Koopor Plus SS temp control help

[guyakaguy]

I just got my first TC mod - the Koopor Plus, and am having some difficulty with setting up the TC with the SS coils I have.

The initial SS coefficient, which was 0.00105, I feel didn't read the temp very accurately. I put my Crown tank with a .25 coil on, set the initial coil resistance, set the temp to 300f, set the strength to normal, and fired it. The highest I saw the temp go was less than 200f. I tinkered with lowering the coefficient to 0.00100 with similar results. I then read on a Reddit post the people were using 0.00094 as a coefficient with success so I set it to that; about the same thing. At 0.00094 it would pretty much only temp protect if I set it as low as it goes, which is 200f.

I then read that people were having success with their coefficient set at 0.00075 so I set it there. I can now get it to temp protect at 240f at normal strength, but if I set it higher it doesn't do anything. The highest temperature I've gotten in 'norm' has been 244f.

I just set it to 'hard' with coefficients between 0.00060 and 0.00120 and can get it to temp protect at 230-240f, but I still get the feeling that something isn't right.

At the 'hard' strength I get a pretty hot vape, but still get temperatures between 160-200f at the end of my 4-5s long puff.

I realize that there are several things I don't understand about this, and that TC is a whole different beast than power, but nobody has a "this is the coefficient I use and that works with my Koopor Plus when I use SS coils".

Either that or I need to get some other TC material coils...

Any recommendations

you sure those are not NI coils?

 

[guyakaguy]

Positive. Well, they say they're .25 SS on the package.

I wish I had some non-SS (Ni or Ti) to try out and see what the deal is. Maybe I'll throw another SS coil in, break it in and see what happens.

Someone who owns one will chime in, but I believe the Crown SS coils have Nickel legs. I read that somewhere with people having issues with TC. Almost certain that's what I read, and it's what's made me not try a Crown yet. If there's Ni200 on the legs, that will throw off the TC. My understanding is that SS has a ways to go for TC from my reading. I'm still yet to try it.

I'm really thinking it's those nickel legs, assuming I'm remembering correctly.

The deal is that Crown uses 316 Stainless steel it is not very accurate most of the other companies use 304 which works much better with TC you will always have issues with 316 even on a DNA 200 its hit and miss the TCR is to linear

Am I not seeing thing clearly or missing someyhing here? But I can't seem to see anywhere in the two pictures you posted that said SS coils. It just said dual coils on the ticked box, and the second part (not ticked) said Ni200.

The Uwell Crown coils that aren't Ni200 are all stainless steel.

Kanthal doesn't change resistance as it's heated enough for current mods to monitor, much less control or limit, the temperature.

I'm getting variance because it's taking a reading that goes up as it's fired, but just not enough for it to accurately read or limit the temperature.

Of course I could always just leave the coefficient at 0.00095 and the temp at 210-230f and vape it that way knowing it's probably easily 180-200f off.

I think I figured out how to get the Plus's TC to work with the Crown SS coils, for the most part. It's not perfect, but it's been working.

I set the initial coil resistance on the mod as low as it would go. It's the .25 coil (it's new, by the way) that was reading at .29 ohms and I set the initial resistance to .249 (the lowest it would let me for this coil). I then set the coefficient to .00075, after playing around between .00075 and .00120.

I'm getting it to temp protect up to 360f, but I haven't gone much further than that. I put it at 400f a couple times and the highest I've seen on the readout is 376f, but I'm also vaping outside and sucking 32 degree air through the tank. I don't know if that'll affect the temp reading or not, but it seems to be working now.

I'll keep playing with it, but I also have some Ni200 coils coming.

without knowing the correct coefficient, the temp displayed isn't going to be right

any change to the coefficent will affect how the temp is calculated

at least that's how I understand it

This is correct, but, as we discussed before, the Crown's SS coils have nickel legs. You'd have to know the exact length and diameter of each of the 316 SS portions, as well as the length and diameter of the Ni200 portions, then take the coefficients of each and make a ballpark estimate of the correct coefficient for the temperature you want.

In the end you're not doing much better than making a "sort of educated" guess.

It'll take more playing with, but I have to be fairly close.

If I hold the fire button at normal strength, which starts around 90w and tapers off I should be hitting 400f+.

I just changed the coefficient to .00065 and it's running up to 440f now. I set the temp at 420f and it's protecting at my "420". It may not actually be 420, and not having any way to verify the actual temperature I couldn't say whether it's hitting 420, or even 440+, or not.

What I can say is that if I set it at 400f and chain-vape it the tank and vapor doesn't get anywhere near as warm as it did vaping power mode at 48w.

The Crown SS coils are TC vapeable, but not at the standard preloaded SS coefficient.
