ELECTRONIC FUEL INJECTION BASICS
Electronic fuel injection metering, when properly designed and programmed, is today's accurate way to introduce fuel to an internal combustion engine. With it's many sensors and input signals it can be tuned to meet the demands of an engine operating over an extremely broad range of conditions. The most commonly sensed inputs are:
1) Engine rpm
2) Throttle position
3) Barometric pressure or manifold absolute pressure (M.A.P.)
4) Air temperature
5) Water and/or oil temperature, and sometimes fuel temperature
6) Rate of throttle opening
