I've had my BGE for a while now and just got my guru, Digi Q DX. Today is my first cook with it and instead of a dry run, which would have been smarter, I jumped in with a butt cook.
I set it at 235 and it held fine for 45 minutes. On with the meat and still ok. I checked back after 45 minutes and I was up to 260.
I had the damper set at 1/3 closed so I moved it to 1/2 closed (recommended by guru site) It dropped to 200 the fan kicked in and now it is up to 300.
I've fiddled some with the daisy wheel but I don't really think that is the issue.
Anybody know what I'm doing wrong or is this simply the learning process for the controller?
