Any other QHY367 Users? need help

So I got my hands on this camera a few years ago but finding information on it has been impossible and emails to QHY have gone unanswered. I've seen one old post on CN that says unity gain is around 2800 but that's all I've been able to find, so I'm not sure if that's accurate, it does produce usable results albeit they are noticeably more noisy than my uncooled Nikon D850 images are. I'm also not sure what would be considered a standard low or high gain setting for it would be like how ZWO has those settings preset for its cameras in its software. I also don't have a clue as to how I'd go about experimenting on finding those settings and even if I did I don't have the time, I work over 120 hours a week and on top of it due to being in the subtropics I've only had 4 clear nights in the past year to image and 3 of those were spent fighting a mount gremlins. If anyone could give me some pointers on using this camera I'd greatly appreciate it.
