When the engine load and speed has reached a certain limit, the correction factor will gradually increase as the load or engine speed increases further. At the same time, the closed loop will be de-activated (if it was active) as it would otherwise counter-compensate. This is to ensure that all the air is consumed during combustion and to keep the combustion temperature under control. The result is increased engine torque and decreased thermal load.
