I am very new into tanking and am having one problem after another. Please don't comment by having me throw it in the garbage. Ill run through quick as to not take to much time. 1. First use of vivi nova out of box perfect. 2. First problem wick getting thick and gummed up at top making me refill with almost a full tank to get it going. I beleive the attys come with voltage around 3.4 ohm or so with a new purchase of tank, but the replacements I found are around 2.5 , should that make a significant difference? Now new atty pops and crackles spitting up hot juice from the drip even at 4.0 voltage. I have mod 3 to 6 v. It gurgles and doesn't vape well. Now it tastes burnt. I'm wondering if I should be looking for a specific brand of attys or specific ohms for my vivi nova. Or is it possible another problem? I'm very frustrated and just want a simple good vape. I don't know anything about other tanks, but I have invested a lot so far with what I have, and would prefer not to have to by new stuff. The vivi nova is very simple to take apart and replace the atty so what is the problem? Ok not so brief, thanks I'm pleading for help.
Vivi Nova need help please

I'd check the mod's output with a volt meter if you have one. What their set at and the true output may be different. I have one that says 4v but the true output is 4.5v. Atty's ohm can be off as well but usually fairly close. Some liquids gum up an atty faster than others. If that happens I use a lower ohm atty for that liquid. Vivi Nova is my favorite & I use a 1.8 atty for everything on an ego t-mod. At 4.2 v it burns on the warm side depending on the liquid. On regulated voltage @ 3.7v & 1.8 atty its perfect for some liquids & not as good for others. I've never tried a 3.4 ohm because it take to much voltage. A 2.5 ohm should be fine but once again what your mod is set at & what the real output is may be different. In general I stay on the lower end of atty ohms and on a VV unit adjust the output as needed.
I do have a volt meter, I know this is probably in other posts, but since we are here do you know a general range of atty ohms verse voltage? The 3.4 came in the kit, but the ones I have now are lower. I'm going to have to look at them because when I ordered them I didn't know what the ohms were related to. I just ordered some that are 2.4 so ill see what difference it will make. I know my problem started when I used up the ones from the kit and replaced them, I just didn't know why. I like a strong vape, but I don't want to keep burning these attys up. I have an ego twist too and it seems more stable actually volt wise but it does not have a display so I just play with it to find it where it works. Is there a big difference between attys and where they are purchased? I have gotten them from Vaping zone where I got the VVmod, and replacements from myfreedomsmokes and vapor king. I assume they would sell quality since they are reputable. Today I'm going to switch out they addys and try again. What about the mechanism in the tube that goes from the atty to the battery, the part the atty screws into? I did clean the whole assembly with water and let it dry. I wondered if i didnt let them dry long enough and need to by a new tank? I did not clean the atty I just replaced them. Thanks for the good words, I really need to get a base knowledge going.
Did you get a Vision Vivi or is it a knock off? I have a knock off and the first head I had was great for all of 3 days, now I have nothing but problems so I ordered an actual vision vivi nova because they are super easy to clean and rebuild the heads. Hoping to have better luck.
First, as previously mentioned, make sure you have a genuine Vision Vivi Nova and not an imitation. Quality on the actual Vision unit is a much more known factor. Second, if you've dropped the resistance on the head, you will need to lower the voltage as well. Tasting burnt is due to one of two problems: either the juice isn't getting to the coil easily, or your wattage is too high. Try lowering the voltage gradually. Each head should have the resistance stamped on the side of it - genuine Vision Nova heads come in 2.8, 2.4, and 2.0 ohm versions. 3.4 ohms suggests it's a knock-off. Try dropping the voltage as low as your VV device goes and working up gradually in .1 volt increments.
Last, do you know what the PG/VG ratio is in your juice? The Novas are best with juice that isn't too high in VG, because VG is a lot thicker and doesn't wick as well to a top coil. I use the Novas often and am very happy with them, but I don't vape juice with more VG than about 40%.
Based on my personal experience, Madvapes and Surevapes both carry genuine Visions. I believe Gotvapes does as well, but I don't order from them so I can't say for sure. Others can probably add vendors to this list.

Rick has a good point above....^^^^^ Real vivi's come with a 2.4 ohm coil installed and a 1.8 and 2.8 as spares. If you are trying to run a coil reading 3.4 ohms with low voltage it is going to gunk up and cause problems cause it is not burning clean as the coil isn't getting enough voltage to properly atomize the liquid. A coil with that amount of ohms should be run around 6v to get a clean burn. I would get a new coil for it or rebuild the one you have or just get a real vivi. Just my 
Good luck with it....
Good luck with it....I think I did not get the real deal. I don't know if that is the problem I have recently noticed where a new juice, atty and tank still have a funny off taste. I have eliminated everything but the fabric around the coil. I think this is what is giving an odd off taste. Is this a knock off problem as well? I would like to remove it without rebelling but have not figured out how to do that. I am using Kanger t3 mostly now because I just could not get what I wanted out of the vivi. Oh I got a smaller vivi and noticed it does not have the fabric around the coil and it tastes good and pure. I may just look for some genuine replacements and see if indeed that is the problem. I even did a dry burn and clean on the smaller vivi and it was perfect. It has to be that fabric.
I disagree: The Vivi nova for the price is very good, and an excellent base to mod. Here are two that give monster vapor and flavor.
5 wraps 30g 2 ohm on a BD13 ceramic wick with two 2mm hemp overwicks.
6 wraps Oval 28g coil, bamboo threads thru the coil, cotton overwick.
Vivi Nova is all I vape, but there was a learning curve.
1. Anytime you change ohms, you have to change your voltage. The higher the ohms, the higher the volts you can use.
2. I always always soak new heads in vodka overnight (in a pill bottle), shake the bottle before pouring out the vodka, pat dry with a paper towel, and air-dry for 2-3 days. I do this immediately when they arrive, so that I have them already washed when my old one needs to be replaced. Heads last me a week typically, but it can be as little as 2 days or as much as 10 days.
If I rebuild them myself AND remember to flame and wipe off the Kanthal before using, I can skip this step.
3. The longer I use a head, the gunkier it gets. I use a fairly-thick e-liquid. I like it so I'm not going to change it. This means that although on the first day I have pretty thin e-liquid and can vape the tank down below half before topping it off, by the end of the week I'm having to keep it above the 3/4 level (or higher!) at all times in order to get a good vape.
4. You must ALWAYS tilt-and-roll between puffs with any top-coil clearo including the Nova.
5. I get a better vape if I make sure the wick ends are not quite touching the bottom of the tank, so I shorten the wicks slightly, which means if they are silica wicks I need to wash off the cut ends and pat try before using.
6. When putting in a new head, make sure it is mostly finger-tightened with DRY fingers. Not super-finger-tightened, but not slippery-finger tightened either. And put 1 drop of juice in the center of the head before putting that little cap back on. Then add juice to the fill line, close, tilt-and-roll, and let sit for 15 mins before using.
I know this sounds like a lot, and if I'd had this list before I had failed at so many other devices, I would have never ordered them, but they are the best I've found so far, and a lot of this is "Best Practices" rather than crucial. The only really non-negotiable items on the list are #1, #4, and #6.

Yeah, if you get your hands on BD13! lol. I can't wait until someone releases this new wick.
Its true that 3,4 ohms are a lot for a low voltage battery.Wouldn't vape that good on a standard ego battery i think.Needs more powah!
Never seen a vivi head at 3.4 ohms, 2.8 is the highest I know of. I have several VISION vivis as well as a few SMOK vivis and its a night and day difference between the two. The smok vivis give me a burnt plastic taste NO MATTER WHAT. The visions I have ZERO issues with, even vaping 20/80 PG/VG which is pretty thick. I get up to 6 weeks off of a single coil with washing/cleaning it every few tanks. No dry burns unless its really crusty. @ $2/ea for a coil head, I just toss em when they kill over rather than fiddle with rebuilding them, not my cup of tea. Hope you get it figured out.
