I think I found settings that worked well for me.
P=12, I=.004, D=6
Fan output Voltage on above 0% min 10% max 60% startup max 15%
It held at 225 + or - 3 to 4 degrees for a few hours

I have an older Big Steel Keg (before Broil King bought them)
I am also using this Damper (https://www.thingiverse.com/thing:1177115)
I am having bad problems with overshooting of temperature. I was wondering if anyone else has this setup and what their PID, Fan and servo settings are?
