DNA75 Preheat doesnt work...

[inteks]

thats an other prob i have with my dna. if i dont lock ohm and im vaping outside (its cold) the chip goes far too low with detected ohm value and i have to raise the temp up to 300°C (max) and it still not hot enough.
normally i let it cool down at room temp check resistens and lock it.

Yeah, I do that occasionally (Canada, eh.) 

So are you satisfied with your TC settings now? 
How many different 'profiles' do you use, or will use?
