UEGO and EMS series 1

Hello I am using a AEM EMS series 1 still in my Talon. I have two AEM UEGO's  ( 30-4100 ) installed in the car. I always forget which type in the O2 wizard is the correct choice for these gauages. Currently I have it set to internal UEGO but the 02 readings seem way off so I suspect this is wrong.

My choices are:

AEM EMS Internal UEGO

AEM external controller

AEM gauge

AEM 30-1313U

Assuming that you don't have

Assuming that you don't have a 13XXU box (U means internal UEGO), you'd probably want to select AEM gauge.  This snippet from the 4100 instructions may also help:

When connecting to AEM’s 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.
