Help with the Tubo Evic not producing vapor

I recently received my Tubo Evic I ordered back in April, and have been testing it out for the last few days. I don't know if it's me (which is entirely possible,) or the unit, but I can't seem to get any vapor out of it until I hit about 410-420c.

I'm sort of new to vaping still, and I've owned a Mighty for several months, and that thing puts out really nice vapor at 370c, which is where I like to stay at. I realize that's a hybrid, and the Tubo is full convection, but any video out there shows the Tubo putting out clouds like the Mighty at similar temperatures.

I've tried everything. Coarse, medium, and fine grinds, tight and loose packs, different amounts in the cap and stem, tried the coil settings, did a warm up hit and very slow draws to get heat into the flower, cruise and on demand, and nothing. The temperature readout is perfectly in range to what it's set at, but I don't see visible vapor until at least 410c. Even then, the vapor is very very light.

I get an OK amount of flavor and some buzz, but absolutely nothing compared to the Mighty. I know the Mighty is top tier and I might just be spoiled on it, but I really feel I'm missing something. Any ideas why I wouldn't be getting vapor?

I just got the Tubo X, and I am using very high temps to get a reasonable vapour.

It really depends how you load it - mainly how close to the heater the herb is.

With vapes like these, it's impossible to get an accurate temp in the bowl, because thermometers can't physically be placed there. So you have to fine tune how you load and draw the device by the colour of the ABV. Combustion happens at 240 degrees celcius, if the device is turned up beyond that and there's no smoke, then the herb is cooler than 240. It's all good if it's all vapour. I combusted with mine set at 260 C, but only when I changed stems to an adapter with a screen/chamber closer to the heat source..

Ideally you want to load the herb as close to the heat source as you can in order to get the most accurate control over the cooking. Mine is set at 240 C and I'd guess from the ABV I'm hitting 220 C in the chamber. That's just within my tolerance, probably a bit out

If it seems really off, you might need to adjust the coil resistance..

I've tried changing the coil resistance as per the manual, but from the temperature output on screen, it's set correctly out of the box. putting it up .001 made it run about 10 degrees more than what I had it set at, and lowering it was the opposite. I'm trying to run mine at lower temps, right about 370C-390C. The stem is as close to the heating element as it can get. It just seems like something is actually wrong, as I get a very light vapor at 410C, whereas on the Mighty I'd be coughing clouds out until tomorrow.

It might not be possible to set it as such.
The Mighty when it is set at 410 is controlled in such a way that the chamber itself obtains this temp, and conduction and convection from the air bake the herb.
With the Tubo, the chamber is not directly relative to the set temp, which controls convection based heating. In use it blasts hot air, and that hot air is transferring all the heat.
Cooler air is much less effective, so dialling it up helps make clouds. The temp readout is probably not very accurate, unlike the Mighty, so setting higher temps does not mean you're necessarily exceeding the Mighty's set temp, even if the numbers are quite different.

How long do you preheat ? Do you vape in on-demand or in cruise mod ?
Enter cruise for 1 min and then try hitting it. You can pm me if you like for more advice .
What type/brand battery are you using?

--------------------------
Damn i am vaked. Now i read again your posts. I think you have mistaken F for Celsius..
Dude it is normal to not have visible vapor below 200 C (410F ). Anyway if you like you can make 200C hotter by adjusting the resistance ,but you will have to go up a lot more than 0.01 to have noticeable effect. 25 C offset is not so little. try like +0.05 and then go in 0.01-0.02 steps until you get desired results.
Temps displayed are temps of the heater not temps of the herb chamber. In mighty there is conduction and temps are measure at the heating chamber which is also the herb chamber.

I'm having another issue with it now so I just contacted fj through the site with all the pertinent info. With preheat, I'd do the warm-up to cruise setting, and during the first minute of the cruise, I'd do some small cigar puffs mixed with some very long, very very light draws, to try to get heat in the chamber.

It is definitely normal to have visible vapor below 410 C. The Mighty was my first, and I get clouds at 370 C. I know this one's full convection and the Mighty is not, but check this out, this is a video of a session at 360 C on the Tubo (NOT ME btw, found on youtube)


That's what I want out of my Tubo. Average - good vapor at around 370.

How do you know that this tubo is just not set too hot. As said 400 F (200C) Is temperature of the heater which is calculated based on the resistance shift which occurs during temp changes.
Anyway keep increasing the resistance until you meet desired results.
I am sure there is nothing wrong with your tubo, you can set it up to do the same as the one in the video. You can make it combust at 150 C if you like..
This video is also done in daylight which makes vapor way more visible.

@sumobudhha I had this issue with my Firefly 2 (first vape) took a few hits to even see vapor and I ended up getting frustrated and moving on to other vapes, recently I pulled it back out for kicks and giggles and now I get vapor first pull using different methods learned while using others, I would say for starters do very slow pulls, the old sip it not rip it technique. Learning a new vaporizer can be a task but once you get it you will be enjoying yourself, if you still have your other vape or if you have a few try putting the evic and the shelf for a minute and then go back to it and give it another go. Hope this helps

There seems to be a coil issue or something of the like. Not sure exactly what happened, but before when things were sort of ok working, I'd set temp to 370C, coil at .237, and power was max 70w. While firing, the temperature stayed around 370C, coil ran at around .311, and power was around 30w while inhaling in session, 50-60w using on demand.

Now, with those same settings, while firing the temp reads anywhere from 500C to 850C, coil goes from .350 to .410, and power doesn't go above 2w. And it doesn't feel like it's actually getting hot.

I sent a message to fj through lamart.ch about my order and my problems, to see what's going on.

You're using 400c? I keep mine around 350F and have no problem with getting vapor pretty quickly. I do use cruise mode just because it's easier but I have it set for 60 seconds. Within that time I get lots of vapor. I have no idea what is wrong with your tubo unless you have it set too high. I don't think it's a new vape technique issue.

I also didn't ever change the settings except the heat and timing on cruise mode. It just seemed to be fine the way it was.

Holy crap everyone I'm an idiot, I've meant F this entire time, not C. Issue still stands however. I also have an issue now where when I fire the unit, it says NewCoil 0.33 ohms Right, SameCoil 0.23 ohms Left. Not sure if anyone has had that before. I've messaged fj through the lamart.ch with all the info, Thanks for all the help and info everyone, it's all greatly appreciated

Are you using the Tubo firmware from the lamart website, and staying in TCR mode? You want to make sure that the coil resistance starts set to whatever fj has written in your battery cover, then you can adjust from there. If you keep having issues with the firmware, try reflashing it from the lamart website, then re-entering the resistance setting for your device. If you need it I can write up a tutorial for this.

As for vapour, I don't see much vapour from the Tubo, even at higher temperatures (220/230 c). Even so, it's super effective for me. Vapour does not necessarily equal effectiveness or taste! I have found, though, that the key to vapour from this device is to let the herb heat up by drawing hot air through it, and to draw hard at a high temperature. It sounds like you're taking lighter draws, but the Tubo can support draws of any intensity. Try really sucking on this thing, you may be surprised by the clouds. Also, the stem you're using can affect the cloud production, I've found bigger clouds with the shorter stem. Packing might also be an issue, depending how dense you pack or how close you pack to the heating element. Try experimenting!

With comparison to the mighty, I definitely got bigger clouds on the mighty than the Tubo, but for me, the effect and flavour of the Tubo blow the mighty out of the water.

That video is of me with the stem packed basket screen right at the end with no cap and I have never changed the resistance from what is on the door.

Turned out to be a bad coil. I've already sent it in, and had it repaired, and received it back today! Been giving it a good test all day, and the difference is night and day. It's now exactly what I originally envisioned when I ordered it.

My first run in with a DOA anything, but hey, shit happens. Took some extra time, but things are running smoothly now. The coils even glow during heat-up and everything

I'd say the vapor quality is about the same as the mighty, maaaaybe a tad less. Hard to tell, that's how good it is. Definitely hits like a champ, and out of my now 3 vapes, this will probably be the daily driver, with the Mighty and the Arizer EQ as backups.

I believe that if the resistance is set properly, you would not see a glow during heat-up.

I also do see the coils glowing slightly in the dark. For me they have to behave like that, otherwise, if I'd lower the resistance there won't be much vapor.

Thing is that people get obsessed with getting vapor at a certain number shown on the screen coming from their vast knowledge of vaporization temps,but they forget this is the temp of the coils calculated based on resistance changes,and conduct heat to the room temp air which will hit you herbs sitting in heatsink (bowl) . There are probably almost zero convection vaporizers on the market which give you live feedback of what is happening with your herb tempwise,not to mentioned that it is not the same thing happening in different area of the bowl..Even with the most even extraction there are areas in the bowl which are to say more even than others ) .(joking with the risk of getting lost in translation )
If you wanna get thick vapor at 175C - 180 C Yes you coils will glow at 260. If your coils dont glow at 260C and you vape at higher temps like 200-220 C you will get the same results as at 175-185 C for example.., The only difference is that you wont satisfy your numeric desire but you will insure yourself that your coils. I personally dont even want to have the chance of having my coils glowing even for a second,which might happen if i tune the temp too high by accident and also will happen everytime in warmup mode.
I am the princess from the princess and the pea,i've said it before.
@sumobudhha Glad you got it figured out,dude ! It really sucks when the solution to a problem is out of your hands ,but it is all well if it ends well :").
