@gadget That is different. Reminds me a little of my Yihi mods. When I put on a new atty they will give me an error message basically stating the atty is unacceptable. I don't remember the exact verbiage. I found a thread that recommended forcing a new resistance read. That works every time. One thing that seems to be universal in this industry is that a lot is left for the user to discover, lol. Really glad you found that. I am very interested in watching Hohm and seeing how their technology effects the market. I would love to take advantage of the added resistance of Kanthal in so many builds and be able to use TC. I saw one ad by Sigelli stating one of their mods will do TC with Kanthal, but of course Segelli makes a lot of claims that are simply false. I think Hohm has the corner on this market.
