A method of controlling a motor vehicle is disclosed. The method can be used to determine an ambient pressure value without the use of an ambient pressure sensor. The ambient pressure value can be used for controlling a set of fuel injectors. The method can include provisions for adjusting the ambient pressure value to correct for errors introduced by engine wear and other factors.

Method of determining ambient pressure for fuel injection

A method of controlling a fuel injector is disclosed. Multiple airflow rate regimes are associated with different fuel injection control methods. In one example, a low airflow rate regime is associated with a speed density control method and a high airflow rate regime is associated with an airflow meter control method.
