Now that I have the FireBoard2, I have an independent way to monitor actual temperature in the grill
I have pretty much the same results with my pit temperature variancesThanks RemE, this is exactly what is happening. I spent 6 hours yesterday after posting this, running several scenarios.
To hit 225 I have to plug in 205, it takes some time to settle but once it does it holds 225 within a couple degrees. To hit 250 I have to plug in 220/225. Anything 300 and above I plug it what I want and it holds it.
I essentially have a 20 degree or so variance until 300 and then its spot on.
I wanted a constant 165* last weekend for smoking some ribeyes and the lowest it would go is 200*. If I cracked the door open just a little bit it would go down and produce more smoke. Next time I'll play with the stack cap elevation to see it that helps.
