Your probably right.
All my 5 DNA's 75C are updated. The problem is the lack of themes to make use of the function. The only one that exists does not allow to adjust the wattage nor the temperature.
I do hope Daniel (DJLsbVapes) can manage the time to update his theme (for me the best).

Checkout my Enhanced Default DNA 75/250C theme that is posted; for international firmware, it allows both boost and preheat, depending on whether the profile is set to wattage or temp mode, and allows adjustment of the punch. Also fully updated for Replay.

In my experience, the battery profile curve will affect the fully-charged upper voltage reading. Not an actual performance issue, but we want the voltage and percentage to show correctly; best bet is to run your own battery analysis while the battery is pretty new, or download one that matches your exact battery.

First Mirage - mod resistance set to 0.01 Ohm. Second (yes - I like the mod) was set to 0.004. Anyone know what it should be set to?
First mod - no mention of Replay. Second one (received last week) mentions Replay in the instructions and on the box. However no sign of it . Will have to wait for the update ...
0.01 ohm is definitely incorrect; far too high for internal resistance. I measured 0.004 with a copper plug and set it to 80% of that, or 0.0032. You can use that value as a safe measure on both mods if you don’t own a plug to take your own measure.

Thank you so much! Is there any way I can set the boost time?
I don't believe so; if I remember correctly, the early betas of Boost allowed wattage and time to be specified; however, the latest iteration condenses these into the Punch factor. I'm assuming punch is an aggregate measure of power plus time, on a scale of 1 to 11. Don't quote me on this though

SP12 is the Escribe version, which is the latest beta for the 75C (there is a v13, but it’s only has updates for the 250C)
SP27 is indeed the latest beta firmware for the 75C.
Concerning boost, make sure you’re in wattage mode, enable boost, and set the punch to a value between 1 and 11, preferably around 7 for testing. Take a puff and check the monitor; you should see a spike. Note that your wattage will need to be somewhere below 75 to see a boost, or you can check that the maximum output wattage is set to 100 in Escribe to boost past 75W.

About 10k puffs into a Mirage 75C; really great mod. The finish is top-notch, and love the resin and low weight. Single battery doesn't pack as much punch as dual, but you can get a good 2x700 battery with a high mAh rating. Only issue with the mod is the battery door: I dropped mine and the door split open. It's held together by double-stick tape and two tiny plastic clips. Removed the sticky tape and used epoxy to reseal it, and it's good as new, if not better. Well worth it!

EScribe battery profile CSV for the iJoy 21700 3750 mAh 40A battery. Couldn't find this anywhere so went ahead and ran the analyzer to create it; hope it helps!
For reference, this battery came in right at 10.575 Wh. Per Mooch's tests, recommended maximum sustained input current of 24A, maximum peak input current of 40A, and a cell soft cutoff at or above 2.75V.

@JohnI'm assuming there are two versions for legal reasons, but it would be nice to know if there are any downsides to installing the international version on a USA Mac computer. If not, then is it ok, to simply overwrite the US version I currently have installed?
Confirmed that upgrade to the international Windows Escribe version and v2.0 SP6 firmware has been running for several days without issue. Loving the boost functionality as well1

I changed it to 10 and it still moves at 0.1 not sure if I'm doing something wrong or is it my vapedroid.
Be sure that the field Source is Coil Temperature. Click Options, and set the Step Size to the desired increment:
Hit OK, and be sure to Apply the theme, and upload the changes to your mod.

You can use the theme editor to select the wattage text field. Modify it and you can then change the increment.

Peraspera, you can use the Therion out of the box, but earlier versions did come uncofigured at default settings. If you’re going to use Ni or Ti, the safe bet would be to review the material and Mod tab settings in Escribe first. If you only have a Mac, you could run Escribe in a virtual environment. I posted a fully configured Therion settings file to the download section of the forum as a starting point for mod safety limits if need be. As far as firmware goes, the stock firmware is fine, though I’d recommend the beta from the “ohms too low” thread, as it helps to correct the resistance measurement which is needed for accurate temp control.

@James I've had a day with the beta and performance is definitely much better. Tested two single coil builds against my two DNA250 mods and the beta DNA75C, and the resistance readings are spot on. This with 0.004 internal mod resistance as measured, and the 250's set with their own respective internal resistance.
I did some testing with room temp, and believe that the 75C only seems to update room temp after the mod goes to sleep, or after a reboot. This explains the big jumps I'd mentioned earlier: I'd watch room temp sit at 73 degrees, vape a bit and then let it sleep, with room temp never changing. Picking the mod up ten minutes later then showed a refresh, which would bring room temp way up, as obviously the mod is much warmer after having been used recently. I tried the default profile's thermal settings, but room temp is way off when cold; I decided to instead stay with my results averaged with @ndb's results, and room temp is pretty close to actual when the mod is truly cold. I think what also helped a lot is reducing min and max room temp to a narrower band, 60-90 degrees. Note that after vaping a bit, room temp will always hit the max ambient 90 degrees if I let the mod sleep or do a soft reboot. However, the vape has still been very good, having left the cold ohm reading when the mod was actually cold and room temp was true.
So, much, much happier so far with the DNA75C running the beta firmware! Will try another build this evening and will update if anything weird happens.
Key settings for reference if anyone else wants to try the beta and wants a reference point:
SS316L: Curve set at Stem Engine CSV curve
Therion internal mod resistance: 0.004
Case thermals earlier in this thread
Min ambient of 60, max ambient of 90

James,
Trying out the provided v1.1.SP22 Beta 1 service pack. Cold ohm reading jumped 0.013 ohms on the first coil tried, and the vape is definitely better. Had to drop TCR for SS316L down from Daniel's 0.001 to 0.00094 to keep from a burnt taste. I'm wording what is new in this firmware release? Was an offset entered in firmware, or something else? Should we be dropping our TCR back down to published resistivity for stainless?
On another note, I've experienced over the last few days that the 75C's cold ohm reading and quality of vape in TC mode greatly depends on the associated room temp reading on the board when the cold ohms were measured. The problem is that I've seen the Therion room temp reading vary greatly, from 65 degF all the way to 88 degF, even when sitting still in a level 73 degF room. I've taken to reading cold ohms, then manually setting the recorded room temp to whatever the board happens to be showing as room temp at the time to get it consistent. Any ideas on this?
Thanks for the beta firmware and input!

Shinn,
I experienced the same issues as you at first. The Therion comes with default reference settings unfortunately, which means it basically needs to be fully configured before it will give you a good vape. To start, you need to run the Case Analyzer. Set the mod on a table, make sure batteries are about a quarter to a half charged, try to measure the surrounding temp, and let the analyzer run. Be sure to upgrade to the latest version of Escrive first to make sure you don't get an error when you upload the settings. You can optionally attach an atomizer to better represent the full thermal dynamics as when you vape.
That will greatly fix the cold resistance readings and room temp reading. I'd also recommend manually re-reading cold ohms every time your atomizer is cold; this is what the other DNA chips do, and wish the 75C did.
There are many more settings to configure, such as input and output currents, battery profile, internal resistance etc; I actually just posted a copy of my Escribe settings for this mod, fully configured, to the downloads section of the forum; once approved, take a look for some of these settings in my file if need be. If you'd like a copy now, just let me know. Hope this helps!

Ran the case analyzer last night and the resistance measurement is much better. Only tested one build, but the cold resistance now matches what the DNA 250 reads, and the vape is great. I hit the same error in trying to upload right after the analyzer finished, so I just screenshotted the results, restarted Escribe, and plugged in the values by hand which then worked.

I have to say that I'm experiencing the exact same thing, though not as drastic as several tenths of an ohm off. My DNA 250 mods are dead-on when reading cold ohms. I've taken the tank and build directly to the Therion 75C, waited for it to cool, and the cold ohms reading is far too low; around 0.02 ohms off, which makes the vape negligible. I have to manually increase the cold ohms to get it where it needs to be. From what I can tell, the 75C is different from the other boards in that I think it's compensating the cold resistance by the ambient room temp. That being said however, the room temp reading on the mod is way off; 10 degF or greater.
Wintergreen, would you mind sharing the results of your case thermal analysis? Has your experience gotten any better on reading cold ohms after running the case analyzer?

Unfortunately I didn't take pictures when I had the door apart. Essentially, the Mirage door is metal on the outside, with plastic on the inside held with two tiny plastic clips and some 3M sticky tape. I have two Mirage mods, both of which have failed; the door on each has popped open, as all of the weight of the battery is on the two plastic tabs that aren't anywhere nearly strong enough to support the weight. This in my opinion is a design defect, and I'd suspect that most of these mods will break in this way over time.
My fix was pretty simple: took apart the metal and plastic door, removed the tape, and applied a very strong epoxy. You have to be very careful, as too much epoxy will seal the door lock slider and the door will be useless. Overall it only takes a few minutes to loosen the two screws, remove the door and apply the epoxy. Compress it and let it set overnight, and you're back in business.
