Ok, so problem has been identified. Sort of. The mod...at least mine, does not like the sub tanks, either style....I will try the RBA soon (though I hate to scrap the great ni coil I've got on it [emoji14]).
I've switched to my airek, first I built a dual fused macro coil build.....no go, dry hit kicks on immediately. So I pulled the build, and threw on a simple 1 ohm spaced coil with 26 gauge. I'm actually seeing proper behavior. First 4-5 hits, zero wattage change..the next few hits, wattage drops by end of hit, then, dry hit kicks on as intended.....
Call me amazed, it's working perfect right now!
On a side note, I had a dual stovetop on the airek, so I tried it out before rebuilding....no go on that. Dry hit protection (I'm going to call it DHP from now on for ease) never kicked on, wick was charred quite badly [emoji14]
