Final update! (12/20/21) - I received my 4th new controller on Friday 12/17/21 and it actually has the new firmware! I can increase my temps by 10degs between 200-300deg (210, 220, 230, ...) then it goes back to 50 deg jumps from 300 on (300, 350, 400...). The new board looked almost identical to the previous 3 I received, so I had little hope that it would work...but plugged it in and viola!Update time again (10/14/21) - I just received my second new controller from PitBoss after waiting ~1.5 months for this one. And, as expected...it's identical to the previous two boards and does not provide 10deg increments.
I'm calling back now and expect the same run-around, ~1-2 months of waiting, to receive another controller that doesn't do what they say it does, etc. Really a great experience...
To recap, this started back in AUG 2021 and took 7 calls to Pitboss and 4 different boards to be shipped to finally fix it. Really hoping that all the new boards going out will have the new firmware, but if not, just be persistent . Hope this thread helps someone else.
