Hey, sorry I got busy yesterday but let me explain why I said what I said.
Firstly, I was going off two pieces of information. What Yihi themselves said, they said they were using Joules because to them, it was more important to keep track of consumption rather than wattage.
Now in this they have a point - so I will insert my limited knowledge of vaping here. I currently have an ego and am about to upgrade to an istick (coming soon) so, what everyone has told me is this, higher wattage = increased consumption. I will consume more as a result therefore I will need to decrease the nicotine level I am currently using.
So what Yihi is basically saying, is that by setting the joules (aka wattage) you are setting for consumption rather than power. Decreased wattage (or to them joules) would then = to decreased consumption and vice versa.
According to Yihi themselves, the emperor has no clothes, they have simply replaced wattage with joules to sound fancy so you can do your own calculation concerning consumption and make that your focus rather than watts.
Make sense what I was talking about? Read what Yihi said again, and this is what I am talking about.
@Opinionated... I think I've already explained this, and I don't want to be talking past each other, in circles. Let me try one more time...
I am referring to the PBusardo interview, where at 46:45 he puts up a screen shot of some Yihi web documentation. I assume you are doing the same. Now, Yihi is absolutely correct that, over the course of time, Joules is a better measure of juice consumption than watts and they explain why. If you set your mod (any mod) to VW mode, at 50W, and take 1 second draws, that will consume juice at roughly the same rate as if you had set it at 25W and did 2s draws. Not exactly the same because in both cases you have a power up time to heat the coil, but lets simplify and ignore that so we don't get lost in the minutia.
To do that they give you a Jules counter, which integrates watts x time. So at the end of the day, for example, you know how many Joules you expended. If you also knew how much juice you used up, you should be able to correlate so many Joules per ml of juice.
As far as I know, there is no debate or disagreement with the above (the functionality of the joules Counter). it is what it is and Yihi explains it reasonably well.
Where it all falls apart is the
Joules Setting in TC mode. As best I understand it (or anyone else as far as I know), the only thing the Joules setting does is to set the power to the coil until the point where it reaches the temperature you also set in TC mode. And it specifies (as far as I know) the
wattage, not the Joules. If you set a Yihi to 50J it fires at 50W until you reach your specified temp. Then it throttles back to whatever wattage it requires to maintain that temp.
Once the mod determines that the specified temp is reached, the Joules setting no longer affects the operation of the mod through the remaining course of the draw. UNLESS, for some reason, the temp dropped so drastically that it needed to "give it all she's got Scotty" for some brief interval before it again hit the specified temp and then needs to throttle back.
When I set my Evic-VT to 500F and 60W, and fire it without drawing on the mouthpiece (so I can watch the display) it very quickly drops to less than 10W (5-6W range typically). The throttle back is HUGE, and I can only assume would be the same on a Yihi M Class if I used the same coil build. I have never tried to read it in front of a mirror like some people do. OK, the stuff I do to support a post... I stood in front of the mirror, and it did basically the same thing, just spent more time at 10W until it dropped to about 5W.
It is critical to understand that when you set 50J, you are setting 50
Watts. In practice, on my Evic-VT in TC mode, I would guess that the set original wattage lasts about 1/5S at most.Maybe a half second? it's so fast it is hard to tell. If you take a subsequent hit within, say, 10s or so, it will not fire at full temp at all. It goes "immediately" into a temp throttled mode because the coil is still hot.
So... when you fire a Yihi in temp mode, set to 50J and whatever temp, it is (or should be!) integrating the actual wattage used at each instant in time (at the millisecond level?), and incrementing the Joules Counter accordingly. If you fire it for 5s, set to 50J, it will not or should not increment the Joules counter for 250J. It will increment some far smaller value, reflecting the fact that most of the time (certainly with a 5s draw) it is firing at far lower than 50W, likely 10W or less for a 5S draw.
I went through that just to try to make sure you understand what the mod is doing in TC mode, and what the two settings do. It is also important to understand that at a fundamental level, all TC mods have to be doing the same thing. Any differences would be related to how quickly they can adjust the power to prevent overshooting your specified temp, or allowing to drop. There are also differences that result in some TC mods "rattlesnaking" while some do not, but that is all just in the details of how they modulate the power. Fundamentally, they have to fire at a certain wattage to get you to your desired temp, and then they must throttle back to try to maintain that temp as best possible.
Yihi has done a great job obfuscating all this. Especially on that page that PB read and displayed. As evidenced by all this back and forth we are doing because you are focused on some nonexistent secret sauce. They say they are doing things differently than other TC mods. But the only thing they are doing differently is giving you a Joules Counter for eye candy. And the Joules Counter is eye candy. How many Joules of energy you consumed is an interesting statistic but it is quite meaningless in terms of how you set the mod to get the vape you want. At best the Joules Counter might help you estimate in advance how much juice you would consume on a daily or hourly basis after changing the settings. But I'm being very kind there, because in fact the amount of juice you consume, and the amount of Joules expended are 90-99% determined by the temperature you set, not the Joules. Because the mod only fires at the Joules value you set for a small fraction of a second. If, for example, you change your temp from 400F --> 500F I guess that would imply a 25% increase in Joules expended and juice consumed but that is just speculation. ETA: that sort of assumes ambient temp of 0F, I'm trying to simplify things here, it would not be 25% IRL.
So... for example, if you set your mod to 500F temp, and set it to 50J you will consume a certain amount of juice. If you then lower the Joules setting, the only thing that will change is that it will take a little longer for TC to kick in. If you set it too low you may never reach your temp, but that is sort of a user error thing. So if you reduced the Joules setting from 50J to 25J you would NOT cut your consumption in half. You might cut it 10% (just a WAG on my part because there is no easy way to estimate that without a lot of instrumentation or perhaps the data recording of a DNA200 chip can do that?).
There is actually no reason to set the Joules value less than max UNLESS you were getting dry hits and suspecting that the mod was actually overshooting your set temp. And as I think I mentioned previously, that is a very theoretical idea. I don't recall anyone actually reporting that? But I did not read the entire 400+ pg Mini M thread.
I hope this helps I am not perpetuating this talking past each other thing
And tl;dr: if you want to modify your juice consumption you will change the temp setting. Not the Joules settings. Changing Joules might not change your consumption at all! Changing temp absolutely will, assuming your draw time remains constant.
