I'm not sure, what you need.. another Time Line for 800s max? To edit timeline you will need to replace 660s to 800s in the dx equation: dx = 275 / 800 / 2 = 0,171875 and also edit the nextion hmi file by replacing the background 0.png to new one with 800s time line values.

regarding to config pid values, it's not easy, depends from few things, start from P value 50 or simply go to wiki page https://en.wikipedia.org/wiki/Proportional–integral–derivative_controller check manual tuning
