Right. I smoke at 230*F. When the Mav hits 220*F and the Mes shows 240*F I set the MES one degree lower (239*F) to shut off the heating element and coast 10-15*F. When the Mav says 230*F, the temp I want to smoke at I reset the MES to the temp it's showing (about 230*F as well.) Then on subsequent cooks I know to set the MES @ 220*F to keep from way over shooting, besides it's only pre heating (the door is going to be opened and the two step process starts over.) Two adjustments and your where you want to be and that's every time you open the damn door. Which means, get it right the first time so you only open the door to foil or babysit it.
Hi Kurt,
I should mention, after we repaired my Gn #1 when the Flag connector had burned out, I figured since I wanted to run it a few hours anyway to make sure it's ready to smoke meat again, I would use my method too.
So knowing that mine usually over-shoots by 15° to 25° when running from Ambient temp to 250°, I decided to try to get to a stable 260° as fast as I could.
So I set the Control to 245° & started it up.
When it hit 245° (after 20 minutes), the heating element shut off, but the heat kept rising, because all of the things in the bottom of the smoker were much hotter than the air in the smoker was.
Once it got to 263°, and then fell to 262°, I knew it had peaked at 263° (18° over-shoot).
So I immediately changed my setting to 260°.
That was it-----No more big swings, just from that one small adjustment.
From that point forward, for the next 3 hours, my MES temp went as low as 254°, and as high as 268°. That's between -6° and +8°. I'm quite happy with that.
And it didn't take hours & a lot of babysitting. It was 1 adjustment at the 20--25 minute mark, and steady as she goes for the next 3 hours.
The big thing was after the 18° over-shoot, I moved it up 15°, which kept it from having a big downward over-shoot, which would cause another big upward over-shoot, etc, etc, etc.
One simple move nipped it in the Bud.

What I was saying about having a briquette or two in the chip tray, that nips the downward over run by a few degrees. Probably because retained heat in the chip tray is deflected away from the sensor with my deflector. The heat is still in the smoker but away from the sensor, allowing a quicker recovery. Hell I don't know. Heat is heat and the lack of it is cold. The MES shuts off when heat goes up and trips the sensor. The heat turns on when the sensor calls for it but it may be hotter on the far side with the deflector with briquettes. I don't really care about the effects on the MES with briquettes. It was a side effect of trying to get a smoke ring. I taste with my eyes first and like a smoke ring just like most like a seared steak. I'm just mentioning I experienced a favorable smoking experience when I used the briquettes even though I failed at getting at smoke ring. Brickguy's son had a similar effect I believe.
