GReat Dave you're making me think I got in over my head.
Kevin, don't let Dave scare you. Some have had issues with Aubers, just like anything else, but I never have (and have 3 of them). Like I said to Glock21 - if you're hitting in the 270s empty,
the smoker is working properly. You could be seeing a problem created by something else, such as temp probe placement or use of a drip pan...not sure how you were set up. Bottom line is that, if the smoker is exceeding 250 empty, it is working properly.
Now, onto the Auber. The beauty of the Auber is that it is a simple way to have
complete control over your smoker. Especially if you bypass the stock controller (which is really easy, btw, and I have instructions posted), you take out the "middle man" and let the Auber drive the bus. You can exceed 250 with ease, and accurately. Personally, I love the Auber, and wouldn't own a smoker without it. I use it on the 1, 2 and 3! I also highly recommend the wall-mount probe; it takes out any variables you get with the drop-in probe...it's foolproof!
