I have an MFeng UX that have temp control built into it and I have a crown iv tank that has stainless steel coils with it out of the box. I tried the tank on an IStixking 530 mod with coil set to stainless, I tried a tcr of 0.000093(I think?) And kept the temp below 400. The Sticking said no juice detected, I looked it up, some people were able to use nickel and it work good. The coil died fast, and I wanna learn how to use temp control without ruining the other coil. Basically, I wanna use it on my mfeng, and not guess at what settings lol. Any advice?
