yeah its off by a % not linear, so if its off by .4 ohms at 1 ohm, it would be by .8 ohms at 2 ohms

the % of the resistance when using TI on a mod thats meant for NI wire, meaning the higher resistance you build the farther you need to reduce the temp to get it to work
thats true, but that isnt waht you were saying anyway. I took it that you were saying that the temop offset using NiFe48 on a DNA40 would be less at lower resting resistance than at higher res...That isnt true! Or maybe thats not what you meant..
it most certainly is, i have to reduce by about 110 F on my sigelei 150 TC when i make higher resistance TI coils, other wise it will burn the cotton

well I guess it depends on what you like in a vape but Im not sure that many would support your contention that the subtank mini is the best rebuildable device available! I certainly dont although, as I did say, its a great RTA for the price and for what it does
I'm always trying to find a new tank I like more. They all seem to have some flaw that annoyed me so I stopped using them. I'm giving the rage tank a try and so far I'm not too impressed it seems to mute the flavor.
im not saying its hands down the best out there, that would be dumb of me, what i mean is for me and the way i like to vape, compared to what i've owned, it is the best for mewell I guess it depends on what you like in a vape but Im not sure that many would support your contention that the subtank mini is the best rebuildable device available! I certainly dont although, as I did say, its a great RTA for the price and for what it does
That may be true but there should be no difference. You can even check it in Steam Engine if you like using the wire wizard!Basically if you were correct, that would mean that the TCR value changes dependening on the starting resistance which is nonsense. The effect you are seeing is probably a limitation of the mod...
what i mean is TC mods use an increase in resistance to guess temp, you make a NI coil at .05 ohms, and the chip expects to see an increase in resistance of a % of that number, and then you make a coil at .25 ohms from NI200 and the chip will expect the same % increase, lets just say its 25% for arguments sake, so the .05 ohm would see an increase of .0125 ohms, and the .25 ohm would see an increase of .0625, but TI doesnt work with the same % increase as it goes up as it heats,lets say TI has an increase of 32%, means that the higher resistance the TI coil is teh bigger the gap gets in real resistance even though both %'s are respectivly the same
are you using a dna 200 device? great board for experiments.
no im not, with christmas looming in the near future and being a parent of 3 the budget wont allow me to own one till the new year
I wouldn't call it a guess.
It is a quite straightforward calculation:
If you solve this equation for resistance change in % you would get this:
(R(T)/R(0) -1)*100=α*(T-T(0))*100= resistance change in %, where α=TCR and it is not initial resistance dependent
bottom line:
you set your target temperature for a given initial resistance and the mod will calculate your target resistance.
And it doesn't matter how big your initial resistance is as long as the target resistance is within the limitation of the mod
However, what does matter is your target temperature.
Ni has a significantly non linear TCR curve and its TCR is increasing by temp, meanwhile Tis TCR is almost constant.
Means, the higher your target temp is the bigger temp offset you need to use a DNA40 with Ti.
With a DNA200 or a device with manual TCR settings is not an issue though.
didnt have the equation, but it supports what i said, although i may have explained in a way that emphasized initial resistance, i was talking about targetI wouldn't call it a guess.

(R(T)/R(0) -1)*100=1+α*(T-T(0)= resistance change in %, where α=TCR and it is not initial resistance dependent

No, it doesn't support.
Should the Ni has constant TCR (as most of the Chinese board thinks) for any other flat TCR wire there would be a constant difference between the displayed and actual temperature regardless of the initial resistance.
