Configuring Calibration Outputs
The AEM default position is (P0). When set to (P0) (Figure 10A), the gauge displays
AFR values. (P1) is the same as (P0), except the gauge displays lambda values. These
settings (P1 and P0) implement a linear calibration with the most useful voltage range
possible (0-5V). The AFR calibration (P2) is linear and similar to (P1) with a smaller
voltage range (1-2V). The AFR calibration (P3) emulates the Autronic Wideband O2
Sensor calibration (0-1V). The AFR calibration (P4) emulates a non-linear Nernst Cell
calibration (0-1V). Refer to the Table 3 and Figure 9 for specific calibration details.
