No it's actually not a common problem.

If you're in the right mode and everything is clean, then my first guess is a connection issue.
Either in the atty's 510 stem or loose post screws or holdowns. If the res jumps around, the mod gets cranky and kicks out of TC.

The other immediate possibility is accidentally using non-TC wire. Again... cranky mod.
Ok I'll probably recoil and double check post holes and give it a shot but just wondering if I should be using TCR or ss316 mode? And what TCR code if that's the mode I want? Thanks for input!

As Backseated1 asked earlier, it might help if you state what mod and atty/tank you're using. People who own them may a better idea where the potential problem points are.

As 2legs posted last night, the 3.03 update seems to have modified the algorithm for the better.

I've had some builds on a mem slot in the 120s, some lower, and others using the stock SS mode (3.01 and earlier) so it depends on several factors, some hardware and some personal preference.

The hardware variations shouldn't exist... but they do. Play with it, see what works for you.

I disagree on both counts.

0.7 is not only not even remotely low for TC... it's just about spot on for 316 SS, IMO.
That's quite high actually, a lot of us are still adjusting our builds up towards that... for that greater res rise you cite.

And while you may feel you've read accounts of the issue a great deal, it actually comes up quite seldom proportional to the totality of posts on TC.
And those are most frequently not the mod but user error... often the two I mentioned.

However long it's been since last summer... I've used mostly TC, mostly 316 SS and eight or nine various maker's TC mods and I can't make them kick out.
It happens, but it's usually an easy and quick fix... or it's my xCube being a pillock... again. :p

I didn't say this issue was due to low ohms, I'm saying this issue usually happens when the ohms are low.

I'm not basing my observations on ECF alone. I have read a hundred or so reports of this happening in various places, it's generally stainless steel and usually of the 316 variant.

You are certainly free to disagree, I take no issue with doing so.

Hey guys, trying to find the best build for SS 316L temp control that'll give me decent battery life. I've got 26G MKV 316L from Fasttech and I'm building it in the Griffin. I've tried a 10 wrap on a 3mm bit (0.36), and a 10 wrap on 3mm (0.22). Both want to push at least 60-70 watts constantly.

I'm also having difficulty in general with SS TC. After building a coil temps are super hot, but the next day (I usually build in the evening), I need to ramp up the temp (from 350-380 to 420-450) to get the same experience. Is the coil settling or something? I'm using the SS316 mode, because I can't get anything decent out of TCR (from 88 to 102).

The best experience I've gotten so far was a 9 or 10 wrap single coil in the Stumpy RDA, but I'd like something similar in either my Griffin, Crius or Subtank Mini RBA.

I wouldn't rule out a wicking or tank pressure issue. I have almost the same setup. VTV Mini, Griffin tank, SS304 dual coil at .35ohms and notice the same thing.

After filling the tank the vape is warm, because liquid is in the chamber from pressure of screwing on the cap. Later the vape is much cooler... Clouds but no warmth. BUT if I loosen the cap and let a couple bubbles surface, then the vape is immediately warm and full again.

It seems that when the tank is down to 3/4 full or so, the situation improves, maybe something to do with tank pressure, I don't know.

I'm having good luck with TCR (105 is standard for SS304) and I have not yet upgraded to 3.03.

I'm looking for a solution, and plan to try filling the tank only partially full next time to make sure that helps. I just today figured out the connection between tank fullness and the vape warmth.

I've previously been trying various wicking techniques, but since opening the fill cap "fixes" the vape, I'm not sure now that wicking is the issue, as long as you wick the Griffin with just a bit of wick under the ring, as is the recommendation of most Griffin owners.

I hope this helps, and would be interested in any ideas you or others have about solving the problem. Cheers.

Well I may have been wrong about the 3.03 update. I tried SS316 mode and it is like it is kicking into Power for a while so I tried 0092 like Daniel said would work and I had to go to 500F for a decent vape so I went back to what he said to use before the update which is 0108 and I'm getting a nice vape at 450F. I have a .45ohm build in it SS316L. In TCR mode no kicking into wattage. I know it's not my build because I'm using the same one on 4 SX's with the same atty's STM's at TCR 00092 and they all work perfectly as this one does on the SX with the same setting. I thought maybe I messed up the FW so I rolled it back to 3.00 and then upgraded to 3.03 still the same. Definately use TCR mode like I say 108 seems to be pretty good none of that hot vape like I got in SS mode even at 390F. It's nice and smooth at 450F it's still not as good as my SX's at TCR 92 420F.

No problem. I expect someone got excited because a build changed performance and it was a game of Telephone from there on out. I've used 316 builds in everything from the stock mode to 128.

I don't expect SX/DNA accuracy from these $30 mods. And I appreciate that the JTech feature set gives me multiple options to adjust it how I like.

Thanks for the update.

JT put out a poll on their firmware functions. It might be used to adjust a future firmware so if anyone wanted to ask something of them now they should have your attention. They also have something about jumping out of temp mode in there. Joyetech Upgrade Firmware Poll

Thanks, and a luke warm thanks to JTech for at least having a poll.

But very few users join MFG forums... the poll has been up for two weeks and the thread is all of 17 posts long and only a dozen or so respondents to the poll.

If you want to hide the suggestion box... they sure figured out how. :rolleyes:

And sad to say... it's an utterly crap poll. Utterly.
Though I did learn that Flappy VTC isn't terribly popular. No real surprise there. :p

Totally agree! I'd simply like them to publish the TCR's they are using for the PRESETS. Especially the SS preset, does not align with the known TCR of SS 316.

I tried to use these 3 tcr modes as profiles for an SS304 coil with different power/temp settings on each but the changes I make in one mode sets those settings in the other two tcr modes. I'm guessing this happens because there are the same tcr values set in all modes. Running FW 3.01. Can anyone confirm it's fixed on later updates?

Sorry but... the mem slots allow you three custom TCR values... but the Temp and Power selection carries over across all TC modes.

That applies if you have let's say 3 different atties coiled with 3 different TC metals having set their respective different tcr values as well? I guess so. That's what comes across from your post. That's fine. I didn't even try this until now because I was lazy. I saw someone's post over to the MFG forum that that's what he does and that's what made me try it. Even it did work it should've been implemented better to allow to switch between a couple of different pre-set power and temp settings as fast as possible on the coil installed.
