** so did ya'll talk about this and I MISSED IT ??
just ran across it and can't/don't remember any mention of it...

I'm not into 'sqwankin', just dig new gear...

Yea, that was talked about many many pages back. This page of the thread.

Okay, I am noticing some major Ω dropping on the Pico even with the voltages locked. The first 2 pictures were taken right after another, and I didn't even realize that the ohms changed until I uploaded them to the computer. I was actually going to show the ohm change between the TI and M1 modes, but it seems they change even in the same TI mode. Anyone else having this issue or know of a fix for it?
(PS. I have no idea how to make the images smaller when creating the post.)

And the ohm change between Ti and M1 modes.

I know nothing about these things, but wondering if a low battery might have something to do with it.

I've noticed it with charged batteries. I just put a fresh vtc4 in and the ohms still change between Ti and M1 modes. Haven't noticed it drop in Ti mode with the fresh battery yet today.

So are all 3 of those pictures in Ti mode? I could see that maybe there would be an individual resistance value for each mode, as that would make sense. I do want to say, that there seemed to be some slight weirdness to the resistance value when I first started using TC. I was never quite sure if I just remembered what the value was wrong or it shifted a couple of hundredths. I'm not using TC mode atm, so I can't tell you what it's doing now.

PS I see now, the top two pics are Ti and the third is M1

The first 2 were in Ti mode, (I took several but noticed later that the ohms changed in a couple of them) and the last one was in M1 mode. I had just switched it from ti to m1.

 

[Ed_C]

If you're in a different mode you would most likely be using a different coil, so it would make sense that it might save a separate value for each mode. Now if it really does that, I'm not sure.

 

[Ed_C]

I guess you could try re-locking the coil in both modes and see if they read the same and then stay at those values over time,

I'll give that a try.

Just tried it. At first it didn't work. In m1 mode I unlocked and relocked it and it said .76 Ω. Then I went to Ti and back to m1 and it was back at .56Ω. Tried it a second time and now in m1 mode it is locked at .81Ω. So I guess I'll see if it stays.

That's quite a bit of fluctuation. I'm not really sure about the TC on these things. My wife has a VTC Mini, which I believe to be the same board, and the both can be a little flaky. Sometimes it seems like when it hits temp protection the vapor drops way off. And then if you reset the resistance, it may not even change that value, but then it usually starts working somewhat better. I'm not really sure why that might be. I have been using a new Atlantis EVO, where the coils are non-TC, and I'm really liking that better than the Melo III with Ti coils. I may try a DNA at some point, but as of now, I'm not sold on TC.​

 

[Wackyjak]

I find in tc as the coil gets old or gunked the resistance gets higher. If you have it locked and you unlock it (wait for it to cool to room temp) and lock it again the reading will go up and you will get a good vape again. That or just turn the temp up a little as the coil gets old.. terntenmarschel.. maybe a little glitch but remember to let the coil cool to room temp before you lock it again.

I did, sometimes I cheat when I have to re-lock it. I will take cold draws on it without firing to cool the coil and then lock it when it gets close to the ohm range it was at.

Agree, Last time I tried to go back to a kanthal coil the mod went haywire. It kept shorting out at random saying no atty and then it would show the ohms and fire, and then it went back to 0Ω. Hopefully the next kanthal coil I try will work better. I never did find out why it messed up. I have noticed lately that I have to screw the tank all the way tight to get it to read properly. Before I could have it half way screwed down, and it would start reading the coil.

Not sure if the center pin on the mod needs to be pulled up.

When I got mi Pico I read where there was a ohm drop with the firmware it was released with. Was said to have been fixed with the first new firmware. I've updated mine once and left it at that. Ohms have stayed good but I've since put it in my stash and have been using my lavabox m 75.

 

[Ed_C]

I think I remember reading something about that as well and when I was seeing the drop, I was still on the original firmware. Those Lavabox M's look nice. How do you like it?

 

[Wackyjak]

@ Ed-C
I like it its built really well, billet aluminum. The battery door has a great feel to it. (now you can order extra batt doors in different colors also) I've only used it in tc with Ti grade1. I'm using the Ti profile it came with but it looks a little different than the one you can import from steam engine into escribe. I'm gonna have to make another profile with that trc and see how it works. With the way it is now I have to bump the temp up a little through out the day 440-460 or so. After it sits at night I have to lower the temp again. I like it.

That's odd, I notice the same thing with slowly increasing the temp to maintain a consistent vape. Why is that?

1. Put a freshly charged battery in the Pico as that one is almost dead.
2. Unlock the resistance in all modes. Switch to a locked mode, hold Fire and + to unlock it.
3. Take the atomizer off the the Pico for 10 minutes or more.
4. Go though each of the modes and hit fire on the Pico so it says Check Atomizer on each one and sets the resistance to 0.0
4. Now set the Pico to Ti mode and screw on the atomizer.
5. JUST TAP the fire button, DO NOT hold it or Vape off of it. That should be the cold resistance of the build in the atomizer.

It you want to test it in other modes then switch quickly and check them.

Resistance does not have to be locked for TC use.

If the resistance changes by a large amount or it kicks you out to VW mode and 20W then you have a problem with your build, loose screws, cut wires, loose 510 etc...

Really too bad you don't have another RTA to use as it would make troubleshooting your issues much easier.

I find that Ti mode does not work on the Pico, it vapes fine at first then as it sits the vape quality gets quite poor as the base resistance changes.

If your first experience of TC is on a Joyetech product, I can see where you would be unimpressed by TC in general.

I'm not sure if you can single out Joyetech products. Sigelei, Smok and others have had complaints about their TC as well. Accurate TC may be more than one can ask of a mod that sell for 25-40 bucks. When I can afford it, I will pick up a DNA. I've been very tempted by the Hcigar VT75s that are being blown out at $50. I know they aren't prefect, but they do have a DNA board.
