I'm not sure if this has been covered very well. I'm aware of several complaints of pre-heat rush with the 40. I've experienced this problem recently and it isn't a problem with my chip. I do agree that this is an aweful experience. Beforehand I couldn't figure out what all of these people were talking about. The chip has worked exremely well for me since it was first available to the public. This is what I've rationalized as problems so far:
Loose contact(s).
Improperly sized connection hardware and/or wiring.
Inadequate quality of connection metals.
In my case there is a new atomizer with a split center pin design. I reversed the direction of a pin insulator and this allowed the center pin halves to make a solid contact.
I only run spaced coils and this is the only other caveat that I've found. coils that are spaced but a bit too close together have caused intermittent problems too. Great if contact coil configurations are working well for you, they have proven inconsistent at best for me.
The poor vape quality due to pre-heat rush is bunk as an attribute to the dna40. The connections must be tight and of high quality for the chip to properly track the coil resistance.
