Can you post a screen shot from device monitor of you taking a vape so we can see what the wattage is doing?

Brick sort of. I have bricked mine twice with a paused firmware update. Each time it was recoverable. There are a few threads about the process, but the front loader portion of the chip has a fall back interface for recovery.

Can you give an example of a device you have used at the same wattage that gave different flavor?

I am curious what make you conclude that escribe is not taking the curve file. Selecting a profile, then loading the TCR curve to that profile, then saving that profile to the device should work without a device reboot. Once you are vaping in that profile, is it then you feel a need to reboot? What typically happens is that once in a TCR profile, if the TCR value the chip sees is lower than that specified, it will go into non TC mode. A reboot will only get it to re-read the resistance and re-calculate the observed TCR of the wire installed. I suggest you run atomizer analyzer with a short between your coil posts to see what resistance your atomizer is adding to the mix. 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.

I still would not rule out the atomizer...I would test with some known good ones. Many have high resistance variation that make them poor for TC use.

So after factoring in an extra .008 resistance for the mod, it vapes well. That seems a bit high and if you can stand to have it service, I would. I bet there is an issue with the 510, assuming the atomizer is solid you tested with.

1. If you have an inferior quality atomizer that will cause resistance variations, you should not complain about TC mode. Fix your atomizer first. 2. If you need technical assistance downloading a .csv file from a website to put a curve into Escribe...work on the core concept of files and programs. Use a browser (Chrome) that will let you work with files in a user directed fashion. Think about saving the csv file to a location that matters to you, opening it with another program (Escribe in this case) and get accustomed to the concept of files.

Atomizers with variable resistance will be a nightmare. I have six GT's. Two are a PITA. Four are solid. I have moved to the Aromamizer...always solid. If your atomizer has variable resistance enough to through off the calculation, then use ohms lock after putting on a new build or replace it. I and a good friend of mine have trashed at least 10 GTs and 5 GT2s because they can't work with TC mods. TLDR: The chip requires a stable atomizer. Get one.

For me the best solution is VirtualBox for pre El Capitan or VM fusion for El Capitan.

You can download earlier firmware from this thread: /topic/66731-topic/?do=findComment&comment=900118

I bet the 510 wiring is suspect.

Any more details on the failure? Did you look at them in escribe? I have used Ni with 200 watt preheat constantly in two mods.

Thanks. Saves me the time. I was tempted to update to El Capitan over the long weekend coming up and test out VB 5.0.10, assuming it was possibly the fix. VM fusion appears to be the only option for the moment.

I suggest you run atomizer analyzer and short the posts of your atomizer with something handy, like a screwdriver or similar so we can tell what you base resistance is.

So you go to this site: http://www.steam-engine.org/wirewiz.asp# Select the wire you have (Ti in this example), select DNA200 to get the download link and then click the "Download TFR Table as CSV" ...and then you get what exact error?

So, for your Ni profile, Temperature Off is NOT checked, Coil material is selected as Nickel 200, and you are CERTAIN you are using Ni wire. At that point, I would verify that you don't have stray resistance in your atomizer or 510 connection (there is a good ground to the 510). One of the following is likely: Your wire is not NiYour 510/atomizer has a high base resistance that makes the small change in resistance in the wire not trigger TC modeYour chip needs to be replaced

Same day reply to RMA form, and turn around of part within a week.

Can you get more specifics about the issue? Where are you getting the file, how you are loading it and what error you get? Also, what version of escribe are you running as there was a conflict in number format in earlier versions.

Can you give an example of a build that won't work in TC mode? What wire, starting resistance and atomizer? Typically TC mode failure is usually the 510 connection or atomizer. Though it has been stated many times on this forum, if your 510, its associated wiring or your atomizer has a substantial initial resistance, and your build is very low resistance, then the change in resistance the mod sees will be small as a percentage and therefore it will assume the wire is non-TC wire.

Updated.

If there was no short, and no stuck switch, then send it in for replacement.

Ask KTMRider about Hana...I don't think they have the customer service staff or process to handle the issues they are getting.

I think it is time to open sub boards for each DNA200 mod out there so common issues to those mods may be identified or grouped. This would mean a parent thread for Vendor Mods, then sub threads for each mod. Just a suggestion. Right now, all the "I have ABC mod it it is doing 123" are pooling up in "report a bug".

The 200 will reveal fluctuations in atomizer resistance, especially with low resistance builds. I have found the new Aromamizer is amazingly stable. 20% of the atomizers I have tried are really unsuitable to high end temperature control.

Any wire that can have a predictable/measurable curve can be used. The resistance shift band on SS seems very small. I have some but have not tested it yet. It may be possible (say DNA200v2) to have the chip test a wire build and calculate the curve, then estimate where that falls on a temperature scale. Once there is a massive amount of data collected from DNA200 usage, curves and temperature the corpus of data will be there to initiate such a design.
