Use stainless or titanium grade 1Well...I'm too lazy/stupid to use TC. (And I've not yet seen convincing evidence that nickle [which is a carcinogen] does not leech into the ejuice.)
So I bought the VTC Mini as a "VW Mod"...based on its size, big screen, replaceable 18650 and upgradable firmware.
To me...$28.89 is not "overpriced"...

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.Well I am back to report that the mini reading .11Ω provided the useless anemic vape we have been finding all along...
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!
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.
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.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..
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.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.
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.
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.anyone knows how to fix the "Protection" problem yet?lol
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.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.

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.
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.Good Sir,

Thanks Jesse, I wasn't aware of that.Understood. Just so you know some people are having the problem with the stock or clr heads as well.
Well that doesn't bode well... I was hoping a higher resistance Ti build was the solution.so i reduced my dual coil to give me a 0.24 reading
as i i have guessed still having the same issues,,,
