Saturday.

That's a bummer I wish YiHi would get their .... together on this soon.

I find it hard to throw blame why I'm having problems with Ti when many are not having any problems. Could be the wire, me, my setup, Yihi etc... So many variables in my mind that could be the cause of my problems. I've tried to isolate everything to the best of my ability and only other thing I can think of is to have @JimScotty0 over to build my Subtank mini out for me. ;) No B&M's around here even have Ti yet so really cant even go into one of them and do comparisons or try other wire on the spot.

I assume this is somewhere 200-300 pages back but since I don't have the time tonight to scan back that far: what seems to be the best ni200 build for the STM rba? I. D. & wraps? I only have 28g right now. Thanks!
What I use is 28awg 5 wraps spaced 3mm comes out about .075-.08 works real good for me. I have 6 STM's with that build on it. For me I run it at 390 12J but I don't like a hot vape and it hits temp pretty fast.

I have also found that wrapping the coil counter clockwise and using the opposite part of the screw the side that doesn't pull the leg with soft nickel I have a lot more luck getting a good connection and it doesn't deform the coil because it doesn't pull on it. If you are using tempered you could do it the other way.

I wish I could help you more but I would suggest that you try the SpiderSilk as a reference point since that is the only real difference I think we have. You can find it on eBay but it seems to have gone up a dollar probably due to popular demand for Ti. They are saying 194 views per day for that stuff so folks are just going crazy to find Ti to use on their TC mods. Perry from VariTube is using Ti from SweetSpot Vapors and he says he is just loving the Ti on the SXM. He says it is much much less springy and very clean. He is using a dual coil 7 wrap in 2mm giving him 0.15 ohms and he says the vape is nice. It is not cheap though at $12.99 for 10' that is much more than the SpiderSilk wire. But even the 15' I bought will last me quite a while and I just wanted something fast to check out what the hype with Ti was all about.

Ti-Wire

I do like Ti and will keep using it. The vape is clean too and my vaping perception is that it is at least as good as NI200 and maybe better, but very close. I changed out my wicks tonight on my Zephyrus so this was the first chance I got after a few days of vaping on Ti to see how bad was the gunking which I thought was bad with NI200. It was bad but probably not as bad as nickel. It washed off pretty good, but still blackened with some shiny spots even after several minutes of toothbrushing it clean.

As far as dual coils go, with my Zephyrus I am vaping at 495F using 26J, sometimes 28J and get a fairly warm vape. Never burnt and I have taken it down to close to a dry wick without any burnt taste at all. Just anemia with the juice but I haven't tried the dry wick test with Ti. As long as it doesn't burn I am good since we all know when there is no juice left in the tank and it is time to refill.
