eVic 1.2: Changing wattage changes voltage?

[sofauxboho]

On my eVic running firmware 1.2 in VW mode changing the wattage makes the voltage change, and changing the voltage makes the wattage change.

You can see this by holding the wheel "left" until it cycles to the screen that displays ohms and volts in little letters (while it VW mode) or ohms and watts (while in VV mode).

Is it supposed to do that? Is there any way to hold the voltage constant while adjusting watts? Or is VW just a fancy sort of VV where it does the math to figure out watts for you?

you got it! setting the wattage to one number then the voltage will adjust on the fly to whatever resistance you screw on the end to meet that setting

this is the idea behind VW you set one watt and the pv does the math for you to always achieve that setting. exciting isnt it?

Huh! So rather than just controlling something that influences the amount of energy going to the coil you're controlling the quantity of energy more directly, with the mod doing the math? That is pretty cool!

I take it this would correct for switching between different resistance attys?

Is there any advantage to VV mode, then?

They both do the same thing. In VV mode, it will automatically adjust the wattage and vice-versa. Put it in VV mode and adjust it up and down, you'll see the wattage changing along with it

Juices taste different at different wattages. VV preceded VW, allowing us to adjust the voltage to find the "sweet spot" for each juice, which, ultimately, was some number of watts that worked for us.

VW lets you directly set the watts, do if you use the same juice and, say, recoil at a different ohm value, the VW device doesn't care, it auto-magically adjusts the voltage for you to keep the same watts.

FYI the mod doesn't adjust the wattage to match the voltage (in VV mode) - physics does that

At the end of the day, they are both just a way of outputting a voltage you like. One makes you do math (VV), the other does the math for you (VW).
