The Fuel Barometric Pressure Correction Table is used to correct engine fueling based upon atmospheric barometric pressure. The number in each cell of the above table represents a percentage change in fuel output for a given represented barometric pressure value.

An example of where Barometric Correction would be used.

On a vehicle where TPS is used for load measurement. Barometric Correction is used as a means of correcting fuel delivery as atmospheric pressure increases or decreases based due to changes in weather conditions or altitude change.
