If you look at the last Device Monitor screenshot you posted, you will see that your cold ohms were at .203 & when you fired it, the ohms dropped...to the true cold ohms... and slowly rose back up to the .203 ohms again...meaning that your cold ohms in the device were actually set at the hot(max) ohms...you need to get the correct cold ohms into the device, because the device needs to see a rise in resistance that equates to 185f temp rise...with the cold ohms set so high, its never gonna see it...you can try leaving the setup alone for a little while & let the refinement reset the ohms....or remove the atty from the device for a little bit & when you reinstall it, if it ask if it is a new coil, select yes... the coils HAVE to be cold in order to get an accurate reading of the cold ohms

Well, that's part of my issue. Those coils SHOULD be right around 0.21. This problem has been ongoing for a few days and I have left the device and atty alone for hours and it may or may not ask me if there is a new coil. If it does ask me and I select yes, shortly after it will go back to only firing at 1-10w's, like it using the wrong temperatures.

Where are you getting .21 from?

Edit: are you using spaced or contact coils?

I was looking over your screen shots & notice that you are using the Advanced User Interface...have you done any calibrations on the device yet?  Go to 'Options>User Interface' & select 'Manufacturer' & then post another screenshot of your Mod tab... I don't think LV sends out those mods with the 'Mod Resistance' set & it is really important for proper TC...

I hate to bump, but this thing is still not staying in tc mode. Sometimes tc works well for a hour or so and then stops using tc mode. Sometimes it senses the wrong temps and think it's 600F+ and only using 1-2watts. This is becoming quite annoying and I'd like to solve the issue.

Curious...have you tried a different coil setup besides the one you have been having issues with?

Yea, I only have 336L and kanthal so I haven't tried any other TC materials. I've tried 3-4 different SS316L single strand dual coil builds and 1-2 SS316L twisted builds. All 24 gauge.

Have you performed a mod resistance test on the device yet? After looking at your 'Mod' tab & a few of my Lost Vape factory files, it looks like they are using the same .ecig file on all their 75 devices...my 75's mod resistances (after testing) came out to .003..that setting is really important for proper TC....

Edit: In that last screenshot, your live & cold ohms are almost the same...not gonna work in TC

You are also going to need to run the case analyzer to get the correct case thermal values...the ones in your device are the Evolv default values...

It seems to read the wrong temps. The last screenshot is a fresh SS316L 24g, 3mm ID, 8 wrap twisted dual coil on my OBS Engine.

How can I do a resistance test?
