Earlier this summer I purchased a new Louisiana Grills CS 570. This is not my first pellet grill, but it is my first pellet grill with a PID controller. The first 6 or 8 cooks I hated it. I would start the grill, set the temp to 225, and within 20 minutes the temp would sore to 285 and then take forever to come back down to anywhere near the set temp. Over an hour. Now after 15 or 20 cooks I start the grill, set the temp to 225, And the grill temperature slowly rises to about 235 and settles there. This takes about 30 minutes. Great! OK, now for my question. I have read that a PID controller's performance will improve after several cooks. Is that true or did I just have a bad dream or something?
