Yep, the quirks of the 20W iStick take some getting use to The Nautilus coils are only 1.6 or 1.8 Ohm as Tam pointed out, so you can't go higher there. The only option is to go lower Voltage or Wattage. I've found that the iSticks are less prone to running "hot" if they are in Voltage-mode, but even then, if I were running 3.9V (10W) on a different device, I have to translate that to 3.2-3.4V (6.8-7.7W) on the iStick to get a decent (not burnt/hot) vape. As the battery wears down a bit, they tend to smooth out a little. So it does take a little playing with them. They're not as accurate or smooth as say, an MVP, but they do work

I'm using one right now with a KPT2 tank and 1.5 Ohm coil. I have to run it at 3V (6W) or I start getting a slight burnt taste. As the battery wears down, I can take it up to 3.3 (7.3W) and it will work well until it needs recharging. On my MVP, I would be running that same tank/coil combo @ 8.5-10W from the start, and never have a burnt taste.

It is just a thought, but do you think the burnt flavor could be stuck in your coil or the juice in your tank? The iStick 20W does not buck (lower voltage below battery voltage) very good (if at all). So when it is fully charged it would be putting out close to 10 watts. My personal experiance is that fruit flavors like you are using are generally best for me in the 10+ watt range.

* the wattage numbers I am using is based on the assumption that you are using a 20watt iStick and not a 30watt iStick. The 20 watt uses a nonstandard measurement system that makes it much hotter based on the numbers on the screen. 9 watts on an iStick 20 is equal to 12.8 watts on most other devices.

How strange. Just went looking for 2.2 ohm coils for the Nautilus BVC but only found the 1.8 ohm as the highest resistance. Sorry!

Your next step then, is to see what the PG/VG ratio of your juice is. Like Jason said, a 50/50 blend is a good one to make sure you get the vapor as well as the right viscosity so that your wicks can soak up the juice.

What ohm coil are you using right now? Is it the 1.6 or 1.8 ohm? It should say on the base of the coil itself.

I always change my settings until i find the sweet spot for the juice. With that said, is it a dry hit or burnt hit? I am not familiar with your tank but many people will be.

The Eleaf iStick tends to run a little hotter than what the display settings indicate. You can counteract this by getting a higher resistant coil for your Nautilus mini. The coils that come with the Nautilus mini are 1.6 ohm and 1.8 ohm (if I remember correctly). You'll want to go with a 2.2 ohm or higher so you get a cooler vape without the burning taste.
