I'm running an OC Pecos smoker with oak and an inkbird 4 probe testing the heat differences in 3 different places if the cooking chamber. 1st probe is farthest to the left by the chimney at grate height. 2nd probe is dead center of the CC at grate height and the 3rd probe is far right closest to the firebox at grate height. About 2 inches away from the water pan with water in it. Included is pictures of above my tuning plates(I hope you can see it well enough) and the other photo is of probe 1-3 across my cooking chamber. I have 5 tuning plates(4 dirty and 1 clean. Just added it) the first one if you cant tell Is butted up against the heat deflector plate off the FB. And the others are spaced as seen in the photo. I'm curious to know why the middle of the CC is so much hotter than the outsides 1 and 3....does closing the gap of the tuning plates lower the heat in the center(#2)? Or at least bring it closer to leveling out with 1 and 3?....also #3 stays right at or around 232°-235° pretty steady...is this because water pan so close? How can I bump that up closer to the 250 range? Just seeing if anyone else has run across this or if to close the gap cools it off and widening it heats it up and so forth. Any tips or suggestions will help tremendously. I will be happy if 1-2-3 can all be within 15 degrees of each other. Maybe even 20! Thanks guys!
