Well I am back to report that the mini reading .11Ω provided the useless anemic vape we have been finding all along... :-x

I can tell things are NOT going to work when I quickly tap the fire button and the starting temperature is anything other than 70F, a failure shows 175F, 190F, 204F etc. So I brought it back in and shut it down, unscrewed the FeV, fired it a few times put the FeV back on etc... I took the battery out and put it back, shut it off on on a few times and so forth.

Then all of a sudden the reading went to 0.14Ω and stayed there, still no ask of a new atty but every time I hit the fire button quickly it was 70F, leave it for a second and 70F again. Back outside for a vape and the mini performed flawlessly! I had to turn the temperature down as it was a little too warm, the vape was very similar to my default 26g 0.7Ω standard Kanthal build in the FeV.

I was happy that this was going to work! :banana:


Came back in, got a coffee and the resistance was reading 0.11Ω again... Sneaked a quick vape and it might just have well been an eVod... :(

While I am typing this I was playing around with and had the mini detect the coil at 0.16Ω buy unscrewing the FeV just till it barely made contact. I screwed the FeV back down, the mini kept the 0.16Ω and it vaped perfectly.

I am done playing with this thing till my Ti wire gets here, I do not have an RTA with a big enough deck to hold a coil of 0.14Ω or larger and I hate building and wicking with 30g.
Try this first. Stop locking your resistance. If that doesn't work try building above .15 if possible. Seems people are fixing this problem with either of these steps. Also try taking your atty off when cold, try to fire w no atty attached, go through the menu to lock res if you really want to and attach cold atty then hit the one button to lock res right after you attach atty. These things have been fixing the issue for longer amounts of time, but I'm glad to hear you are getting yours to work at all troll. I understand you've been experiencing this problem probably for the longest.

Guys..i have the same issue and i decided to rebuild my 4 attys..

3 authentic subtank mini, nickel 28g 0.1-1.6ohm
1 authentic lemo 2 - titanium 28g 0.32

Lock resistance at room temperature but the resistance still jumping all over the place..

Been thinking should i change to other attys or dump this mod to my graveyard box and out of sudden recall vaping turtle will using KF with no temp issue..

Dig out my graveyard box and manage to find old KF and Russian 91..

KF Clone nickel build 0.15
authentic R91 nickel build 0.13

Lock resistance, temperature set at 420 18w..test fire and rest the attys for half an hour..vape for 5 min..yipee, no issue on temp control.

So far i been using both attys for more than 2 hour, no issue at all..
Perhaps it is the attys were using. Tanks/drippers of similar design seem to be doing a similar thing. Try unlocking your resistance if you feel like using a different atty tho.

Springs can do that and that with poor atty connections is why res locking become popular with customers, the main reason with board designers is cost, less R&D + can use cheaper 510s & wire.
But if the spring is causing res fluctuation, it would throw the chip off causing the problems we're seeing. It would effect accuracy, so why res locking is in place, if it doesn't lock it in the chip as well, is beyond me.

Not at that price it's not, but I supported my local B&M and picked one up there. I paid double that price in CAD, I wanted it NOW and supported the local vape economy in the process. :facepalm:

It's a buyers market these days for you guys with your strong dollar and cheap stuff out of China. We are lucky to get 70c on the dollar and our money is now on par with the Lybian Dinar... Ole KaDaffy Duck would be proud if he was still alive... :lol:

anyone knows how to fix the "Protection" problem yet?lol
Read my last few posts closest things to fixes we've found. Probably poor atty connection/res locking issue/not sensing new coil/510 and spring issues. Chip does seem to be working as intended, when it does work correctly, for nearly everyone so far.

You are correct it would give the chip problems, but the base/cold reading is the most important and locking that is a cheap fix that reduces the effects so has become a popular idea.

Good Sir,

I followed the new set of guidelines that @VapingBad posted and @zeus01 had success with. You can see by the pic I posted that the resistance is NOT locked and wasn't through out that whole test. It would not matter if I did lock it in around 0.16Ω, as soon as the device goes to sleep it comes back with the 0.11Ω reading again it adjusts the vape automatically.

I have absolutely no desire to build a 0.15Ω coil from Ni-200, with 28g there are just too many wraps needed and I don't like to build with 30g at all. Thanks for the suggestions though.


I believe the eVic VTC Mini was tested in the factory ONLY with the Ni & Ti coil heads that are 0.2Ω and 0.4Ω respectively. I doubt they did any RTA building since the mini works with a coil SKU they intend on selling.

The specs for this device state that a TC build can be as low as 0.05Ω, so a 0.1Ω build should not have any problem working properly.

I'll revisit TC again when the Ti wire gets here and I can put a build of 26g, 8 wraps on 3mm for 0.35Ω in just about any RTA I choose to.

I'm starting to wonder if the lack of "New coil/Same coil" question has something to do with our quick three-click processes to enter the menu to unlock/lock a new atty.

Usually I do not take any attention at all to the screen when I'm three-clicking it to unlock the atty (because I've just changed it, and I really know that....) and doing so I miss the message, which surely qualifies as backup/security question to absent-minded ones....if it appears, that is!

But I'm happy with my 1.10 upgraded one. It almost never asks for anything more than e-liquid, batteries and user input on new attys. Sometimes (and because you forced me to take notice of that) I've discovered the message, if I was lazy enough three-clicking it.

No dry-hits, never. Not even one. Absolutely the same experience that the IPV D2 provides, taking exception of the different TCR for nickel wires, which forces me to adjust temperatures about 20-30 ºC below in the IPV, but anything else is about the same.

Watching a good movie and reading a page-turner book would never be the same. Now I discover myself looking for the missing vapour, not the dry-hit, when things get interesting.....:thumbs:

Hey I think my mod just learned I was cheating her (yes its a her) good thing I read what you've done,did the same thing basically,what's weird about it is it worked fine at home then here at work it happened I highly doubt t that it's because of air conditioning ????? That's the only thing different,

Hmmmm


Weird but so far seems like unscrewing it from sleep,for it to work.again is on,hopefully an update should fix this,
Any ideas of soldering a solid positive pin to replace the spring loaded one?

Understood. Just so you know some people are having the problem with the stock or clr heads as well. It's been mentioned that the lower you go in ohms the bigger the differences would be at the 510/spring loaded area, if they are creating any differences that the chip is not picking up on. I'm not sure that it is low ohms or 510 connection or the new coil message or the locked res. But it is something besides the chip, as once the correct steps (whatever they may be) are taken, the device works as intended.

Thanks Jesse, I wasn't aware of that.

I apologize if my previous reply came off a bit harsh, but I was hoping for a fix and was a little peeved at the mini at the time. The FeV is back to 26g Kanthal and working like a charm again...

I don't use coil heads so I probably skipped over those posts. If they are having trouble too, then it is my belief this has to be a firmware issue for sure, I just can't see the floating pin causing this.

so a biut more detailed on the unlock lock resistance thing

so i am now on a single coil 0.28 ohms
initial vape was meh,

repeated the step that was provided earlier,
worked like a charm.

then rested the mini,
vaped,then meeeh again,

this time i just unscrewed the rescrewed,
works ok now,

will try a bit later on the locked resitance see if it works better

what baffles me
is when the resistance is unlocked
vaping 380f
feels like vaping 480f on a locked resitance...

Man I was experiencing similar issues with hitting the temp protection right away all the way up to 600 f and getting no vapor and solved it by

No atty attached
Turn device on
Get to lock screen
Screw on atty
Lock

Resistance will read let's say .19. After first fire it will read .17 and work flawlessly all day and stay at that .17. When I refill I make sure it has had time to cool. Then repeat steps. Have even been swapping back and forth between two attys with no problem doin these steps.

This has worked every time. But it sounds like some are having zero luck. I sure hope there aren't deeper issues because I just returned my wife's istick50 and got her one of these to replace it.

She is gonna drive me nuts if she can't get it to work right.

What hardware version do our users with problems have?

I have v1.02 running the v1.10 firmware. (I guess it has already been shown that the firmware update to 1.10 shows no improvement to the users with problems.) There are at least three hardware versions on the street: 1.00, 1.02, and 1.03. There may be more.

You can see the hardware version by running the firmware update software.
