Vlad, you are experiencing the exact same thing I am when in the Ti Profile. Same exact resulting Performance twitchiness. I have tried multiple Devices and Builds to eliminate those as the Root Cause too. Running 26 GA, 5/4 Wrap (spacing approx. a wire-width in between), using both a 7/64" (2.78mm) & a 3/32" (2.38mm) bit which after spring-back expansion due to natural Properties of partially annealed Ti ends up about 3mm & 2.6mm respectively. To each their own on that choice of Bits and final I.D. depending on Wicking and the Device preferences. However,,, that propensity of the Ti Wire must be taken into consideration in matching Steam Engine Calcs with what the SX shows. The final I.D. is not really the Bit or Mandrel wrapped on as is the Case with Kanthal. No Biggie none the less. Anyways,,, it always yields a Resistance of 0.23-0.24.
When run on Ti Profile, all Attys tried packing that same Build performed in a Jumpy and twitchy Manner with the Resulting Vapor being equally as varying but seemingly always lethargic. Running at the High Temps did improve the Vapor Qty but did not improve the Flavor. Furthermore, the twitchiness in Temp remained if not increased a tad. The above was not positively affected by any change in Joules Setting ranging from 17.5 up to 25.0
When I switched the exact same Attys, with exact same Builds, exact same Liquid over to the Ni200 Profile set at 17.5-20J & 300* F, Ta-Da! Very flavorful and cool-to-warm Vapor and it purred along steadily and unwaveringly.
Conclusion Theory, it has to be the Test Firmware as it exists and is functioning on my Device. Combine that with your same Results in very similar Situations, and that Theory & Conclusion are bolstered and further substantiated.
One probable Root Cause could be the Test Download and how it installed on our Devices. Much like a Program or App which runs great for some and with issues for others, a simple uninstall and reinstall can have success and then be all Peachey. Will have to try that when I get the chance. However since the Ti Builds, as described above, are performing marvelously on the Ni200 Profile (with appropriate and prudent tweaks to the Settings that are well known and practiced) I am still quite pleased and totally satisfied so have little motivation to go to the hassle and effort to do so. I will probably just wait till the Test Firmware Period is over and YiHi dials it in and releases the corrected and stable Version.
*This is NOT a damnation of the Device or running Ti on the SX Mini M as it currently exists. This is a Test Version and these Issues are to he expected. Actually, we all want every possible Quirk and Issue to arise. That's why they released it in the first place. Gotta know the Issues to discover the Cause so the lasting Solutions can be created and implemented along with other improvements such as more friendly and logical UI. This is how and why these Tests work and are needed.
Again, No Biggie and It's still all good.
2 legs; Ain't NOTHING wrong or problematic with Ti Wire (G-1 properly cleaned) or that obtained from Unkamen or any other Reputable & Proven Source for that matter. That is NOT the Problem here. Stop worrying about the Ti Boogie-Man. Relax. Remain Calm. All is Well.
This is nothing more than a Test doing exactly what it is supposed to do. For that and what it truly is, Success.
They will get it corrected and dialed in. When they do they will release the Final Ti Profile Version and all will truly be just Peachey in our little SX Corner of the Ti World.
Until that glorious Day when all is set Right,,,
I plan to keep on building and using Ti to run on the Ni200 Profile or using the 0.12 OCC Ni200 Coils on the STM and others will run the Ti Profile and love it Settings straight up or tweaked. And, It'll still be All Good.
