An aircraft engine system includes a main engine having a main engine speed; a starter coupled to the main engine and configured to drive the main engine with compressed air; and an auxiliary power unit (APU) system coupled to the starter and configured to provide the compressed air to the starter. The APU system includes an APU with a compressor to generate the compressed air, and an APU electronic control unit (ECU) coupled to the APU, the APU ECU configured to receive the engine speed of the main engine and to control operation of the APU to modify an amount of the compressed air to the starter based on the main engine speed.
