Bear, here are my findings:
-ambient temp of 63F with 71% RH
-set smoker to 215F
-when my Maverick hit 215F, I turned off the smoker (the MES display said it was at 195F, thats a huge diffs..... explains a lot of the over swing in the beginning, as it vastly overheats)
-the temps on my Mav topped out at 235F
-quickly turned on my smoker again and set it to 225F, smoker temp said 205F
-smoker continued to them heat until 225F, and my Mav said the temps were 255F at this point
-heat then coasted until smoker temp was 236F and Mav said 264F (a big diffs)
-I then opened the door to put the BCBs in, smoker temp dropped to 220F with Mav saying 212F
-it took 2 minuted for my Mav temps to hit 225 from 212F (not bad at all)
-Smoker temp was back to 225F 6 minutes later, then Mav temp said 250F
Im currently watching the temps and I must say, it probably takes a good 1h for the temps to stabilize. The MES cooks at WAAAAYYYY too high temps in the beginning of your smoke. Preheating and babying the temps seems like a prerequisite before putting in your meat.
1 hour later = Mav temp topping out at 253F and bottoming out at 212F with the smoker temp set to 225F. Still cooking on the high side.
Bear whats the best way to stop the MES from cooking your meat at too high temps for the first 1.5 hours? Maybe set the smoker to 215F for the first hour? Then bump it up to 225F? The other day I set my smoker to 225F, put in my AMPS, turned it on, and went to the store. I can only imagine my ribs cooking at 300F for first 30 minutes..... What the heck!
