I have a 2008 p38+ that I just upgraded to the newer style circuit board. I use the Stove Temp setting since it works better for my particular set up. I followed the recommended feed rate of 4 but it is very hot with a huge flame. I am now at feed rate 1 and the flame is smaller but it's still hot. Maybe I have a bad board or the potentiometer dials are off. Will play around more tomorrow. Thanks for the tutorial.
