Unique Calibration
The Emissions/Corporate Average Fuel Economy/CO2 Compliance Department is responsible for assigning these calibration numbers. Unique calibration identifications are assigned to cover similar vehicles to differentiate tires, drive configurations, final drive ratios and other certification-significant factors.
These 2 characters are selected by the analyst to identify information unique to each calibration. For example, using the number 2 to denote a 2-valve engine versus using the number 4 to denote a 4-valve engine offers an easily identifiable difference.
