eVic-VT mini?

[gerrymi]

Had the mini for almost a month with no issue but then i only use it on VW mode.

But now the resistance reading is off by ~0.1ohm in VW mode.
I always have my build around 0.75ohm and its now jumping between 0.65-0.68ohm

Well...lobster...it's hard (for me) to understand where the "problem" is. What's GREAT about using VW is that it figures out what Voltage is needed (for the Ω's your topper has) to reach the Watts you want.

So...say for your topper and ejuice you've found that 40 Watts gives you flavor/clouds you like.

Set it for 40 Watts => VTC reads resistance as 0.8Ω => computes it needs 5.66 Volts => get 40 Watts.

Set it for 40 Watts => VTC reads resistance as 0.7Ω => computes it needs 5.29 Volts => get 40 Watts.

Set it for 40 Watts => VTC reads resistance as 0.6Ω => computes it needs 4.90 Volts => get 40 Watts.

So...you end up with 40 Watts no matter what the VTC is reading the resistance as.

Thus...you build for 0.75Ω...it reads 0.65Ω-0.68Ω...who cares...you'll always get the 40 Watts you desire.

I think u fail to understand how this and all regulated mod work.

When you set up a desired wattage, it reads the resistance, calculate the required voltage automatically, and then it fires the required voltage. Wattage is just a calculation displayed for you for your convenient. No, regulated mod does not magically measure wattage. There’s no such thing.

So what happen when the resistance reading is off?

Say the actual ohm on atty is :
0.8Ω => it needs 5.66 Volts => get 40 Watts

But since the resistance reading is off by say 0.1Ω

"VTC reads resistance as 0.7Ω => computes it needs 5.29 Volts => get 40 Watts."

What actually happens is it applies only 5.29v to supposedly 0.8Ω and in the end it only produce 34.98 Watts; even the device say its 40 watts.
Why? Because the wattage number displayed is just a calculation based on the wrong Ω reading and Volts; not a true measurement.


So yeah. thats the "problem".


The resistance reading on my vtc mini was quite precise when i first got it. Somewhere in line with my USA ohm meter and my other dna40's mods.

Not sure if its the chip or inner connector but certainly it now reads a wrong resistanc from less than a month of usage and this is not even my daily driver.


Not the end of the world per say but certainly a problem with my device.
Still gonna use it. Still love it.

Could there possibly be some schmutz forming on the VTC's pin? Just remembering all those times I had to clean the pins on my Spinners with an alcohol-damp Q-Tip.

Man, this mod's getting wonkier and wonkier. Too bad. I really wanted one. A white one with a black battery cover, topped with a black Squape Rs and a Yin Yang drip tip. See? I had it all planned out.

That would have been one fine looking rig Cindy!
You might have one yet depending on how this all pans out.

How is the Squape Rs? Don't tell me it is excellent...

I have the Squape R, and I like it a lot. Not my favorite, but once you get it up and running (some of the clones are wonky), it's a mac truck that's tough, always works, and super easy to build on and maintain. Problem is, it's way too tall - but the Rs is a full 10mm shorter with not much less capacity, which should be just right. Plus there's the new "B" deck that I've been dying to try out, in both anodized and ceramic. Something different - getting a little tired of the KF/Orchid-type decks that keep coming out.

Thanks Cindy!

I never thought about the R but the Rs looked intriguing.
Yeah, all there is out there is Kayfun/Orchid decks... We need more Taifun style decks like in the KS RTA and that "B" deck.

Thanks I have tried in Ni mode and it is the same problem. I do have lots of SS wire though, what resistance do you recommend?

no resitance in particular
i think,but weird thing today i made a .47coil cant get it to stick at temp ti mode
reduced loops,had a .40 now it works like a charm again

i guess go below .40 ohms

Maybe it was going over 1 ohm and kicking to VW mode?

Depending on wire type (316,304,430..etc) and set temperature that is very likely.

Wow, after weeks of using the VTC mini, I finally saw the new atty screen for the first time.... odd. Haven't done anything different than before. Still experiencing the same TC problem sporadically, maybe 20-30% of the time. Doesn't seem to be battery level after all, as it happened once with over half charge remaining.

Really hope they are able, and actually do get this issue fixed via firmware update. But even if they don't I'll still use this mod. Got some new drip tips, here is my favorite. Looks perfect on this RTA... almost like it was made to match it.

Just an update on my mini and for now it is in working condition..

My mini got a crappy 510 (see pic)..if I screw the atty all the way down..the resistance will started to go cranky again..

So far i have tested more than 10 attys and 4pc of TF GT 2 clone is working like a champ..

lobster...I think your reasoning may be a little philosophically impure...I'll have to think about it a little longer...

On the other hand...I think you'd agree...a $29 VTC can be forgiven if its Ω's readings are not quite as accurate as a $160 VF DNA40...

I dont wanna dwell into price vs quality mind games etc as it will be a never ending discussion and i grew tired reading about it. Out of context of this thread.


For me i bought the vtc mini purely because of its form factor and the spec fits my requirement.
Have an issue with inaccurate resistance reading. Not great but still usable, still bearable.


I think i speak for everyone who chime in their problems here are just looking for a solution.
One way or another i hope someone in Joyetech read this thread and come up with a solution (specially TC issue) And in long run improve their quality.


A great lcd tv used to cost $3000 up back then. Look how affordable they are now.


Cheers

Can't speak about experiencing the issues myself as I don't have any Ti wire yet but just wondering how did you exactly notify Joyetech about the problem you got?

 

[Rockwell222]

Email them which seems pointless since I sent one with a in depth explanation of what is happening about a week ago with no response. All my wife can use it in is VW mode and that's it, TC is extremely irritating and works 10% of the time.

I emailed too, heard nothing back.

 

[Tpat591]

I would think if I emailed Joyetech with my issue & they did not respond I would Email them again, attaching the original email and express my disappointment in their apparent ducking of their after sales service responsibilities. I would threaten to post my experience on e-cigarette forums across the world Warning the Vaping Community to think twice about buying a Joyetech product because they do not respond to after sales service request in an effort to have the warranty time out before they are forced to service the warranty.

Willing to bet they will respond differently. I would also start a thread for people with same issue to post their reports of the same behavior employed by Joyetech to be used to provide links to in my third request should they fail to respond. As that thread grows, the consumers power over a company to take corrective action grows exponentially as the posts can be consolidated into a single running document showing a repeated behavior of failing to properly address after sales service requests adequately on their part that can be used if necessary by others seeking to resolve their issues.

I have put forth this concept many times in an effort to help those experiencing issues but this has apparently fallen on deaf ears with no action taken. As far as I am concerned, at the very least you deserve to live with your issues because you have not taken steps to put this in place, or you are being paid by Joyetech's competitors to Troll the Evic VTC threads to discredit the product enough that a consumer might just choose another product instead.

Wow... You might just watch a little too much TV... Really?

 

[Rockwell222]

Hahahaha wow. All I know is it's not worth half the stress I've put into this. I've tried the vendor and they let me me down to say the least and tried joytech and they did the same. I'll wait for an update if one ever comes and I'll buy a ipv d2 for my wife so I don't have to put up with these TC issues as of now.

 

[zeus01]

@Rockwell

bro i suggest for now,
use ss wires
on ti mode,tc still works not just accurate and start at 200f


as for thw other guy

well since you are so brilliant why dont you start a thread and do us all a favor

after all we are paid right
