Temperature Control On Rda Clone

I've got another one of my most likely idiotic middle of the night burning questions. On my mods that have temperature control they usually will have all the usual Metals you know stainless steel nichrome titanium but then they'll also have an option just called TCR or called temperature control TCR. Can someone explain the difference to me like what exactly is TCR compared to temperature control and choosing which metal you're using?  

Temperature control testing results are available for the DiCoDes Dani 25 using the stock SS profile, he imgur.com/a/89GNaPJ

Temperature Control Testing Results: DiCoDes Dani25 tube mod (~$300 USD) : electronic_cigarette

TLDR: This is a $400 AUD mod that doesnt produce a premium temperature control experience in many states. The method of temperature control this mod uses produces a wavy temperature experience you can both hear and feel in most cases. Like PWM, it creates a band of temperature outcomes from pulsing more power than it needs to keep the coil temperature maintained. It mostly succeeds at providing dry hit protection, but unless you are using high resistance high or high mass builds, there are smoother and more accurate outcomes on a range of cheaper mod. The TCR value can only be set in 5C steps so that makes it impossible to dial in but fortunately the built in SS mode (TCR92) is reasonably accurate and consistent on average. Overall the default SS setting is slightly under the set temperature. Between the premium priced boards, both DNA and YiHi methods produce a better temperature control outcome than this DiCoDes board in terms of smoothness, accuracy and range around the set temperature (I think objectively?). If someone wants to lend me a different DiCoDes to test, I will pay for shipping and be very careful with it.  

Temperature control testing results for the YiHi Sx Mini G Class are now available here and there are some particularly interesting issues to discuss imho: imgur.com/a/os23png

TLDR: This is an unusual one. You can get a sense from these charts of where the YiHi SxMini G Class got its reputation for being fast, accurate and smooth in temperature control mode, especially for when it came out a few years ago. But this mod created a range of challenges for our testing methodology and rig because of the pulsed (PWM) approach it takes to temperature control. What we do know for sure is that it does dry hit protection, and the temperature outcome falls within within a fairly narrow range that averages out to a fairly accurate and flat result, if a smidge too hot in most cases. But if what we are seeing is real, there may be a key difference that arises with this kind of temperature control method, where high fixed high power pulses produce rapid, tight, almost sawtooth changes in temperature in a narrow band. This is happening so fast it cannot be perceived in most states. This may be the basis for some of the subjective preferences for YiHi/PMW mods I have heard, such as it feeling "punchier" and producing better flavour (possibly from higher temperatures being reached which may have implications for those seeking to avoid thermal decomposition of their juice). Some insights may be drawn from the oscilloscope image at the end  

I just discovered that my Hcigar VT Inbox has a temperature control setting. Question is why. Is this why I haven’t been sleeping good at night. Why my clothes don’t fit right. Why I don’t know the answer to all the questions. (Being sarcastic).
Really though, curious minds want to know.  

Apologies for the reddit links, but imgur links turn into blank black boxes for some reason.
We have been undertaking a consistent set of tests to produce graphs of temperature and power behaviour of various mods in temperature control mode to work out which mods do what they say on the box. See list that follows. DiCoDes and Vsticking will be released in the next week or two.

The results are in for the Smok Mag for SS temmperature control testing, and if you set the TCR to 75, you actually get a pretty damn good result. Full charts, analysis and conclusions he

So I was wondering if there is any correlation between throat hit and temperature. I noticed that I feel a larger throat hit or end up having a sore throat when I use my tank throughout the day, but I don't when I just use my RBA and the same juice. So does a cooler vape lead to a stronger throat hit?

For reference, the tank (Lemo V1) is built somewhere between 0.4 - 0.6ohms (24g single coil) and the RBA (Doge Clone) is around 0.2ohms (24g dual coil). All coils are 2mm inner diameter and cotton wicked, but as would be expected, airflow is significantly larger on the RBA, but the vapor temperature feels to be warmer.  

Temperature Control Testing results for the DNA 75C board (Lostvape Paranormal) using the Steam Engine SS316L profile are available he

TLDR: You might expect that the DNA75C results would be better than the DNA75 (original) results, and while the results are largely comparable in most states, there is some overheating and more volatility compared to the classic DNA 75 under the same conditions, shown here imgur.com/a/7Pe3Gad. However, under the "new" test using a dual coil high mass low to mid resistance build, the result was one of the best I have ever seen for any state on any mod in terms of accuracy and flatness (but I have no prior results for this test to comapare to). Using the stock SS316L profile or DJAquith 3.5 did not produce better results. You can see the results using the DjAquith 3.5 results, he imgur.com/a/Abf57Fi. The Steam Engine 316L profile was still the most accurate according to this rig/analysis and as best as I could tell from my thermocouple.  

So I'm looking into buying a temp controlled mod for my next purchase. Ideally, I would be getting the VaporFlask with the DNA40 board. Problem is, I dont have $300 usd to drop on it. Sooo....

I was thinking about the FT clone, and was about 3 clicks away from making the purchase when a friend tells me about the IPV4 pre-order over on the bay. The DNA40 has temp control and goes up to 40 watts (duh) but from what I have read, the IPV4 also has temp control and goes up to 100 watts. I'll never use all 100 watts BUT sometimes will vape above 40 watts. I like that both are dual 18650 and have the temp control function (I'm dying to play with some nickel wire) I'd really like some opinions

Any thoughts on the VaporFlask clones from FT? Would it be worth it for me to wait for the IPV4?

Cheers ECF!

Eleaft iStick Pico 75 - TC bang for buck that is remarkable - Temperature Control Testing ResultsArctic Fox Firmware 190624 Stock SS316 Profile : Vaping

The attached is the first of 7 charts/states tested and does not represent overall performance - see IMGUR or Reddit for full report and analysis, or the TLDR summary. See a full list of mods tested so far, at the bottom of the full post for comparison.

TLDR: I bought this little mod for merely $15 bucks in a sale, and yet other than one (repeatedly tested) very different outcome for a (rarely realistic) completely dry MTL coil, it performs very well as a temperature control device, with good power (unless youre a very high mass dual coil vaper, in which case you need a dual cell mod), tight and accurate temperature control that is arguably largely comparable to DNA in most states (see imgur.com/a/EOL9hRE for current DNA series comparison). Its hard to beat in terms of price for performance...lets see how the stock firmware compares in an upcoming test. This Arctic Fox firmware provides a lot of the functionality of a DNA device, its free, and its compatible with a lot of Eleaf, Wismec and Joyetech mods! More testing required to see if it holds up across that range.
