Thank you Vlad.
Its just that the only set up I've used for the last 11 months has been the squape running nickel on a DNA40 flask, vaping hard all day everyday. In that respect, its not my first rodeo & not with that atty in temp mode, however, when it comes to the YiHi chip, this definitely is my first time.
So yeah, I need to re-stabilize/reinforce my center pin which'll hopefully help.
I have found that the squape is stable despite what I explained & I realize that it shouldn't perform like that (i.e. center pin adjustments affecting resistance). However, once adjusted to a resistance/Ω rating, it is very consistent with whatever resistance its been set to. e.g. the resistance doesn't jump all over the place when using a DNA40 where the resistance is not locked-in like it is on the YiHi or the new manual Ω lock function on newer DNA40 chip sets. This shows that, despite being slightly adjustable for me via center pin, the resistance is at the same time consistent once its set & won't jump around like can be experienced when coil's legs aren't secured.
I check the expected ohm rating on steam engine and adjust accordingly for my resistance to match up to its expected ohm rating & go from there.
Of course, based on the same principal of allowing coils to sit for 10-15 mins to reach consistent room temperature & therefore accurately calibrate its resistance, the opposite is true where resistance increases when the coil is above room temp. Perhaps, my issue may come from repeated use/heating of the coil, the coil gets so hot it wants to increase resistance but with its ohms locked in, it reads that the coil is dry when it isn't. This is strange to me coming from temp control limitations of DNA40 being a limiting factor, whereas with the YiHi, the temp doesn't appear to come close to maxing out. It seems the SX350J instead limits it by thinking the coil's gone dry which might essentially be another term for a similar action occurring at the coil because a dry coil heats up faster than a wet one.
