New eVic VTC 3.0 update... TCR Adjust.

[MercuryVaper]

This is kind of a side note, but how in the world is this mod not getting more recognition in the polls? This little guy is a pretty fascinating device for the little time it's been available. It's just a GREAT mod!

Agree. Great mod. I need more of them.

 

[SmilinVapor]

No, I don't believe the VTC has Auto Sensing for wire type either (very few do) but as Huck noted... like most TC mods it will kick out of TC mode if the wire doesn't show the expected resistance rise.

For the TCR memory slots... when you finish setting any of them in that screen, you click Fire 5 times to exit. The memory register you were on last will be the one used as you cycle through the modes (Power, Bypass, Ni, etc.).

ETA: Uh oh... I just played with it, and it will only display "M1" no matter which register was selected. I hope it works as described, but I don't have other wire types to test it with.

My bad. I didn't mean to imply that it could sense the wire. Until I tried it I didn't realize that TCR M1 showed up as an option. For some reason I thought you set M1 was set for the available modes.

BTW, really enjoying this new update with the SS Crown!

Thanks Jim but I'm not a pro yet. The more in depth you get into something the more you realize how much it takes to become an actual pro at anything. Even most of the manufacturers are just starting to figure out how to properly engineer these things. I just focus on stability and repeat-ability. I can't wait to see if the new firmware works using contact SS coils or twisted 316 wire.

I'm glad that they widened the TC resistance range from 0.5-1.5 ohms. Going to try a 1.2 ohm Crown head in TC mode to see if it works as advertised.

Can you use any of the crown coils in temp control mode, since they are stainless steel and not kanthal?

Set it to TempSS

I just did the update and it automatically went into temp mode. It took me a bit to get it back into power mode and get the keys unlocked. Had to resort to reading the manual. LOL. Anyway, the crown coil question is one I've been curious about and the guy at the vape shop could not answer it. Since the evic mini is SS TC capable, can any of the SS coils be run in TC mode? I have one coil for it that is listed as TC, and a pack of .25 standard crown coils and one .5 standard crown coil.

 

[Huckleberried]

I just did the update and it automatically went into temp mode.

Mine did the same, but it automatically changed to Power mode when I put a tank on it that has a kanthal coil in it.

I decided to try my hand at the TC, never did it before. I have a Crown with a 0.5 SS coil in it, popped it on, changed the setting to TEMP SS, dialed in a temp, changed the watts and gave it a shot. Decided it was too much for me, LOL. It was spitting, I was choking. Not a pretty site. Massive cloud, though.

 

[cmoorewv]

Set it to TempSS

A 1.2 head should not read 1.32.
It will taste muted if you run it at the higher setting.
Check and clean your connection between the tank and mod. Use a q-tip in there.

Also, you have to take the reading with the tank cold.

Why would anyone want to use temp control at 1.5 ohms? That defeats the major benefit of fast ramp up. No?

Mine is reading my 1.2 coil as 1.28 or 1.3 also. Not in Temp mode, though. In power mode. The mod is brand new. I've only used it a few days. It's possible that cleaning the pin and receptacle where they connect will help, but I haven't tried it yet.

 

[Huckleberried]

Mine is reading my 1.2 coil as 1.28 or 1.3 also.

It's pretty normal for coils to read +/- a bit.

 

[cmoorewv]

I plan to test out the subohm crown coils once this 1.2 goes bad. I'm getting a bit impatient. These crown coils are lasting at least 2 weeks. Pretty good.

 

[cmoorewv]

Need more info. muuuch more!

And yes, keep that connection clean and tight.

What sort of info? I'm using the 1.2 crown coil I got to work with my istick 40 watt until it goes bad. I'm not locking in the resistance. It seems to be reading around 1.28/1.29 most of the time. I'm not sure what it reads first thing in the morning. I'll have to pay attention to that. If anything needs cleaning, I'd say it's the pin on the bottom of the tank. I've had it awhile longer than I've had the mod.

 

[cmoorewv]

Reading back @cmoorewv, I don't see anything about how you tested the 1.2 ohm atty?
Did you test it on an ohmmeter?... or is the "1.2 ohms" just what the package says?

I'm not sure what the Crown 1.2s are made of... Are they stainless???

1.2 is what the coil is rated at. I don't have a meter to test it. It's prebuilt. What I mean by testing it, is really just popping it on and trying it out. It's stainless steel. All the crown coils are, but the TC crown they make has nickel "legs". From what I've read, this can throw off temp control a bit, since it's a combo of metals.
As far as the mod reading the coil too high, maybe the mod is right and the coil is off?

 

[cmoorewv]

nm

?

 

[cmoorewv]

1.2 ohm coils aren't really for temp control.

And yes, if the coil is unverified at 1.2 then it's possible it is really 1.3 ohms... unlikely though IMO.
But flavor should not be muted like you wrote earlier.

TAKE YOUR RESISTANCE READING ON A COLD TANK! Then lock.

But it's really better to just adjust your vape in straight wattage (power) mode on those coils.

It wasn't me saying the flavor was muted. That may have been in the post I was quoting. I don't plan to run this one in temp mode. Just asking if the .25 SS coils will work in temp mode with the update, really.

 

[cmoorewv]

Absolutely!... Like they were born for each other!
.25s rock in TC.

Good to hear. I'm just patiently waiting for this 1.2 to go...

 

[cmoorewv]

"nm" = Nevermind.

Four seconds after hitting post reply... I realized it was the Sudafed typing.

I had recalled that of the Crown heads, the 1.2 is the odd one out. It's a single coil.
But I mis-remembered them as being Kanthal, and thus... not for TC. Oops.

Like I said... nevermind.

Thought that might be been nevermind, but I was confused. LOL.

All of the 1.2 ohm Crown heads I've used read between 1.28-1.34 ohms on all my mods. That seems to be normal for these heads. They all read higher than they are labeled and they definitely do work in SS TC mode on the VTC. I've used all of the SS Crown heads in temp control mode without much issue. I run the 1.2 ohm Crown heads in M1 set to 0092. I have to crank the temp up a fair bit higher than the SS316 setting but it gives a nice smooth vape without too much heat (my preference). The 0092 TCR setting runs cooler with these heads and lets you fine tune the heat to a lower temperature range (but at a higher displayed temp setting). If you prefer a warm to hot vape then the SS316 setting should work beautifully.

 

[CurlyxCracker]

Ok, just updated, what tcr value are 316L users using?

 

[CorallineAlgae]

You say that like it's a good thing. The "ability" to use more power.

Besides, do you really think you can use more power with 1.2 than with a nice .2 build?

I've never tried it but I question whether you can apply more heat to a higher resistance (thinner wire) coil successfully.

Low resistance eliminates ramp up time.

It works just fine and serves a meaningful purpose. The mod does a fine job of maintaining a constant temperature and battery life is excellent. I've been vaping on this 1.32 ohm SS coil in TC mode for days and it's been excellent. It took a tank to break in the head but that's normal for these Crown coils.
You have to look beyond your personal vaping style. Not everybody likes an immediate high temperature ramp up time. Not everybody takes a 2-3 second draw. I've intentionally run the tank bone dry three times and it hasn't hurt the coil head. Temp control is doing it's job. I wouldn't intentionally rebuild this head at such a high resistance, but if somebody has these heads and likes TC it's very useful to have the option. This head is vaping better in TC than it does in power mode. I set the mod to run it at much higher watts than I normally would push this head and the temp setting keeps it steady.

One strange thing I've noticed: this 1.2 ohm coil stays noticeably cleaner in TC mode than either the .25Ω or .5Ω heads. It even seems to stay cleaner than the other 1.2Ω heads I've used in power mode. I generally run a Q-tip through the heads every so often to clean the coil and I don't get much gunk at all. That's very different from the lower ohm coils. They usually come out black. After a week of vaping on this head the wire still looks new and the cotton looks like it's seen about a day of use. Very unusual for a Crown coil. I even switched to a darker juice yesterday to see if it would affect it but so far it's still looking almost brand new. I suspect that the smoother vape from the 3.0 firmware might have something to do with it. The mod doesn't "pulse" the coils as hard as the earlier firmware versions. The higher ohms and thick wire in this head probably have something to do with it as well.

Either way, vaping these prebuilt stainless steel 1.2Ω coils in TC mode is an excellent option if you already have them. I'm still partial to using .4-.7 ohm coils, but that's what I'm accustomed to using.

Low resistance eliminates ramp up time.

I saw it written, to think of TC wire as mass rather than gauge or resistance. Higher mass increases ramp up.

 

[CorallineAlgae]

I can confirm that twisted SS wire works well in TC using the new firmware. I twisted some SS wire a couple of months ago and I can't remember if it's 28 or 30 gauge, but it's working. Made a single spaced coil that came out to .55 ohms. It runs a little too hot for my preference in SS316 mode but it's just about right with a 0120 TCR. People who prefer a hotter vape might prefer the standard SS316 setting.

If you like using twisted wire coils and have some thin SS wire that you don't know what to do with, I recommend giving a twisted coil a shot. You get more vapor with it than the standard round wire and the flavor is very smooth. I don't know if it would pass a cotton burn test, but I suspect it will work better with the 0120 TCR than the SS316 setting. The common 0092 TCR for 316L is much too cool for this twisted coil.

 

[CorallineAlgae]

TCR values look strange on the VTC Mini because it doesn't have enough screen space for a decimal or enough zeros. Here are a few values I use that have the VTC mini numbers with the normal TCR values in parentheses.

SS304: 0105 [0.00105]
SS316: 0092 [0.000915]
SS316L: 0092 [0.00092]
SS317: 0088 [0.00088]
SS317L: 0088 [0.00088]
SS410: 0155 [0.00155]
SS430: 0138 [0.00138]
NiFe30: 0320 [0.00320]

 

[CorallineAlgae]

Yeah, I've seen lots of variations on the numbers people post. It's generally obvious to me what most people mean when they post a TCR value in a VTC Mini thread, but I can definitely understand that it causes some confusion. I didn't get the VTC Mini's TCR system at all when I first saw it. It's so different from DNA devices. I think Joyetech could've done a little better to keep the TCR numbers more in line with other adjustable mods. I'll try to be attentive when posting values. You point is very reasonable.

I tried the crown .25 coil using a TCR of 0105 and found I had to increase the temp limit to get as warm a vape compared to the standard SS preset (which is supposed to be for 316L I believe). I was using 60 watts and 245 C with the preset, getting a comfortably warm vape. With an M1 setting of 0105 for 304 SS at the same wattage and temp limit of 245, I got much less warmth and vapor. I had to up the temp to about 280 to get the same effect i was getting in preset SS temp mode. I may just go power mode or continue using the SS preset already programmed in. Aren't the Crown's supposed to be 304?
Edit: and shouldn't I be experiencing the opposite effect? It seems to me that the 0105 setting shouldn't be cooler. Maybe I did something wrong...

 

[CorallineAlgae]

I think the default SS316 TCR is something like 0145 or higher. It's certainly higher than I would've expected going by the Steam Engine TCR recommendations. but it seems to work well enough. I use a lower TCR value because I prefer a cooler vape and a lower TCR gives me a larger "cool" range. From what I've seen, certain SS coils benefit from a higher TCR while other coils perform better with lower TCRs. Using an eGo One mega with a spaced 26g 316L coil I set the TCR to 0092. The same tank with a dual twisted wire 316L spaced coil I prefer the TCR at 0120. I run the single coil Crown 1.32 ohm head at 0105 while the dual parallel coil 0.5 ohm Crown head seems better at either the default SS316 setting or 0120. Honestly, any of these coils seem to be usable at any of these TCRs with enough temperature and watt adjustment.

For my vaping style it seems that single wire spaced coils are better with lower TCRs (0092-0105) while twisted wire and dual parallel wire coils can handle higher TCRs (0120-0145). YMMV

Hi guys,
I've got a VTC mini too with the 3.0 firmware and I'm looking to go into TC mode (I only use kanthal at the moment).

And I'm quite confused with which SS wire to get, as there are so many - 304, 316(L or not), 317 (L or not) and 430 - so which one is the best for TC on the VTC with the most consistent experience throughout and without being put off by the flavour and bumps? Many thanks in advance!

All of those wires will work with the VTC and taste pretty much the same. I almost always use 316 or 316L because it's so easy to find and works beautifully (the "L" just means the metal has less carbon).

I also use 304. It's pretty much the same in terms of flavor. It has less nickel in it than 316 or 317.

430 doesn't have any nickel in it. That's appealing to a lot of people but it isn't as easy to track down in various sizes. I haven't bothered with 317 or 317L.

I recommend getting some 316L or 304 simply because they're the easiest to find (and they work). 26 gauge is the most versatile size wire but 24g is also useful.

Yes I think it's too difficult to read also, mine came already upgraded, I may use the previous version, idk yet.

Joyetech is pumping out so many updates it's easy to get turned around. Especially seeing as the Cuboid has the same screen as the VTC. I'm just hoping that I will be able to update the Pressa 75w with the VTC firmware. It seems pretty hit or miss for some owners. Should have mine in a week. Can't wait to give it a go.

Just upgraded my VTC, loving the new update so far (`15 minutes LOL). If the new Cuboid is as good as this, I definitely want one!

 

[truevapes]

My Uwell Crown coil .5 reads .52 is that normal?

 

[DevAuto]

Yes, it can be ... that is in the range of "normal" tolerances.

 

[Analias]

Holy Moly, I'm way behind the curve with my evic minis. Haven't updated since SS TC got dropped in version 1.03. I have a lot of catching up to do! Thanks for all the chatter Humans, keep it up!

 

[HaileStorm]

I kept mine at v2.00. I like to keep as much info as I can on the screen without substituting one for the other.

I also got my new Cuboid a few days back and I'm really loving it! I just wish Joyetech would give me the option to put the v2.0 eVic Mini screen layout on it. Both the eVic Mini and the Cuboid are fantastic mods, really glad I bought them both!

 

[HaileStorm]

I wanna see a picture of em next to each other.
I just lost one of my minis and I'm going to replace it or maybe replace it with something else if I'm feeling adventurous.

I am with you on that! I want to keep the 2.0 screen! I've resisted updating for that reason alone. It's just vanity, I just like the way it looks.

I sort of want to update, but I'm not sure.

You're losing quite a bit of capability in neglecting the firmware upgrade.

I see that you can enter your own coefficient values and store them in presets, and adds a 316 preset. Am I missing anything else?

 

[HaileStorm]

I don't really know how to mess with those settings so I'm not really bothered by it.

As for the 316 preset, if I understood correctly, is mainly for the new Cubis coils? Not really sure. But that tank does look sweet, looks like a great replacement for my tfv4 mini which keeps leaking on me. Seems like a great match for my eVic Mini

 

[Model_A_Ford]

Different metals have different temp change coefficients(the resistance of the wire as heat is applied.)
So for the mod to turn temp control on at the appropriate temp the coefficient must be correct. If you look at CorallineAlgae's post at the top of the page you can see how for different stainless steels, the coefficient is different.

The 316 preset is for SS316. The Cubis coils are 316, but certainly not the only 316 coil that folks vape with.

I hope I explained that right, I'm a vape beginner

 

[Model_A_Ford]

...I just tried a Cubis .5Ω coil on v 2.0 SS temp control and it doesn't work, at all.

 

[lidl_yogurt]

You can switch to v3.0 firmware and switch back to any other version back if you don't like. You can change to any version at any time.

 

[Model_A_Ford]

You can switch to v3.0 firmware and switch back to any other version back if you don't like. You can change to any version at any time.

by re-doing the update back to the previous version, or once you've updated you can toggle back and forth from v2 to v3?

 

[lidl_yogurt]

Hey MAF, you can really change to any version at any time, think of it more like an operating system rather than a normal firmware.

The crown coils are 316L believe.

I looked up as much info on the Crown SS coils as I could surf on the old innertube. It seems they are indeed 316L. I haven't upgraded my evic firmware yet, so I have questions for those of you who have already messed with TCR values.
1) Does entering the TCR value of 316L make the SS Crown coils perform well, in spite of their Ni200 legs?
2) Can you tweak the TCR values by tiny increments or are you married to preset values?

Thanks to @CorallineAlgae for the post with evic values compared to actual TCR values and the screen size explanation.

Always happy to help when I can Amalias.
1) The SS316 setting works beautifully with the 2 SS Crown coils that I've tried so far as well as the RBA. The Ni200 legs aren't an issue.
2) You can adjust the user defined TCR values in small increments, but it's a little different from other devices. If you plan on using SS more than any other TC wire, then a good starting point for the VTC Mini TCR settings might be:
M1 = 0092 (common for for 316L)
M2 = 0105 (common for 304)
M3 = 0120 (default)

From what I can tell, the SS316 setting has a TCR of around 140. The 3 user TCR settings above generally lowers the amount of heat you will get with SS builds. The lower the TCR number the cooler the vape at a given temp setting. For exapmle, I much prefer to vape my 304SS builds with the 304SS TCR (M2 set to 0105), but it also works with the standard 316L setting. It's vapes cooler with the TCR set to 0105 than the default SS316 setting. Using the new TCR settings starts off confusing, but it gets much easier as you use them.

Strange as it may sound, every stainless steel single-coil I've tried vapes pretty well with any of the TCR settings. It simply gets cooler with lower TCR settings using the same temperature and watt settings.

Dual coil builds are another matter. I'll have to play around with more dual coil builds to get a handle on them. Hopefully we have a few dual coil vapers here that can tell us what TCR settings they find work best. Might have to bust out some dripers and start playing around with them.
