You need to input in what setting your mod is set to. Example Ni200 or Ti.

Hey guys been watching this thread and reading back for ss430 info.
I like the strength of the wire and it works good in tc in the evic vt in ti mode .... Most the time.
An issue I'm having is that it intermittently jumps out of tc, which isn't too bad cause it vapes great in VW mode too. Legs are tight coil is good. Spaced of course.
What happens is the vt stops reading resistance change for some reason for a while then starts reading again. Since I can watch the res change in VW mode I can see it.
For instance I had a .8, 28g 430 from unkmn. I vape it hot at 280-340f for crazy heat. When I test fire it the res will climb up to around 1.4. When I have an issue the mod will only read a static resistance of .8 in vw mode, or if I unscrew and rescrew while warm it will show higher like .9... If I monitor it, soon the res will start climbing again and I can go back to ti mode for quite a while.
It seems to happen about twice a day. More often it seems when I go somewhere, maybe colder outside temps?
I'm not sure if its the vt or the wire. I'm not sure how the wire can become static. I was thinking it was a glitch with the vt, caused by the wire. But it could be the wire.
Currently have a .73 in there that worked well half a day then a couple short periods of VW and then ti mode held the remainder

The wire is NiFe52. I am sorry to hear that some don't feel it is performing as expected. Your order has shipped. If you would like to return or exchange it I am happy to help you with that.Sincerely Ralph
So there it is, going to return it and hope all goes well and ask for refund. Anyway from this reply they still stand its nife52.

True, the Evic Vt60 doesn't like >1ohm coils but I'm also having the same issues with twisted 28g @.34ohms. The tcr of 430ss is probably too low for the mod to consistently read it as a tc wire.
This I know, but that doesn't seem to be the issue, because it will work fine for most a day when I know at the set temp its up towards 1.3x and it works fine.. The displaying resistance change in vw mode doesn't register when the issue crops up. The inconsistency is whats wierd. I'm sure my .8 ti builds have gone above an ohm during use.
Ok its wierd, only occasionally it jumps.. But taking what you said into consideration... My current .73 coil in VW seems to only climb to .98 most the time and a tad over one sometimes. Its been holding ti mode today.. Maybe if I get it down below .7 so it never goes above 1ohm I'll have better luck..
But cigtron said he also had the issue with a .3 twisted ss430.

The change seems pretty decent at higher ohms, but seems to reduce as the ohms go lower. .8 -1.1 , .73 -1.04 ohm on the coils I've tried.
There may be an ohm sweet spot for ss430 on the evic.

Seeing as the Evic won't show climbing res in tc mode you have to be in vw mode right? So depending on the wattage setting in vw mode your max res would change right?. It's based on heat/wattage so in order to see the most accurate depiction of max res in tc I do the following:
Vape in tc mode while looking in a mirror and note the wattage while tp is NOT engaging. (Basically set the wattage near to, but not at, tp engaging wattage) Then switch over to vw mode and set the wattage to what you set in tc mode while vaping. Then vape in vw mode while looking in a mirror again to see the max res.
That's the closest you can get really, besides doing tfr calculations based on tcr differentials between the vt in Ti mode and 430ss data sheets.
Fwiw, my twisted 430ss has stopped working in Ti mode altogether, it kicks me out immediately and won't show res change in vw mode until it cools off back to near base res. Two identical builds act the same.
Res change at 30w for my twisted is .34-.49 ohms while vaping in vw mode,,,, when it does decide to read res change.

Yes similar as you describe. I have it set so it vapes the same when it goes to VW, which is about 42-45w. When it holds in ti I can go VW and see res climb its only when it jumps that the res no longer climbs in VW mode. Once it starts climbing again I can go ti mode for hours.
Its only about 10-15% of the time that it refuses tc. That's what I find confusing. If ss doesn't work then why does it work most of the time in my case?
Edit*
Like it just jumped on me after probably 6 hrs or normal operation.. After a bit I was able to unscrew a few times and then it worked in ti again just fine.
What kind of thing would cause a static res reading? Not contacts I don't believe, its got to be an ocassional glitch with the software due to the wire.
Really I was posting here hoping some of the more seasoned temp control and wire folks, like @TheBloke, may shed some light. Or some theories.

Lol, we've already tried to figure something out in the vt thread. So were on the same page. 
Tried combing this thread but didnt come up with anything.. We seem to be the two that identified the actual event logs so to speak.

Yeah, I know "J". I hope some of the whizbang tc gurus here can help us with the Evic/430ss dilemma but I feel at this point we may just be trying to polish a turd.
I downloaded and emailed the Kanthal NiFe52 data sheet to Ralph a few days ago. While I did not include a question in the email, I've not gotten a response.
Are you guys dry firing your SS430 coils to a nice orange glow?
Personally I use a true VV mod to dry fire my SS coils. Contact coils will read very low until they are heated up and 'jiggled' or 'tweaked' a bit. When I say 'heated' I mean glowing red hot.
I've heard others get great results with twisted SS430 however I was having resistance issues that might be similar to what others are experiencing. My working theory at the time was different parts of the twisted wire was shorting/unshorting causing the resistance to jump between fully twisted "resistance read as a ~26-27AWG wire" to a single 28AWG wire. (since it is difficult to say if BOTH twisted strands are making contact with both screw points) I've mostly given up on twisted applications as a single contact coil works fine for me - as long as I get it glowing good from the center out.
Yes, both Jeremy and I are firing the coils to oxidation temps. Afaik Jeremy's last attempt was a straight forward single strand spaced coil in an attempt to remove all possibility of shorted turns but I could be wrong on that, he winds a lot of coils. My twisted coils were preannealled before twisting, then fired to complete the oxidation, actually firing perfect on first pulse.
Thing is, neither of us seem to be having probs with intial build res changing while using 430ss, just that our Evics are having trouble following the low tcr of 430ss imo. The Evics were never designed to handle anything but Ni and Ti in tc and sometimes sees the 430ss as non-tc wire thereby jumping out of tc mode into vw mode, but that's when things get really weird, at that point our evics will no longer display res change during firing. Some finagling by cycling power or modes or resetting base res does bring back proper functionality eventually but for my rigs it's short lived; Jeremy's rig seems to work for longer time periods before the malfunction reoccurs but I suspect that is due to his res being higher than mine ( .7-.8 vs. .35) and therefore has a higher percentage of active res vs.static res, perhaps aiding in the mods' ability to read res change . It's the only thing that makes sense to me so far.

so the big reason to switch from Ti to a nife is mainly contact coils and the ability to dry burn like kanthal? im just wondering if i should start lookin for some and retire my ti like what i did with nickle. i cant remember my last ni200 coil build, except for premade ones for my crown. those of you that are using a nife alloy, are happy with it? more so than ti? equally good? etc.
@AtmizrOpin Yes, I now have four attys built with NeFi 52 (Zivipf 48). It is a bit premature to declare it the final replacement for Ni 200 but I am headed in that direction.
Once my 24 awg arrives I believe I can be definitive, hoping to bring my cold ohms down--a lot-- in the range of Ni 200.
I was never a fan of Ti because of the risk TiO2 (valid or not).
Welcome to the club and please let us know your experience, good or bad.

kool, which should i get from zivipf? im seeing the 30 has a higher tcr than the 48. im a 26 awg type of dude. im gonna get a spool of each, 26 awg nife30 and nife48. how long is shipping from there to the US?
