Here's an update... seems like its got nothing to do with the coils.. problem lies with my 510 connection. The solder on the positive pin must have been damaged or something. I re-soldered the joint and all is well now. Not once did it jump out of tc. Thanks to you guys for pointing out that a loose connection between the coils and the atty got me thinking and finally found the problem!

Hi guys, I just got kicked out of tc again... Vaping on the dual claptons in power mode now. Just some food for thought regarding wire mass. Could it be that I've got way more Ni80 as compared to SUS304 that the chip keeps reading the Ni80 rather then the 304? Seeing as how the TCR of 304 is quite low. Will try to clapton thicker guage SS core (currently 0.4mm, will try 0.5mm but its in 316) and see how it goes. I've got another mod, the guardian III which keeps the mode in temp control and doesn't get kicked out. Another mod which I've tried previously was the evic mini with a TFV4 mini also built with the same coil but single. It kept on jumping out of TC too. Anyway, it works well in power mode but one negative point is the battery drain in power mode is higher and doesn't last me all day.. Thinking about it maybe I should just clamp down on the sus304 core from the post and try avoid the Ni80....hmm.

I think that your coils are heating up too slow. I think the initial raise in temperature should be more than 150 degree F in the first second. If this is not seen bij the DNA it will change over to powermode. You could try to increase the preheat/punch to see if this improves the situation. If not, post your profile settings and people might have other suggestions.[/QUOTE] Hi Bobby, Thing is that it was almost instantly when i hit the fire button, it came up with "OFF" on the screen. Cleaned up the coil by dry firing, new wick and its working again. Same settings. Will take note and bump up the preheat. My original preheat was 80W @ 6 hardness for 3 secs. My dual coils come up to 0.27ohms and i'm firing at 50w normal.

Hi Vapingbad, Ahh ok ok. which means my coil is kicking the temp control out? I've set the temp to 210 Deg C or about 430F or so.

Does anybody know what the Screen message "OFF" means? I'm running a hybrid coil of single 0.4mm SUS304 core claptoned with Ni80 38awg on an aromamizer dual coil. Mod settings on a VT200 are Temperature dominant with sus304 tcr profile When I fire my coils the main digits (usually showing current temp with the new firmware) shows "OFF"
