Table 2. EMS Calibration Tables, P0 mode
When connecting to AEM’s Series1 EMS, make sure to verify that the O2 #1 Gain option is set
so the voltage from the O2 #1 Volts parameter matches the voltage input at the EMS from the
O2 sensor. An easy way to do this is to disconnect the UEGO sensor from the UEGO gauge.
When in this state, the UEGO gauge will output 2.35 volts. You can then adjust the O2 #1 Gain
until the O2 #1 Volts display in AEMPro reads 2.35 volts.
