Do you need Emax to lean accurately? Also, I’ve heard you need GAMI injectors to distribute the fuel more precisely between the cylinders, or else, they all peak at different points. Since the power to fuel flow curve is pretty steep at LOP this results in a rough operation. That was my limited understanding; I currently rent at wet rates, so I run ROP for best power. If and when I buy a plane I want to learn to operate it more efficiently.
If I was renting wet, I would fly balls to the wall ROP as well.
You do not necessarily need GAMI injectors to run LOP well. My plane has stock injectors and the GAMI spread is less than 0.3 GPH.
In my humble opinion, you need E-Max (or some other all-cylinder monitor) to safely and reliably run LOP at high power settings. Others may differ. They are entitled to be wrong[;)]
