Temp control setup SS316 coils

Hi all! Got some questions about temp control vaping that I'm sure have been answered here somewhere before, but I can't find the posts .

I've always been a mouth-to-lung guy as this is really just a smoking diversion for me. But over time I've went from an aspire nautilus with coils at 1.8 ohms, to the Joyetech cubis pro with ss316 .6 ohm (mtl) coils, just kept needing a bit more punch to stay away from the cigs. But what I'm realizing is that with these lower resistance coils, while I'm getting a much more satisfying vape, I'm also getting increasingly more common dry hits. Therefore I began exploring temp control vaping, and the results are pretty much what everyone says about TC: consistent vaping experience, I literally do not get dry hits and it's great, but now I want to fine-tune the experience, which brings me to my questions...

I originally watched a video online, can't find it now and can't reference it unfortunately... but the guy was using the same equipment as I am now (hence the reason I used it for learning). I'm using a Joyetech Egrip2 with a Cubis Pro tank. The coils are SS316 and .6 ohms as stated before. The recommended wattage range on the coil is 15-28 watts, and this is where I get confused. The guy in the video originally set his wattage to around 50, at a temp of 500 Fahrenheit, and seemed to vape fine this way. But the first thing I thought was, "this is way outside of the recommended wattage range stated on the coil". I keep mine around 25 watts right now at around 470 degrees for most juices (50-50 pg/vg blends). There is some ramp-up time, and that's what I'm trying to get rid of (or at least thoroughly shorten).

I found that pushing the wattage to around 35-40w gives me a very smooth, warm vapor that I like instantly, but with some burning in the flavor, however, no ramp up. It's almost immediately at the warm temp I like it to be right away. My gut is telling me I shouldn't be pushing the coil beyond its wattage range, but everything I've read about TC so far makes the claim that wattage only becomes a speed-factor for ramp-up time, and the temperature itself is now the controlling factor to whether or not you are burning your coil. I can keep the temperature exactly the same at 25w, but it takes some time to reach my desired temp, and also the hit immediately dies when it reaches that temperature, flavor and vapor production seem to stop when it reaches 470 with the temp protection, however, no burnt flavor. Protection may be there when I push the wattage up to 35w, but at least the hit doesn't suddenly die halfway through my pull.

So, with all that said (and sorry for the lengthy post, just trying to get a thorough understanding), here are my questions:

1) Do you still need to stay within the recommended wattage range of your coil when vaping in TC?
2) Why would the flavor be burned at a higher wattage if the temperature is exactly the same?

Any help is appreciated, thanks!

1) There is a limit to the wattage a coil can handle before the wick burns. TC or not. If you exceed that wattage, TC wont help. Set your coil to where you like it, then switch to TC, then you can make a bit of fine tuning adjustments. (Mine goes up to +10%)
2) Flavor is burning because you are heating your wick faster than it can pull juice, what you call "ramp up". You need to give your coil time to heat the juice in the wick so it gets thinner and draws ejuice better, so some ramp up is needed. It doesn't have to be a long ramp up, but an instant hit is not really possible unless you want to burn your wick. Try blowing air out through your coil before you inhale to allow for the ramp up. Not alot, just a small outward puff to let the ejuice heat up some. Then set your TC. It should fire at the same temp every time, with that small outward puff to start things up.

The thing about TC and wattage is that the mod is going to pull it down to what it wants. This is a DNA200, red is temp, green is power and yellow is amps. My preheat is at 75 watts and the power set at 50 watts. SS316L 0.23Ω 24g
