    Abstract: Modified calibration strategies for controlling an internal combustion engine and monitoring catalyst performance are disclosed. The modified calibration strategies are implemented using an engine and test cell/catalyst chamber setup wherein the engine is a Euro V 1.2 L turbo gasoline direct injection engine and test cells/catalyst chamber are implemented as substantially free of platinum group metals (PGM) catalysts, herein referred as ZPGM catalysts, and synergized PGM (SPGM) catalysts including a stoichiometric spinel structure within the catalyst configuration. The utilization of an open ECU enables the modified calibration of the engine out targeted AFR. The conventional ECU AFR control strategies are not modified to have the ECU AFR control strategies to continue running normally and only the final engine out targeted AFR values are modified by applying offset AFR values. The modified calibration strategies improve engine operation and catalyst conversion efficiency of the ZPGM and SPGM catalysts including the spinel structures.
