Cheers slinxy, i did find a find a few videos last night, and the thing that i didnt know or didnt understand was the 'baseline' setting the dna uses on the first press - all the time i had been coiling the squape i had been using the dna, which in turn made that warm, so with a cold atty on it it was using the wrong baseline, so this morning they were both cold i whacked it on, selected new coil and it seems to be working perfectly well, no temp protected so far.
Edit - Only thing its doing, is everynow and then it jumps out of TC mode and goes into normal mode, but a simple press of the button again and its back to firing in TC - Not sure i like the vape though, its totally different
What I tend to do on my dna40 is to pre-heat the coil, then slap it on the dna40. Yeah it doesn't give me a true temperature reading but a match better vape. I really want a play with the new dna40 to see how the atty lock works on that, but my personal preference is the SX mini j; it just works.. Wonderfully, and I'll be getting a vaporflask SX mini j when it comes out.
