Well Jim,

All my builds for the last 2 months have been between 0.11- 0.12 and I have no reason to change since it is working quite well for me. (Yes I plagiarized your text and changed the numbers) I tried the MAGIC 0.065 thing for a time and notice absolutely no difference YMMV. Also trying to hit the magic number got to be a real PITA.

I would love to know why YiHi thinks 0.065 is Magic?
Well George, I think it may be magic for them because they probably built their algorithm around it as the base point in their formula curves. I have used much higher resistance coils myself and have had good results too. I think they all will work pretty well if your atty is stable and you are within their range. My guess is that their magic .065 number may be related to how accurate the temperature number on the display may be to reality. But that is just a guess as to why they picked that number. I say just build the coils the way you like them in size and feel and if it works well then that is your sweet spot. lol

When PB did his review on the eVic VT and ran the temp scope on the SXM (v2.2) and a DNA40 mod the accuracy was pretty damn good on both of them so my confidence went up a whole lot on TC. The SXM and the DNA40 showed 384F and 385F respectfully when set at 400F. Just under 400F which was the midpoint in his testing and that is probably my personal sweet spot on temperature settings. I was thinking my SXM temp number was just a relative temp number but when I seen the graphs I must admit I was impressed. At 300F the SXM measured 301F which is pretty damn good. Does anybody know what his SXM resistance was during that experiment?

Well I didn't want to wait for a response from some of you who will go through PB's video so I did it myself. He built a .09 ohm NI200 coil on a Velocity RDA. It looked like a 10/11 wrap 26ga NI200 at 3mm to me. For me I like 26ga, but 10/11 wrapped spaced coil is just too big for any mods I have. But with the Velocity it is no sweat at all. So my point is the sweet spot may be different depending on your atty. Also the built in resistance of the atty is also an important variable.

One other note, using Ti, the SXM at 300F was actually 354F, at 400F was actually 491F, and at 500F was actually 722F. Now that it will soon be a different game for the SXM when the Ti upgrade is released.

Now I love to watch PB's videos and his testing methods, but I thing I don't like is that he uses the max wattage or joules setting on the mod for his testing which I believe will cause at least the SXM to try to overshoot the temp and fight to get back to temp. The way that I use the SXM is to use just enough or a little more Joules to keep the temp stable so it doesn't have to cut and increase temperature so rapidly to maintain temp which seems to me at least to keep for a very stable and consistent vaping experience IMHO.

Couple comments on recent posts:

(1) When it comes to temperature control, pbusardo's favorite mod appears to be the SXM. Considering this guy has access to dozens of TC mods, that says a lot. Also, he's not unafraid to criticize the SXM. For example, he particularly wants to be able to adjust temperature as easily as Joules. Overall, I agree with him. Sure, I think has the best TC chip on the market, but it's not perfect. On the other hand, with upgradeable firmware, we're in a lot better position for new features or revised interface approaches than others. ;)

2) The purpose of a beta is not only to test new features, but also to find bugs in the implementation. As much as people want the former, they should strongly respect the latter. I will be very interested to test out Ti once it becomes available for the SXM publicly, but let's not undermine the efforts of those who are making sure it delivers the CONSISTENT results we expect it to have when it is released.

Well what has been the final decision in trying to build at .065. Is it better or not. I have one now that is reading at .064 and seems to be working very well. The rest are .07-.08 just curious haven't been following it too close lately but I know there were a lot of people that thought you should build as close to that as possible to get the best results. It that still the way it is or have minds changed.

I find less wraps rather than resistance gives best vape

As the devices guesstimate temp & we know coils heat from the inside out

Having just 5 spaced wraps seems to work just right

6 is still ok and less than 5 works but vapour volume is affected

Once I go over 7 wraps I have to start dropping TP

Best I have found so far for me is 5x 3mm wraps & works a treat every time with Grade 1 Ti

Static resistance on tanks is a ball ache though & what works every time spot on in the STM's is rather hit an miss in both my K4's I tried yesterday

The air flow is too tight anyway so have launched them in the pretty but not worth vaping cupboard

Agreed

We need to make a list of all the Beta Testers so we know who is going to the gallows if its not right :D

Sold my brand new Eviv-VT today after seeing the Ti upgrade for the SXM was in the works. Didn't end up being worth taking the step backwards (imo). I'll just grab one of those silicone cases and get over the fear of letting my good setup leave the home desk.

Snagged a pair of Sony VT5's from Illum last week that finally got here today. At 11k and running on one in eco mode atm and my battery bar has barely moved.

The paint on both mine is holding up well, even the one that jumped out my hand & did a triple back flip before landing on block paving

See there is an issue of jumping out of TP mode with the VT like dna's have been known to

You wont get that issue with the M class as its your choice what mode you run not guess work by the mod :)

I have one of the first run black/silver versons from Gingervaper and my paint has held up perfectly. Guess i got lucky there.

Never had my Evic jump out of TP though....it's way of doing TP just didn't offer the same quality of vape. Especially if/when you want to go over 400 degrees, which i routinely do on my SXM (I have my doubts the Evic-VT's 600 setting is even reaching 500).

Plus i like to use a Lemo Drop, until i can find a single coil RTA i like better (wasn't a fan of the Lemo v2). Which i shouldn't have to set at 30w if i prefer to vape it at 20.

I agree that understanding peak-to-average heating is an important element to doing TC correctly. When 4 or 5 wraps work great, why bother with large coils that are much more inconsistent? If your coil is being built by a robot with precise requirements, that's one thing. However, when the coil is built to the slop results of wrapping it around a rod, respecting and adhering to the limitations of that approach is better. ;)

Where have you been buying your Subtank Mini AFC base's from? I went and screwed up one of my Subtank mini AFC tonight. Don't ask just note it's not a good idea to try to take something this small apart with a pair of 10" channellock pliers.. :facepalm:
Vlad MVS you have to ask them for the dual air flow if that is what you want. They aren't putting them out till their supply of single air flows are gone but they will sell them to you if you ask same price, I believe 8.99. I picked up some extra RBA decks from them too. Also they are very good with CS one of my air flow controllers for whatever reason had a static resistance of .05 higher then the rest and they sent me another without even asking for the old one back.

Just found this site while looking for a different base my the big subtank and they have what you are looking for. Here is a link. I also know reviewers who use this site.

M Class & Zephyrus say Sunday is not for relaxing

Well not until you try, try again

Got there in the end & worth the effort but for work mon-fri it will be no hassle subtank mini's still

The Zephyrus is a great vape on the SX M but would like a single deck as airy & raised air flow cause if you don't get wicking just right

It's either a biblical flood or starving wick

Ended up with dual at 0.145, with 2x 5 wraps of 26awg Ti

Several attempts later we are rocking :)

couple bucks cheaper than myvape store one. I can't use the spring loaded pin in my big tank on my SX mini M as my device for some reason doesn't like it so I use the 22 mm thing that came with it. Looks ugly sin that is why I only use the tank at home..lol

They have the Subtank Plus base too, which does fit the OG subtank. I don't think the STPlus base has the spring loaded pin.

I looked it's just the regular pin in it. I'm waiting on getting it as I just landed me a Authentic Squape reload and I think if I tell my hubby I just need one more thing then this could be my last post I ever make..lol I told him after I got my SX mini M that would be the last thing..lol Guess I told a fib..lol It never ends
