Dont know if it would help, but could you reload the updates and see if it would fix your problem.

Many of the issues with SS on the DNA 200 have been resolved with the latest firmware. All I run is SS316L on DNA 200 & DNA 75’s and love it. There are better wire’s for TC but SS is the least expensive and most readily available.
SS has a low TCR so, it’s taking the mod manufacturers awhile to perfect. Not quite there but Evolv has come a long way and I suspect, done a much better job than other manufacturers.
Don’t give up on SS, yet!
Yes, Evolv has made some serious advancements in their boards for SS. I got some 316L early on in my TC adventures, but after hearing from another ELR member who I trust, switched to Titanium…specifically 22ga. That’s what I love most. But recently I got a few SMOK TF-RTA G4s and rather than “try” to make a smaller gauge Ti wire work in a quad coil setup I went with what I knew would work resistance wise, and that’s 26ga SS. I wouldn’t vape dual 26ga SS but in a quad…it’s splendid!
I like titanium as well except for cleaning. With SS I just dry fire the gunk off when re-wicking. Can’t really do this with Ti. How are you handling this? Are you regularly rebuilding or?

Sorry for the late reply. I didn’t see this till now.
When I run my Ti builds for a long time. Between builds when cleaning is needed I’ll switch the mod to power mode and pulse fire using 40-50 watts or if they are really gunked I’ll drop the power to 20ish and hold fire, making sure not to get them glowing. This typically will burn off the carbon without developing much TiO2. Then I use a nylon brush attachment on my Dremel to clean off the burnt carbon. Last few times though, after dry burning I just used a toothbrush and toothpaste that is fairly abrasive. Works quite well. I think it was @boyhowdy who found a method for cleaning Ti using just wick and water. Perhaps someone can guide you to that thread. I couldn’t find it.

I use a method similar to @SthrnMixer. I use a small SS welding brush to clean when doing a re-wick but when it is starting to get a higher Ohm reading I use the wet burning method. @BoDarc came up with the wick and water method of cleaning , it is described along with others in this thread.

Or you can always just rebuild. It’s not that much more work.

Yes…thanks bud! I couldn’t find it for some reason. You can thank me later for comparing you to Bo 
For me it’s not the work involved, it’s the lack of necessity. I’ve made Ti builds last more than 6 mos by cleaning. Helpful skills when the zombies take over

Wowzers, 6 months sounds nuts (but impressive)!
I’m probably gonna be surprised as heck when my spool of stainless eventually runs out, but I’ve rebuilding at least 1 coil per week since I switched to it, and I feel like I’ve barely put a dent in the spool.

It is crazy the length of time the Titanium coils will last if needed with just a little maintenance.The @Pro_Vapes deep water coil build has saved me tons of cash as that was what finally got me off of the factory replacement coils.
Not to derail the topic of SS as I get very good life from them as well. I have been using 316L claptons with great results when I can’t use a low ohm build.I am going to try and use @SthrnMixer method of rebuilding my Smok G4 decks this weekend.I must admit I am not looking forward to building on that deck!

I wish you best of luck. But if I can do it with my huge hands and terrible vision, I figure anyone can. Hint - install the bottom leg first. then the top. The top has a little lip next to the screw so make sure the wire is between the threads and that lip. Don’t stress too much trying to make the legs the perfect length. As long as you get the top and bottom legs in tightly, you can actually move the center point of the coil with your jig mandrel. Have fun!

I can’t seem to find the details now of your build for the G4.Could you repeat your build specs here please. I found the 26ga. but not sure of the inner diameter , number of wraps , contact or spaced ?
Thank you!
Sure brotha, pretty sure I did 7 wraps, contact (strummed not crimped). ID is 2.5mm. Should clock in right around 0.11 ohms.

If it weren’t for the need to clean the Ti BEFORE building with it, I would agree with you.
You should clean all wire before using it.

With my SS I just put a few drops of PGA on a bit of paper towel, pinch the towel with my fingers, and pull the wire thru a few times. It’s quick, gets any machine oils off, and straightens the wire a bit.

I clean all wire types before i build, no matter what the wire, period.

And it’s all dirty to one degree or another isn’t it?

It is brother. Straight off the factory floor it’s never going to be clean, so why take the chance of containments when a simple clean before use will suffice. No brainer.
I use ss 316l 22awg + 32awg clapton wire great flavour massive clouds I have also used 20awg ss 430 lovely wire to work with resistance is a bit low though maybe go for 22awg if you are gonna try it
