Crown Tank with HCigar VT200 question

[Stevens8693]

Does anyone use VT200 with a Crown tank and have weird resistance spikes? Right now I have the 0.50 SS coil and resting at room temp it reads "0.55" not too off. When I use it it will jump around anywhere from 0.53 - 0.67. Kind of sketchy.
I've tried taking the tank apart and reassembling and making sure the coil is tight.
The 0.25 are more accurate, never had one go over 0.30.

The resistance of stainless steel raises as the temp increases.

I do own a vt200 - I have some 316l ss on order - I believe you have to lock the ohms & make sure you have the proper profile for stainless selected in your mod - also make sure you update your vt200 - evolve has included new Ti-1 and Ss profiles for the new firmware - also a good source to check out the evolve Dna200 early adopters forum - hope this helps

In fact, Evolv advises against locking the resistance. As the poster before you says, stainless steel (as the Crown coils) and k other tc materials increase in resistance as their temperature increases. Reading that increase is how tc mods determine the temperature of the wire.

I have updated the VT200 and have it on SS mode. I don't run it in TC because I get a weaker hit and muted flavor.
I also read somewhere on the DNA 200 forum that these coils have legs made out of nickel. Not sure how accurate that is but that might explain the weirdness I get from running them in TC mode.

On my Herakles V2 the resistance stays solid with the SS coil.
This is my second Crown tank and the first one was exactly the same.
I do have the V1 VT200 with the Brass 510 connection. I know they upgraded it to SS in the V2. Plus, sometimes I get a "Check Atomizer" message with new crown coils or new Rafale coils with my Rafale tank.

Oh and with my TFV4 I can't screw the coil down all the way if the chimney is screwed all the way in the coil. So it's either screw the chimney down all the way and get a "Check Atomizer" message or screw the coil down all the way in the base and have the chimney a little loose and get leaks. Unless I'm using the Clapton coils. Those work fine. But I think I have an issue with the 510 connection.

If you have it in see more mode you are running it in tc.

So I should use the default material setting even though it's not Kanthal?
That was kind of dumb of them to do considering SS has a different temp curve.

You don't need tcr curves unless you're using tc. Vw doesn't care about that.

So I've been running in TC mode on the SS setting but I have to run it at 600F to get a Vape at 65 watts. If I had the .25 coils in I wouldn't be able to run TC mode because there's no flavor until about 70 watts and I always run it at 80 with those coils. Just my pref. You think that temp is okay/safe? I read that with SS you wanna run it about 100F higher than nickel. I would think with the SS TC mode it would correct the temp readout so I wouldn't have to do that. Maybe it is bit like I said I don't get anything out of running it at my normal 470-500F nickel range.
Thanks for help!
