I agree TC is inaccurate.... regardless of material....
Is why I prefer VW or VV regulation using a curved power profile.

I used to doubt TC on proper wire until I really spent the time fiddling with it. I don't want to go back to VV VW.

Accuracy is debatable. The science and math behind TCR/TFR is not, as long as you stay within acceptable parameters.

If I set my temp to 350F, I don't expect it to be spot on 350F, but what I do expect and get is a consistent vape and no dry hits. Outside in the cold, it works... not paying attention to dry wick, it works.

It's made my vaping experience substantially better.

With TC I can breathe vapour with any power, also I can just press fire and don't vape it - cotton will not burn. You cant do it with VW

Kanthal does change resistance when heating and cooling...... but the change is so slight most TC devices are not sensitive enough to regulate it.

Some TC devices can detect the differences and are able to TC with both kanthal and nichrome.

You're talking about the Hohm tech devices, right? I don't think they tc kanthal and nichrome by reading changes in the resistance. The information they provide is very confusing though so it's difficult to understand what exactly the chip is doing.

I tried this once and was not a fan of the stock SS TC profiles but I think I need to throw it back on to one of my wismec's now that I have 3 in rotation and give it another/proper try with some tweaked TC profiles. Can TC profiles be exported/shared? Anyone have any preferred settings/profiles for SS316 in the 0.1 - 0.2 ohm range? I normally vape in the 75w - 125w x 400f - 470f range on my wismec and hohm tech g2's

Well I have been trying to get TC to give consistent vape for about 6 months now........ most scotched and hot hits I've had since I first started building coils using protank heads. Yeah tc doesn't burn the wick. But the random hot hits
and non hits just drive me nuts....

Sure it could be my mod..... but from what I've seen... that's not purely the case.

Could be like the rest of vaping. What works for one... may not work for all or anyone else.

Just recently i've decided to do a cotton burn test before every rewicking to see if the coil is behaving consistantly day to day. that's means doing the test with a clean coil so gunk isn't creating the appearance. It's also possible that an affordable infrared temp sensor could be configured to take an accurate measurement but it would have to focus on a square mm or two. Seeing the temp and watts for each puff has been a revelation, helping me get a better vape. Most of my puffs are at a lower temp or less watts than I thought.

I wouldn't be surprised to learn that TC works best on Ni200 wire. Ever see the difference in the TCR profiles? I'm surprised SS316 is even supported for TC with how little the resistance changes over the temp range.

Yes, but thanks the chip it works fine! Building coils with Ni is a true pita for me! I hate ultrathin wires...

I'm using 30 guage stainless at the moment and rewick twice a week. I've decided to do a cotton burn test at 420 at every rewicking to see if temp acccuracy is holding. Just did the second test, it was the same as the previous test, so far so good.

Yeah, also AF has TFR (not linear temperature coefficient).

You should understand how TC works.

For example, SS change it's resistance about 10%/100°C
200°C is «best» target temperature but...

As I know, NiCr change resistance about 1%/100°

If you want your device feel difference, you should use bigger resistance.

For example, device can feel 1ohm→1.01 ohm (it's +100°C) or 1.02 Ohm, so accuracy will be better if 0.1→0.0101 Ohm

It works on SS to. Bigger Ohmage → better accuracy.

Also, sometimes start resistance value can be not be real, if wire will hot and with some other reasons.

If start value will be too low (for example, 0.4 ohm instead 0.5), +10% = 0.04ohm, when device get 0.044=100°C, 0.48≈200°C
If start value will be too high, like 0.6 ohm and you set 200°C, target value will be around 0.72ohm. If real resistance=0.5ohm, 0.72 equalent 0.5+0.05*4 — it's 400°C

(you should know that normal condition is 20°C, I ignore that, but device still believe that you set you coil in 20°C)

In AF you can correct resistance manually profile→coil resistance→short Fire→±, or refresh resistance in profile→coil resistance→long Fire
Or edit screen/resistance(not «real»)/long Fire

As for me, I do so: just see which temperature it shows when I have enough vapor and set that temperature (I can correct). Now, I vape on «fake» 175°C and don't worry about that

In real case error range about 0.1 ohm is not very really, except your coil is twisted badly and some other error, but 0.0xx range is quite real. AF can show and correct 0.00x. If you have coil like 0.10 SS any range will affect on showed temperature. Original firmware in that case can drop you to the VW mode, but in AF you can disable it.
So, comfortable values can be around 110°C, who cares, if it works ?

The resistance of ss316 is far higher than of ni200 though, and that matters too. While the resistance increase of ni200 is relatively higher, the actual resistance increase of ss316 is higher. The tiniest bit of resistance reading error will make a major difference with such a low resistance wire as ni200. Looking at steam-engine.org a 28ga 2 mm id 8 wrap ss316 coil has a higher "tc accuracy" than a similar size ni200 coil. A comparable ti01 coil will have a far higher tc accuracy than either.

Works on my laptop just fine.....

Did have a USB recognition issues.. but hard reset of the mod to factory install fixed. Have switch back and forth eleaf vs AF several times since. My issue may have been caused by the cable.

Does anyone know if the PI regulation setting do anything for the Pico? Settings?

Very interesting. I had not considered the base resistance of the wire as factoring much into the TC accuracy, rather I only considered the resistance change per degree. I must look into this...

Just tune your °C/F for yourself and don't worry a lot. As for me, I don't use not linear TFR, coz I don't need «real» temp. Now I created «TCR 50» (instead stock SS 316 ~94) and set fake 275°C. It works fine and should have better accuracy

Is there anyplace where preheat for temp control is well documented? My goal is to get a satisfying vape at the lowest max watts that physics and my skills allows. At the moment thats 15 watts (preheat watts mode) with 30 guage wire. I've just stuck my toe in the water with preheat. I cautiously made a 3/10 second pre heat at 17 degrees to see if I could tell the difference--may be. Besides using less power I also notice my 30 watts vape slightly irritates my mouth and throat. I'm looking to put a stop to that. I'm learning i can still get a throat hit at the lower power if I draw a bit slower, meaning mix less are with the smaller amount of vapor being produced. I've only been using the 30 guage and lower power since Saturday and there seems to be less irritation.

Plug into PC and use the device monitor to watch what happens when you tweak preheat.

I set mine to relative, 220%, .4 seconds. Normally power is around 11.5W. The preheat pops the temp right up to my set point and I find it a much better vape.
