    please still using the latest bootloader and firmware above,

    Z100A-1.jpg
    this is version 1 noting to change hardware version

    2-2.jpg
    this is version 2 you need change hardware version to 1.01

    zoom picture above, see the user interface display

    nothing bad happen if you false choice hardware version, you can try first, if you have problem with display you can change hw version later.

    It seems that the maximum output voltage can not be higher than the total battery voltage.

    lostvape gruss/ursa and articfox work great buck boost converter fuction correctly, according to the specification limitation, which is 100 watts, if you want to use a maximum voltage of 7 volts (in 100w), then the wire resistance must be at 0.5 ohms, if it is below 0.5 ohms, the voltage will be limited by 100 watts, if it is above 0.5 ohms then the wattage will be limited by the voltage. of course there are other limitations such as cut out battery voltage, max current, etc. and now I understand why Articfox does a very soft start, if without a soft start the mod easly will trigger cut out low battery protection. but sometime i feel trigger low battery cut out more frequently with temperature control mode but in watttage mode everything is normal, i dont know why maybe just my feel because i dont have modified usb c for monitoring device :D so i use lowwer wattage for compensate it.

    If I understand these graph correctly, Grus is reading the resistance a little high until 0.5 Ohm.
    Voltage boost is working from about 0.5 Ohm and up.
    Somewhere before 1 Ohm, it can’t deliver anymore the voltage required. 2021-04-14.jpg
    I think the sweet spot is somewhere between 0.5-1 Ohm for optimum battery utilization.

    I got the v1 grus mod after seeing this thread . Amazing work done here
    can I do this if i have minimal knowledge and skill in soldering or am I gonna brick my mod? is there a video showing detailed steps of the whole process?

    I wanna add that i think this mod is not very accurate when reading resistance, it reads it lower than it should be
    also I feel like it it takes longer than aegis solo to heat the coil for the first puff
    sorry guys i'm not experienced and i dont know if these observation s are correct

    What about the Gemini? Pretty sure this uses the quest chipset as well.

    Nice to see this community coming together to make AF work on Lost Vape mods. Is it because people like Lost Vape or just like a challenge? Seems out of all the different brands making mods, I'm surprised to see enthusiasm for modding the Lost Vape Grus and Ursa, which seem very capable mods on their own, but I guess they aren't the DNA chipped mods from them, so I can see why.

    Anyways I was wondering if the same process is required for other mods using Type C or if it is just mods using the Quest chipset? I also wonder if there will be a specific version of AF or RP for Type C mods since that seems to be the standard everyone is moving towards. And like someone said, it's becoming harder to find PCs with USB 2.0 anymore.

    I came here because I have a Lost Vape BTB which is running the same Quest chipset. Is there a comprehensive list of all mods running on it and which will need to follow the advice found on this thread? I assume it should be the same, but am unsure.

    There are still PCIe cards with USB 2.0 ports (starts~$15) and mini PCIe to USB 2.0 (starts~$2) and they are listed at Aliexpress, Amazon and in several online PC hardware stores ;)
