[Injector basic drive time]
Fuel injection is performed once per cycle for each cylinder.
Basic drive time refers to fuel injection volume (injector drive
time) to achieve theoretical air-fuel ratio for the intake air volume
of 1 cycle of 1 cylinder. Fuel injection volume changes according
to the pressure difference (injected fuel pressure) between
manifold pressure and fuel pressure (constant). So, injected fuel
pressure compensation is made to injector drive time for
theoretical air-fuel ratio to arrive at basic drive time.

Theoretical air-fuel ratio
Intake air volume of each cycle of 1 cylinder is calculated by ECM
based on the airflow sensor signal and crankshaft position
sensor signal. Also, during engine start, the map value
prescribed by the coolant temperature sensor signal is used as
basic drive time.
[Injector drive time compensation]
After calculating the injector basic drive time, the ECM makes
the following compensations to control the optimum fuel injection
volume according to driving conditions.

Content
Heated oxygen sensor feedback compensation
The heated oxygen sensor signal is used for making
the compensation to get air-fuel ratio with best
cleaning efficiency of the 3-way catalytic converter.
This compensation might not be made sometimes
in order to improve drivability, depending on driving
conditions. (Air-fuel ratio compensation is made.)
Air-fuel ratio compensation
Under driving conditions where heated oxygen
sensor feedback compensation is not performed,
compensation is made based on pre-set map values
that vary according to engine speed and intake air
volume.
Engine coolant temperature compensation
Compensation is made according to the engine
coolant temperature. The lower the engine coolant
temperature, the greater the fuel injection volume.
Acceleration/ Deceleration compensation
Compensation is made according to change in
intake air volume. During acceleration, fuel injection
volume is increased. Also, during deceleration, fuel
injection volume is decreased.
