AEM Wideband install questions
I’m going NA-T on my 92 SC300 and have a couple questions about configuring the AEM Wideband to replace the narrowband output of the stock o2 sensors. Since the stock sensors are voltage based should I run the 0-5V output of the AEM to the o2 sensor input on the ecu, so it sees a signal and maintains values? I’m going to try to adjust AFR’s with a SAFC.

Thats what i have on my Na-t car 1 sensor going to both banks of the computers ecu and my wideband separate going to my gauge inside

Your AEM output can be set to emulate a narrowband (0-1V) O2 sensor. There is a rotary switch on the back of the gauge that changes what the sensor outputs. It will still display wideband values on the gauge. This should work to make the factory ECU happy.

Most down pipes have a provision for multiple O2 sensors. Any reason for wanting to run just one?

So have you figured out which ECU you will use for your NA-t? If you are planning on running the GTE ECU, you only need one O2, it's pretty much the same with the stand alone's.
My setup, and most other turbo setups use 1 O2 sensor for the ECU and 1 for Wideband.
