BASIC FUEL INJECTION CONTROL
The amount of fuel injected from the fuel injector, or the length
of time the valve remains open, is determined by the E.C.U. The
basic amount of fuel injected is a programmable value mapped
in the E.C.U. ROM memory. In other words, the programmable
value is preset by engine operating conditions determined by
input signals (for engine rpm and air intake) from both the crank
angle sensor and the air flow meter.
