An engine monitor includes a first tuned modeling unit, a second tuned modeling unit and a monitoring unit. The first tuned modeling unit models dynamics of a first engine by processing first control data with a first engine model to provide modeled first engine parameter data, and at least partially adjusts the modeled first engine parameter data for model error in the first engine model to provide first tuned parameter data. The second tuned modeling unit models dynamics of a second engine by processing second control data with a second engine model to provide modeled second engine parameter data, and at least partially adjusts the modeled second engine parameter data for model error in the second engine model to provide second tuned parameter data. The monitoring unit correlates the first and the second tuned parameter data to monitor operation of the first and the second engines.
