SO i got my rx200, yesterday, bought myself 6 new batteries. Immediately upgraded to 3.0.. now this is my first go at ANY temp control device. So I have only experimented with my Tfv4 using the tf-Ti coils. I began using it from a room temp state on Ti mode. I have it set to 480, locked resistance @.31, wattage set to 56.0 w. I get a decent vape but almost immediately hits temp control. I came across this thread mainly because i was trying to figure out this mod and how the M1-m3 settings work, so I gave those two settings a show, I tried setting m1 to 366, and m2 to 352, both settings gave about the same vape as the Ti mode, and both also hit the temp protection almost immediately. AM i doing something wrong? or is it the fact these Ti coils are dual coils that is throwing it off? or is it working as designed? I also have a Kanger head ssocc coil that is Ni (red grommet), I don't currently own any temp wire, just a1 kanthal at them moment.
