r/FireBoard

Hello all, I'm having some issues with my fireboard 2 drive on my masterbuilt 560 gravity series. As you can see on my graphs, it doesn't hold temp well. Does anyone have any luck with certain settings? I've had to run my max fan speed way down as it shot past my initial set point and wasn't coming down. It is running off the built in battery. The fan just seems to either run at the max fan setting or off rather than modulate.
