Mine was working fine last night after the update, but all day today my ohm reading has been jumping around very many times from 1.33-2.20 ohms and half the time this is giving me a burnt hit cuz it's adjusting the voltage each time. Quite annoying
This is actually a known glitch that's been around since before the update. It's just now that you have an extra decimal place in the resistance readout that it's easier to notice. It's basically down to the resistance of your coils being too close to 0.15. It causes the resistance value on your iPV3 to get jumpy, especially on coils that have more mass. Earlier this evening, I built a dual coil that came in at 0.18 ohms and it's running just fine. My resistance reading wanders between 0.17 and 0.19 ohms (the temperature of my coils also factor into this) but it's vaping just fine.
And yeah, the 165 watt update was supposed to lower the usable resistance value to 0.08 ohms. Go figure.
