Why do I have to set my TCR to 470 for my Ti build to get a warm vape? 366 is anaemic. Or is 430°f supposed to be cool and anaemic? I have no reference because my other tc mods don't have adj tcr and underheat, so I'm told.
Here's the build and my res is locked at .10 ohms.

This atty is the Aromamizer and with the same build with kanthal I get great flavor and cloud production at 80w. With Ti not so great yet.

For my Ti builds I find I start at 470f, and depending on juice, go up to 520f. Wattage set to 35, gets me to "temp confirmation", very quickly. This on DNA200, Ti TCR set to .0036. A 0035 TCR is a bit cooler, tested on a new EVic VTC Mini as well.
With Ti, I'm in the 500-520° range using 30/70VG. Using NiFe, I'm around 480-500° and to me, the vape on both is barely warm, which is where I want it. Not near as warm as that mech I was testing your NETs out on the other day, lol.
Discovered part of the problem. One of my coil legs wasn't completely tight so one coil was firing harder than the other. Now reset TCR to 430 and temp 450°f. Wattage is up from 30w to 60w when reaching temp now. Also locked res at .11 where it should have been initially. Nice. I think I'm liking this whole dna200 thing.
new graph. TCR 0043 450f .11ohms dual 24g 7wrap 2.8mm Ti rockn at 60w on the Aromamizer. vapor is warm, not hot.
Funny how you can see the wick running out of juice real time.

Naaah, I changed the Time Scale in the Graph Options Menu to 10sec for better resolution. That's only a 2.04sec drag.
@cigatron I just got my Reuleaux DNA200 yesterday and started using it myself too. I also do think it is real cool to see the real time action on the graph. It really shows you much of what is going on. Along with some normal TC knowledge, experience coil building, and wicking, can be great info to even to deeper into the black hole of vaping. lol
I am running almost the exact same build on my Aromamizer with the exception of 2 more wraps and an expanded 2mm diameter coils. My resistance is at .103 also and 25PG/75VG. Ran it last night into the real time graphing and watching the results.
I am using the Steam Engine Ti profile unchanged, and find that 490F is giving me a slightly warm vape. About 20F more than that and I start to taste some metal. Using rayon for this build and have it stuffed tightly in the coils and cut so that it touches the deck with a little extra. No problem getting juice into the coils or anemic vapor.
I see that your power is in the mid 30's on the first graph and 60ish on the second. Your steam engine chart is showing 80w with a 286 heat flux which is I am sure what you are shooting for. If you change the SE to 60W it will go down to a cooler 215 HF, and at say 43W it is an even cooler 154 HF.
With my build I am running it at 60W and find that anything more does nothing much. 40W works too, but the ramp up is slightly slower. My wattage seems to be running around 25W or so when hitting temperature for my build. The difference seems to be our TCR settings. So the question is should we be true to the TCR written settings, or change the TCR value to make it vape the way we want it to vape?
My next build I will give your winding method a try using a 6-32 screw at 7 wraps but maybe go to 26ga which should bring up the HF. I think we are both looking for a HF somewhere in the 290ish area which is slightly warm but not too hot.Here are my results with my current Aromamizer build with a long draw:
You can see I almost hit temp immediately using a 120W preheat, 5 punch for 1 second. What I want is more utilization of my wattage to give more HF. My vapor production and flavor is excellent but just very slightly warm vape. I prefer it to be warmer. Last night I was doing lots of testing and even with 3mg NIC, I was dizzy from all the NIC taken in.
So would I be correct in stating that what we all want is a little more Heat Flux?
Yeah, I'm all about cheating if that's what it takes to get what I want...lol. In this case I was po'd that I couldn't vape my Aroma at 80w like I could with Kanthal without turning the temp up to 600. So I cheated and set my tcr for .0043. Still, I can only manage to get 60w out of my aroma before things warm up too much; hotter than kanthal.
The cloud production and flavor are still slightly down from my kanthal build at the same warmth level. Disappointing.
Perhaps it's the fact that that Ti has less heat capacity than kanthal but we know heat flux is based strictly on gauge and wire length right? So I expected with identical builds , KA1 vs Ti, the max wattage would be the same like it was in my STmini when I switched from KA1 to TI.
On heat flux you're right, I like designing coils that run HF close to 300 but they have to run there. In my case 80-85w which it isn't.
What has me scratching my head is how you're only getting 20-ish watts at 490f. It must be a very cool vape. If 20w is were you want be that cool but like you said, thinner higher heat flux wire would prolly perform better there. If you want to go higher in wattage you'll have to open up the afc and get in wicking faster. BTW, I'm using rayon too and wicking it up like you are.

Yes I am wondering too but it is a slightly warm vape and not too cool. It does produce lots of flavor and decent clouds too amazingly.
Now I will work on my 7 wrap 6-32 Ti builds on my new Zephyrus 2, Indulgence MT, and I will give a try to some verticals on my new Black Aromamizer. I will use Pima Cotton this time with all of them and we will see how those go. Maybe some comparison charts with the same 6-32 7 wrap windings using 26ga Ti instead of the 24ga going for a higher HF. I might even try a 26ga Ti twist with 32ga Kanthal A1 for the verticals on the Black Aromamizer. Probably a nice build for the Reuleaux with the extra power compared to my previous usage on my SXM which was a battery killer but produced nice vapor.
This is the best I can get from mine at the moment, twisted NiFe52 x 2, 2.7ish id, aromamizer

Long gradual curve to hit temperature. Looks like you need more power and preheat for that fairly low .075 ohm build. What size wire and number of wraps are you using? I need to get my hands on some real NiFe52 one day.This is the best I can get from mine at the moment, twisted NiFe52 x 2, 2.7ish id, aromamizer

I guess I forgot that part, twisted 26 gauge NiFe52, 6 1/2 wraps
Higher heat capacity, higher mass and lower heat flux than my 24g Ti. Probably equivalent to 22g Ti. I agree, needs more preheat power. Still, stable at 50-ish watts is good. Rayon wicking would probably help up your wattage, vapor and flavor, that is if you're not already using it.
Try bumping up the power to 100w and a preheat to 140w and see what that gives you. You still are barely reaching temp and slowly at that.Here I've bumped up the punch and preheat to 105 watts.
Or maybe keeping the preheat at 105 and just moving the wattage up to 80 or so. Too high on the power causes the temp to be unstable when reaching set temp in my experience. The idea is to use only enough preheat to get the coil up to temp quickly then only a little more wattage than it takes to keep it there. At least that's what I've found playn around today.
I have been a big proponent of only using enough power to achieve temp and not any more than needed otherwise you will be fighting TC. I learned that a long time ago with the SXM. But in his case with such a low ohm build and his curve badly underachieving TC he may need a big boost. But it is just a guess and he will need to find those magic numbers for his build. I think we all know what is the goal, but at this point it is only a guess to get there.
You do realize that your coil is hotter than 450°. Why are you playing with the TCR and locking in wrong resistances? I just don't understand your need for the mod to report back 450° instead of the real temperature.
I can calibrate my speedometer to read 20 MPH low. If I did I would enjoy driving around at 70 MPH, but the police will still pull me over for driving 90 MPH.
