Crown tank burning

[Toallhisdoom]

So have had this tank for a while. Have loved it. Always run the .25 dual coils. Went through 3 or 4 coils vaping at 90w. Always great taste and vape production. Had no issue chain vaping.
I had the ipv3 li no issues. Now have the wismec rx200. Was fine. Updated firmware. Maybe this caused the issue seems to be around the time it started.
This past Wednesday I started getting burnt hits. Turned down to 75w. Still getting random burnt hits even with a day old coil.

Also when I let of the hit button and finish my pull I can still heae the coil noise as if it's still getting power for a second after I let off.

Using max vg juice. Never been an issue.

Any ideas?

As far as I know, the RX200 has TC for SS wire. All replacement coil heads for the crown are made of 316L SS wire. Therefore, I would use the crown in TC for SS mode on the RX200. It's working fine for me with my VTC Mini, and Reuleaux DNA.

Oh, one more thing, every mod is different. If you run your crown at 90W on your IPV3 li, it doesn't mean you can run it at 90W on your RX200.
For example, I'm running the same tank in TC at 420 degrees and 45W. However, on the DNA200, I'm running at 540 degrees and 47.5W.
