hi Grad.
I think that you're at the lowest possible power settings for the MVP2 (3.3 V, 6 watts). I think the only way to decrease the warmth is to use a higher resistance atty with the 3.3V setting. You could also try taking shorter drags so it doesn't heat up as much?
Agreed. Assuming the atomizer / coil head is OK, you'd need a higher resistance one to correct the situation. Have you actually done a resistance reading on the head? Or are you just going by the box it came in?
I've had heads go bad and change resistance on me causing basically the same issue. Like if 2 of the coil wraps started touching, would reduce the resistance and create a hot spot making everything pretty nasty.
Another issue to consider is if the coil ever got overheated. Some wicking material, once it gets burnt, will never lose the nasty flavor even if you crank the volts down. I've done it myself before where when I changed the head my voltage was initially set too high. After hitting it a few times I realized I hadn't adjusted and even after setting it properly it still tasted bad.
The above can also happen especially right after the first fill. It takes time for the wick to become thoroughly soaked. So right after installing a new head and filling, you really want to start out on lower voltage settings and take it easy on the vape frequency until it starts vaping well. Then you can slowly work your way up to the proper voltage that suits you.
It could also be the head itself just having wicking issues. That would also lend itself toward burning the wicking material.
My next step would be to try another head, but following the above about starting low & easy.
If the tank you mentioned is actually a carto tank, all of the above still applies. Just wherever it says atomizer, coil, or head insert the word carto.
