Just in today! Temp control is spot on and the chip is SUPER fast as usual. Good materials and excellent build quality. Interesting temp control variations but I still don’t like the joystick navigation. The only thing the joystick does well is take up less space on the faceplate. Love the form factor. Glad to see YiHi is going back to their roots as they have not produced a new SL class in around six years. Highly recommended.
Update: the interesting thing is that you cannot just adjust voltage like a “normal” voltage override mode without the chip doing its calculation on the resistance of the current coil, the battery level and the average room temperature setting. They call it “Intelligent VV”, It appears to always give you the safest setting it thinks is best by leveraging battery efficiency. You cannot override the coil resistance sensitivity and of course the chip sensing the battery level. You can manually adjust the resistance and lock the resistance. With the few atty’s I have tried, the chip takes over the computation of what it thinks is best. I have yet to see more than 6V applied. It will reach 100W shown but always adjusts voltage to achieve that setting. Also, it appears that the curves function is always on, there is no bypass for curves. You either run flat or pick the levels of heat they have picked for you. Where this chip shines is in TC and speed. In TC mode you can go in and adjust voltage and temp but you cannot override the sensing to go over what it thinks is safe for the coil read. It also has an average room temp adjustment which I think also adds to its equation on safety. In other words they have broken down the settings for manually tweaking into 5 presets making the choices easier for the “average” user. Making safety as the top priority. You can go into EQ mod and adjust each line in a graph for a percentage of temperature but I doubt anyone will tweak at this level as it takes so much time to do this which each coil you attach. One other thing is the manual says in the Menu Tweaks menu, there is a setting for Auto Watt when in fact the menu reads Auto Power. This would indicate to me that the manual was written and printed before they made a firmware update. The manual does not mention what Auto Watt/Power is for and what it does. Still trying to figure that out. If anyone knows, please let me know.
