Abstract
An engine controller, an engine control method, and a memory medium are provided. A second calculation process calculates an intake air amount without using a detected value of the intake air flow rate. A guard process sets a difference amount learning value as a learning reflected value when the difference amount learning value is less than or equal to an upper limit guard value and greater than or equal to a lower limit guard value. A calculation method switching process sets a sum of a second intake air amount and the learning reflected value as a calculated value of the intake air amount when it is determined that an intake air pulsation is great.
