UFS2 help please?

[rojo]

Hey,

I'm not having much luck with my UFS2. I can't figure out why it's flooding my atty every time I try to use it.

I put Vaseline on the threads and O-rings on all the parts I've disassembled. (I didn't take the center pin out of the bottom connector assembly though. Should I?) I put it all together with a CoV dual coil atty. I screw the air hole ring all the way down and unscrew the bottom of the juice well until it's tight against the bottom of the atty in its fully closed position. I put in a mil or two of juice, screw the top of the juice well down, screw the top collar down to put tension on the O-ring surrounding the top of the atty, and pop in a drip tip. I unscrew the air flow collar about 1/3 to a half turn, and try to vape. Immediately my atty is flooded, in spite of the juice flow being in its fully unscrewed / closed position. Gurgle gurgle gurgle, splash into the mouth, and sputter spit gag brush teeth. Whether air draw is stiff or fully open seems to make no difference. I'm not having a good time.

I've been studying Zoranth's schematics, watching YouTube videos, and all I can deduce is that either my UFS or its user is faulty in some way.

Does anyone have any tips?

Try closing the juice control ring before you close air when filling it up. Also having the air flow only sliightly open like you do feeds juice easier than having it completely open. So you may want to open that more. Don't screw down the top cap too much either -- I've heard that from multiple people.

I see that you follow the right peossedure rojo. The 2 things that are happening are:

1. Bad quality atomizer with no flat base
2. a gap between atomizer and base of UFS when liquid is in closed position

The solution to this is to try 2 more atomizers. If they are from different ventors would be better. If you see that same thing is happening then you have to take a look to the hole on the base of UFS (where it meets the atomizer in closed position) to see if its ok.

Also keep the upper small cap tight

You know, my atty doesn't have a completely flat base. It's got a horizontal notch cut across the center post. I guess the CoV dual coil atties aren't very well suited for the UFS after all. I'll try a Joye atty and let you know. Thanks!

The draw's a lot stiffer now with a Joye atty. I'm not getting any vapor at all now, but I think I might have juice filling up the UFS's nether regions. I'll have to take it apart and rinse it out when I get home tonight.

For now, the Joye atty is showing some promise as the solution to all my problems.

Many people say that Joy atty works exellent inside UFS rojo. But you overflood it so no air comes to your mouth. Blow air via 4 holes of the VT so liquid inside it will come out. Do this with liquid closed

DC atty from COV works great for me. However, I use Joye LR510 mostly.

When I fill my tank:
1. I close the liquid off completely and then the air. Remember, CCW closes liquid, CW closes air. Even then, I get a lot of liquid into the collection tank and hence into the atty when I start vaping. So... I leave juice control closed, open air control and vape till it isn't flooding anymore.
2. Then it's 1/4 turn on air and ~ 1/4 on liquid from the closed position on both. Perfect vape for me with PG/VG (80/20), LR510, @3.7v. I close both air and liquid if I am putting it in my pocket, otherwise I leave it set.

3. Also, I noticed if I fill it ALL the way, it tends to be harder to get it to prime on it's own. So I open liquid a little, leave air closed and prime it ever so slightly (just hear a little gurgle of liquid), then proceed w/ #2.

This has worked for me on both UFS's I have.

You don't mention what type of liquid you are using... I had a lot of issue with 100% vg, but that's because I am so used to using 70/30 or 80/20.

Good trick to keep in mind for the future. My UFS is already in pieces sitting on a paper towel waiting to dry, though. But I did make sure to blow through the atty connection.

I'm using 50/50.

+1. Just tried the 1/4 turn & it works perfectly. I'm using 1.5 DC atty w/ 40pg/60vg

Imeo, you were right. Using a Joye atty was the solution. This UFS2 is finally working for me. Thanks Imeo!

I've still got to figure out how to dial in the taste and vapor I like. I'm pretty close, I think, but I'm not sure how high I should set my expectations. At the moment, I estimate that it's about half as intense as direct dripping. (I'm doing a side-by-side comparison: UFS2 on a AW IMR-based 3.7v battery mod with a Joye LR atty, versus an eGo battery with an identical Joye LR atty.) I'm vaping 50/50 PG/VG, and have the juice open about 1/3 a turn and air flow open about 1/2 a turn. If I open the juice flow more, I start to get a little gurgling and I think I need to back off.

How rich should I expect the flavor and vapor production to be? Can you UFS veterans compare your experience to direct dripping?

Wow, JR, have you been watching me?!?!?!? Great advice, its what I would've typed!!!

Awesome...I love how we help each other!

I am glad that I helped and that you are close to success rojo

I let Vaporologist borrow my UFS for a little bit. He said he had the same results as I -- disappointing flavor and vapor in spite of studying all the howto videos and following everyone's advice. He traded out my Joye 510 atty for one of his own and he says it hits like a freight train now (throwing in a couple of wow!'s for extra effect). He says he doesn't remember when or from whom he bought his Joye atty, but I guess it's different enough to have a significant performance gain in spite of being spec'd basically the same as mine.

Matter of fact, the one I let him borrow metered at 1.4 ohms! So, if anything, mine was a little more impressive in theory; just not in practice. It's a little disappointing, since my atty will pretty much knock someone's head off with direct drip. I guess some runs of mass-produced atties just feed a little differently from others of the same brand and type. That's one of the problems the hh.357 claims to solve.

I'mma let him play with it for another couple of weeks, then I'll try it again with some IKV XLR510's. If those don't work well either, I might order an hh.357 or two.

This UFS is going to impress me sooner or later, by God. That's just all there is to it.

That's the spirit Rojo! Keep with it buddy! It will all fall into place for you and when it does, you will see that all the efforts to learn the use of it are well worth the time it takes to master the UFS!

I am looking forward to the Odysseus but am in no rush as I am a very happer camper with the vape I enjoy with my GGTS and UFS!
