First time i have found TC not to my liking DNA200/Uwell

[Deleted]

Bit of a strange one, using the stock SS coils in the Uwell Crown on both my DNA200's and the vape imo is pants compared to just running in normal mode. Downloaded various tcr's from Steam Engine ( 304 and 316) And whilst there was a difference between the two,  the vape was just a sort of watered down version of running the same coils as normal . 
Also whilst running them with the SS tcr's the temp had to be  right up at the 580-600f to get a decent vape without the coil being cut aggressively.  

In normal mode the flavour is the best yet that i have got from any tank, nearly on par with my drippers, maybe i am missing something, i have read there was some question on the Crown coils having Ni200 legs, but cannot find any further info confirming or denying the info. 

Also pretty disappointed with the performance of the Ni200 coils, They work, but yet again the fkavour just goes, even at low wattages.Now i could see this possibly being an issue on one device, but this is happening exactly the same on both the HCigar and Efusion, i can only think the tcr's are way out, or Uwell are using some strange alloys or something.

When you say "normal mode", do you just mean wattage mode with the SS coils? If so, what watts give you the "best" vape?

If it's working great in wattage mode and poor in TC, then it's not getting enough (or I suppose too much) power to the coils.

I'm not an expert on Escribe, but could you see the watts on the graph in TC mode when it's poor, then compare with the graph on Escribe in wattage mode & the vapes good. That might give you a clue.

I remember reading that the ss coils have Ni legs which throws temp sensing out, sorry don't have a link there it was a in a DNA200 thread on PotV IIRC.

Wattage mode 40-46w fantastic flavour and lovely smooth vape. Using either of the tcr's for SS 30w and i am constantly bouncing off temp limiting, slight difference between both 316 tcr and 304. Also as mentioned above temp has to be raised way up 560-580 using the SS tcr's.

Gonna see if any other of my mods are usable with the SS coils , i have a feeling its to do with whatever these coils contain,are made of. 

Cheers folks

Cheers VB, ill need to do a bit of digging, i do think its down to the coil material as theres even a difference between my own coil builds ( Ni200) which work well, and the Crown Ni200 coil, which so far has performed pretty poorly.

SS is always going to be the most problematic as the electrical properties are not part of the specs they vary within grades and the TCR is so low anyway. Higher resistance coils will be easier to detect temp with and you will probably have to adjust to taste unless you get the TCR/TFR that properly matches the wire.

Ti is a better bet, the TCR is lower that Ni, but the higher res almost offsets that, but it is an alloy and the electrical properties are not part of the specs so again you need to get the TCR/TFR that properly matches the wire, but that seems easier than for ss.

Cheers for the info, i will likely just run them in wattage mode then but good to get an explanation. 

Thanks

It can be done with ss, but you just need more luck or more trial and error and in the end it is not as sensitive as Ni or Ti. For coils building NiFe30 would be a better bet fro DNA200 IMO, not any help for coil heads.

Oh dear - another wire to try I still find Ni200 a bit dry & cool compared to Kanthal. I have some Ti, but haven't got around to trying it yet. Will have a look at the NiFe30

Similar to the vape i like reefcat, time to give NiFe30 a try, cheers VapingBad
