Welcome to ECF, I'm wondering if something is possibly up with your build/tank? If only because the mod works otherwise with standard coils and your other tank? What tool(s) were you using to calculate resistance on your coil and whatnot? Or maybe something is up with wicking? IDK. There are some coilbuilding wizards on here, if you are able to post a pic of what you built, it might be useful? Sorry I can't be of more help, I hope that doesn't happen with my first build, though it quite entirely MIGHT.
There are other factors certainly, it might not be the coil, but it's possible you wrapped it on a resistance the mod can't handle? That's my main thought, but I could be way off base. If you just screw in the empty tank without a coil, what happens? Any weird error messages, then? Your tank might not be connecting properly with the mod, I guess is another possibility?
