Thanks VegaBob, got the device and worked perfectly. Lavabox is at 0.003 and set to 80%(0.0024) Seems to be working much better. Running at 420F at 27W and getting a much smoother vape. Single 32G Nickle at .16ohm spaced coil on a Velocity Preheat 80w Punch 11 Time .5s

I agree with mactavish. PM sent.

The link for DNA200ThemeImageGenV1.1.02 in the OP (Post 1) is broken The link to DNA200ThemeImageGenV1.1.02 is actually the .02 part of that link. The link on the site where it is mirrored on points to an older version. Nice software though, thanks for sharing.

I did not run this twice, but new numbers This one is probably a bit more accurate I started it with about 45% battery Ran at 82*F Room Temp CASE COOLING TIME CONSTANT: 1521.32 ,,, but this was rounded down to 1000 CASE HEATING TIME CONSTANT: 753.92 CASE USB CHANGE TEMPERATURE RISE: 1.32 F 16.71 F/A

Well, I have always been on the fence about Ti wire. Have SS430 on order from UnkamenSupplies. We will see how this works out. So far, the Lavabox is giving me very noticeable smooth vapes over my other mods on my Kanthal Dual Clapton builds. Impressively smooth.

Yes, I did, and many others Thanks I will share my Lavabox Welcome screen that second one i am still working on

Your right, and it makes more sense now. It was my (and many others) lack of understanding Temp Coefficients of Resistance. So, the TFR could still be off a bit. But is it significant enough to matter? I know this coil has a cold ohm of .23 the atty itself is .013 the mod is, according to Volcano, 0.007, I should retest this though trying the copper rod method i will case analyze this mod when i deplete the battery about 60%. i changed the mod res back to 0.007 where do I put the off set .013 for the atty resistance? locking the ohms at .23 right now I have to push it to 530° or so, to fire it. it's a bit hot Can the TFR be modified to compensate? How do we go about keeping cotton from singeing at too high temps when we hit dry coil? Thanks for helping.

I really am trying to understand what is going on here. I don't like throwing around allegations of bugs. I'm a veteran tech, I know what I am talking about when it comes to such things. However, I did and I think I might be wrong, maybe. I was wrong about the Reboots. The issue there is, I was warming the coil enough to hit the minimum resistance to get a proper fire for a bit. Till it cooled again and then misfire at low resistance. Blueridgedog and Vaping Bad are more on track I think. I think the TFR is wrong for this wire, OR there is an overall issue with firing at such a low resistance in general. But I see others hitting .14 etc. Note, when it is misfiring, it doesn't matter what the Watts, Temp I set are. It will continue to do so. I also notice now that it is doing the same under a Nickle Profile. So I was wrong about that as well. https://youtu.be/G_a_z__72cg 1.) No, it's not the juice. 2.) No, it's not a dry coil, or Air Flow issue. It's an, it won't fire under .30ohm issue. That should not be an issue. So really, Profile does not matter. TFR doesn't seem to matter. Firmware version doesn't seem to matter. Setting MOD Res doesn't matter Overall Temp of the Case doesn't matter As long as it is locked at .30ohm, it will fire and TC as it should. Need to figure out where to go from here. BTW, my IPV3 Li and Sigelei 150W TC's handle this build just fine at it's cold ohm setting of around 0.23ohm.

I make my own juices. They are 20/80VG. I don't know the exact reasons for misfire, but it had something to do with the mod not reading ohms law or something and misfiring. It's right there in the screenshot of Bad Fire I posted. Then you can see the good fire shots I posted. It's still firing proper now with ohms locked at .30. I have more testing to do.

It's UnkamenSupplies 24G Wire, But I also have 26G and both act the same way. I have also set the Mod Res to 0 and most of the time it has been at 0 But results are no different at the .007 or 0. Trying .004 Also, the coil is not dry. It should be doing something more and does with juice on it when it's working correctly. So the air flow thing is not it. I know what you all are saying about Airflow, but that should only be the case with a dry coil. It should be doing something, but it doesn't do anything. Watch the video again, there should be a plum of vapor when it hits the preheat, there is nothing at all. You can't go lower than 200*F Anything lower than about 270 and there is no flavor at all. ***************some time later********** I did Contact Coils this time Set the Mod Resistance to 0.005 The reason is, in the Pic that I took of the Atty Analyzer, you will see the Nominal Temp Res is 0.006 80% of that is 0.0048 rounded to 0.005 I vaped on this a bit and it is working, after, again, a couple of soft reboots and re-uploads. But, here is the other part, and I am still testing, cause it was working, then after sitting for a bit, it stopped and was acting up again But I realized that my ohms were not locked. I have to Lock the ohms. In my case. and without much real math, and a lot of guessing. Cold Raw Ohm coil is about .24, But with the Atty itself figured in, and it being 0.013 ohm and take into account some possible other resistances, not including, or maybe including Mod Resistance. and some rounding, Locked Ohms at 0.30. I know, that statement makes no sense. Common Core anyone? But looking again at the Atty Analyzer of a Cold Coil It's reading 0.23Ohm for Nominal Temp So, that is a .07 difference Even tough I set it to .005 I really don't get it. But for now it seems stable. I am hitting right around 275*F at 22W on a .24Ohm (Locked at .30ohm) contact coil of Ti 26g , 8Wrap , 2.5mm ID Set your Temp 10 to 15* higher than what you expect to vape at Set your Watts to just under what you expect to vape at Preheat Power 100W Preheat Punch is 11 Preheat Time Limit 0.5s See Screenshots Attached. If you are still struggling with Ti Wire, this is the formula more or less. I appreciate everyone's posts and comments. They didn't fall on deaf ears. And this isn't done yet. we will see how this goes. I will be back to tell you.

I had set mod resistance for 0.007 according Lavabox site. But produced same results. I will test some more. http://www.volcanoecigs.com/blog/evolv-escribe-use-with-the-lavabox-dna-200.html?utm_source=EmailDirect.com&utm_medium=Email&utm_campaign=LAVABOX+DNA+200

I have to say, this is where the IPV3 Li actually has a huge advantage over most others. They support Ti and it seems to be pretty proper, I can set it and it works. Dry Hot (Temp Protect) kicks in and stops firing. Get the Resistance set proper and it just works. I understand this is a hobbist device that is not plug and play. But let's get real here, " If you have a significant amount of atomizer resistance, then it could push the total resistance to a point where they small TCR change in your wire is not sufficient to trigger TC mode. Without the base resistance of your atomizer, and having that value keyed into escribe, lower TCR wires like Ti will be hard to use, especially if your atomizer has a high base resistance. It will be impossible if your atomizer has a significant amount of variable resistance." Then this is a HUGE flaw in the design. But, this is also not the case, TC Mode is kicking in. The DNA 200 just doesn't know how to handle Custom TFR.

Note: After posting this and letting the DNA 200 sit for a few minutes, it is doing it again. Low Watt Temp Protect. nothing changed from my last vape when it was working. Other than the case cooled.Tried doing a soft reboot, and nothing, same issue, Switch to a Nickle Profile, no issues. This is without a doubt a custom TFR issue. 1.035.2 (FW: 2015-09-30.sw-update) Thank you for replying. But I'm not buying it. The Mod works all day long on Ni200 for Coil Material But as soon as I load a Custom TFR/TCR it goes all wonky on that profile I can run my atty's in Ni200 profile, at 100W +/- less, like most mods that don't support Ti, it works all day long. This has ZERO to do with not detecting Temp Mode. Cause it hits Temp Protect. Not gonna hit Temp Protect if it is not detecting Temp Control. I have tried Steam Engine Ti Grade 1 and Grade 2 And I did it again. and it took a Soft Reset of the device to get the Profile to start working And it is working as it should. Profile 1, Load CSV Upload Settings to Device Hit the fire button Settings go all Wonky https://www.youtube.com/watch?v=9Im2LUY3MPY Soft Reset the device and everything works. Sometimes it takes a few re-uploads and resets to get it to work. This is why I am thinking that the DNA 200 is not loading/reading Custom TFR files properly. While I was actually using it, it went into Low Watt Temp Protect. This is what I am calling it. It sticks around 10 Watts and hits Temp Protect and produces no vapor at all. This is a bug in Custom TFR. Cause it does not do this when using Nickle Profile. Evolv needs to build a default Ti Coil Material Profile and fix Custom TFR. However, I am willing to figure out what it takes to make it work properly, efficiently and stable with Ti. I just don't think we can do this. It's in the Firmware/Software. more than likely the Firmware. One thing that this still needs is for it to cut off power completely when it actually hits Temp Protect. it doesn't do this. it needs to treat it like a Dry Coil. Hit Temp Protect and it stops firing till you release the fire button. I uderstand what Temp Protect is doing. And you want to bring your Watts down to just under where your Temp maxes out. This is all fine, but it should cut power when it hits Temp Protect, cause this is more about stopping Cotton Singe and possible over heat of the coil. I know it stops for a moment till it cools and if you keep firing it will hold that temp and keep cutting out. but it is slightly inefficient way of doing it. This is what I believe the Yihi Chips do. I am still on the fence about Ti anyway, and won't do Nickle. Bottom line, from everything that I am seeing, the DNA 200 does not handle Custom TFR very well at this time. Side Note:

NOTE: As a tech, I hate when people throw the word bug around. And I just found myself guilty of it. My apologies to Evolv for my bone headedness and lack of understanding. Let this thread be a lesson to anyone that feels such urge out of frustration to do the same, in life, in general. Also note, that, Ti setups are not as tedious or finicky as they might seem to be at first. If you are new to TC and just looking around here, or interested in the DNA 200. Read this thread. Believe me, you will learn something, just as I did. ***************************** There are a lot of bugs that need to be worked out of the DNA 200 Especially when it comes to Ti Wire and custom TCR files Either it is the DNA 200 or the Lavabox I am not entirely sure. But, I have to assume it is the DNA 200 itself. TCR files for custom Wire does not upload properly. It can take several soft and hard reboots to get the DNA 200 to recognize and work properly with a custom TCR file. It will sit there and clock around under 10W and then hit Temp Protect I have gotten it to work, but again, after several reboots, resets, re-uploading, switch profiles and then it will start working. This is not a build or RDA issue. Tobecco Velocity and a Hellboy clones both act the same way. Single coil spaced, both 26Ga and 24Ga. I finally figured out Preheat settings and not to over do them or you will get glowing coils. So, before anyone starts throwing around, "It's your Atty/Build", I promise you it isn't. So, my request is for Evolv to work more on fixing bugs in the software and the firmware. They need it desperately. This is in both 1.0.32 (FW: 2015-08-21.sw-update) 1.035.2 (FW: 2015-09-30.sw-update) They both act the same way. Again, not the build or the atty when I can get them both to work after many resets, reboots, re-uploads, switching profiles between custom and default Nickle Profiles of the same settings file, only then does it take effect and start working. Thanks.

I ran the test at 75*F According to Atomizer Analyzer the Room Temp was 76*F However, this test may be inaccurate. I ran it when it was almost fully charged I will run it again when it is about half charge. The test took about 2.5 to 3 hours. Also note, I Loaded the CSV Battery file from here And I also set these Battery Capacity: 9.99Wh Soft Cell Cutoff: 3.09v Mod Internal Resistance: 0.007 Ohms Based on what I am seeing and from others posting their results for other mods. It's hard to say how accurate the Case Analyzer actually is. Room Temp, if this is not constant everywhere you decide to vape and charge, these numbers very well could change This could cause big fluctuations. Right now, my Room temp from Atomizer Analyzer shows 65*F, but, I am in the same room I was in when I ran it the first time. Yes, I believe that Temp is correct though. it is colder in here than when I ran it before. I will run it 2 more times, and I will check both the Atomizer Analyzer and a Thermometer in this room and average the temp from that to run at. Also, the next tests will be run at half charge, and the mod will sit in this room pretty much over night and then run the test. If the results are drastically different, then I could only surmise that Case Analyzer may be kinda useless, as these settings can change based on the actual temp of the mod at any given time Such as, you have it in your pocket, it's gonna heat up a bit, so, where the Analyzer and Thermal settings were set based on a Mod Temp of 70*F, you might be running it at a temp of 85*F How this takes into account settings based on Case Temps and Ambient Temps at any given time, I don't see how this could stay accurate. CASE COOLING TIME CONSTANT: 1623.94 ,,, but this was rounded down to 1000 CASE HEATING TIME CONSTANT: 170.19 CASE USB CHANGE TEMPERATURE RISE: 0.71 F 28.00 F/A
