| (! channel_has_args(cfg.channel_mode)

I test that asap. I already try to comment it and it’s work fine :

//if (! arg) {  // first frame only, to allow thermal regulation to work
    uint8_t tl = style_2c ? 150 : turbo_level;
    set_level_and_therm_target(tl);
//}

But I am surprised that the functionality appears in the diagram and that no one remarks that it does not work (3H without Multi channel or 4H with) https://lemmy.world/post/1038159
