FWIW...So just in case someone else runs into this....Think I figured it out. I was on a SX I Q Flavor mode. I’m not even sure what those settings are for tbh.
yea that's what a couple YouTube reviewers have said it's kinda a warning system of sorts that the wick is getting dry.kinda cool tho.FWIW...
I don't use TC, but believe I read that with the way the YiHi chip works, this pulsing can be more noticable when you set your wattage too high too. It hits the temp really quickly and causes more pulsing, especially when you first hit it with a cold coil.
Not sure, something to keep in mind though if you notice the pulsing even with it set in the correct mode.
Very weird. I tried another RDA on it and now it works fine. Didn’t like the Enthion clone or Recurve I guess. Not sure why both have spaced simple round wire at .7 ohms.
These high end devices are so finicky about stuff. I can put anything on the Revenger X and it’ll work and I get just as an enjoyable vape lol!!
Yihi uses Pulse Modulation to try and maintain temperature in TC. If you look at DJLsb’s measurements, the pulses get wider apart the dryer the wick gets

This is far more a factor if using factory SS coils using NR (nickel) legs. They induce their own TCR atop the coil's. However, in all but the most extreme cases the Yihi chips can accommodate this (and in 510 pins) with perhaps a slight tweak to the TCR if you want accurate temps. The regulation is still decently smooth. In extreme cases where it's not you can just bump the temp and run basically power mode but with dry-hit prevention still intact. Very capable chips!I second the fact that if a 510 pin is plated, the mod is unsuitable for TC.
Different metals creates a thermoelectric effect (Seebeck effect) that confuses the TC circuitry.
The pin must mandatorily be made of berillium-copper. Alternatively, brass can work if you clean it often from the oxidation.
Other materials make TC regulation very poor.
