  "textContent": "An engine controller, an engine control method, and memory medium are provided. A second calculation process (P2) calculates an intake air amount without using a detection result of an air flow meter (13). The determination process (P3) determines that intake air pulsation is great if it is confirmed that a difference between an average flow rate (GAVE) and a minimum flow rate (GMIN) is great. The average flow rate (GAVE) is an average value of an intake air flow rate within a period (TO) of the intake air pulsation. The minimum flow rate (GMIN) is a minimum value of the intake air flow rate within the period (TO). When it is determined that the intake air pulsation is great, a calculation method switching process (P4) selects a calculated value (MC2) of the intake air amount that is obtained by the second calculation process (P2).",
