I'm still learning about leaning. So one of my questions were what happens if all the clyinders are not at the same tempature. Do you lean on ROP to the hotest cylinder and use it's EGT to set the whole engine. And then what do you use on the LOP side do you still use the hotest cylinder? So if your engine has a spead of CHT's what do you use because if you use the wrong CHT then you could have the other cylinder running in the red zone I think.
Reading your EGTs, on the rich side you lean based on the cylinder that peaks first whereas on the lean side, you use as reference the cylinder that peaks last.
