    hallo,

    On my old alien mod it's possible that the mod ask if you want the old or new ohm value if you re-detect atomizer in vw (Watt mode) can we get this on the cuboid..or is it all ready there and i missed it..?

    With kind regards

    Hello,

    What you want to achieve with this kind of message?
    VW mode is using real time coil resistance which is changing during firing.

    Yes, I know that this real time resistance will change..I attached a shot to explain..still not sure if it's nice to must change every time the Watt because sometimes the ohm simply change to a other value

    Why we should change output power? :) Output voltage should be changed on resistance change, but box do it itself depending on resistance measuring.

    I mean sometimes i still want to have the old value.. not sure if it's a stupid newbie thing or not ?!?

    It is critical for TC modes, when ambient temperature may vary in wide range, or something else... 'cause computation of coil temperature is based on difference between resistance in cold and warm state.
    But in simple VW mode it is totally useless, because resistance measuring manages output voltage in real time while firing.

    I don't understand this wish, really. You are using VW, not TC, as i told earlier VW using real time resistance to adjust voltage which will be given to the atty.
    The power will be kept correct throughout firing, regardless of how the resistance changes.
