I have a Gen 2 EX4 that I got just before Thanksgiving. It's running software version 1.4.2783 and controller version 0402. I've also removed the pellet ramp and finger guard, and have put a gasket around the three contact sides of the lid. I've not really done a long-ish cook on it until today, so I really haven't had much prior to base my observations on. But I'm about 7 hours. into a pork butt that I've been doing at 275F. I filled the hopper almost completely before I started, so I'm guessing near 20 lbs. of Weber pellets. Based on what I see is left, I doubt that it'll last beyond another 2 hours. Ambient temps have started in the high 40's and have now hit 70, so I'm not fighting against the cold. Seems to me like it's going through fuel at a fast rate. Certainly enough to make we worry about doing an overnight cook; though I certainly wouldn't be doing that at 275. Any thoughts or insights?
