TWWhat works for me is just setting it to kanthal TC mode with the latest firmware 2.5.7. I'm not needing to mess with the FSK, but if it doesn't seem to work for you go ahead and change the FSK to your liking.
Thanks for the reply. I updated the software as soon as it came in yesterday. I had to move the FSK down. I was getting a strong cotton taste with the fsk value set to 50. I had to move it down to like 32. Not sure I am doing it correctly, but this is how I set it. I put the tank on at room temp. The wicks are wet. I move the fsk value way down, hit the power button keep moving the fsk value up until I can detect the coil starts firing. I start getting a little vapor. I usually set my temp to 420. I know I am not doing somethng exactly right though, because I can still get a strong cotton taste if the coil starts to get a little dry.
