Pork Shoulder on for overnight cook. A question

Options
Have a shoulder on and am planning on cooking it until mid morning tomorrow. Using Digi-Q. Have got target set at 255 and have achieved that temp. Question is - plans are for it to get cold tonight (around freezing I think). Should I go out and try to close down the vent a little at the top for heat conservation providing I don't get in a situation where fan has to keep running to compensate for smaller exhaust opening? Trying to make sure coals make it all night.

    By the way. 8.2 lb bone-in shoulder. Rubbed with mustard then texasbbqrub.com Grand Champion (Thanks to Cazzy). Cooking with cast iron plate setter - feet up then stainless grid. Cut and scored fat cap prior to rub.

    Just crack the top vent. The guru is supposed to keep the fan moving to force the air. I have seen where folks have set them to where the fan was not running much and it melted the fan.

    @Hibby - I wouldn't worry too much about the cold, it's 32 degrees here in Chicago with 50+mph winds and I'm getting ready to throw 12lbs of shoulder on for the night.  No Digi-Q, but it seems to always work if I get the lump right.

    I have a little leakage on my gasket. I almost close my daisy wheel all the way. You might also check your blower damper....I go about 50%.

    No ...I have a little leakage on my gasket jokes.

    Presently have damper at what appears to be 50% and settled in Rock solid at 255. Smells good. I need to make some good Q. Have way too much invested in this stuff to not use it.

    Actually, I think your logic is backwards.  If it gets real cold, then you need more fire to keep it warm, that means more airflow, not less.  However, I suggest as others do, leave it the same and let your Digi-Q do it's job.  Fact, the ceramic egg is an awesome insulator, you have nothing to worry about as long as you put enough fuel in at the beginning of the cook.

    I must have not put enough fuel in. Woke up to pee at 0715 and when I hit the top of the stairs, I could hear a loud beeping. Turned out was the Digi-Q alarming that the pit temp was low. I went on porch and found it at 155 (as opposed to 255). Didn't take the time to see if fuel was left but I doubt it as the fan was running. Went ahead and did FTC and will double-check the internal temp here in an hour or so. I might pull early and hold in oven until lunch.

    Hmmm, interested to see how you like it on pork.  I've only used GC on brisket.  

    With the sugar content, i'm sure it will be great...

    Holy mackerel - this pork is goooood. Pulled great - still very juicy. Great bark! Poured a little Franklin sauce on it and delicious. Couldn't be happier.
