Hello, is there a possibility to connect the AEM UEGO classic wideband with the Bosch LSU4.2 with the Ecumaster Classic? I am asking because i saw that the AEM connector is different from the bosch’s one for the 4.2. Has anyone done this before? Thank you!
Are you referring to the AEM 30-4100 or the 30-4110 gauge controller? The 30-4100 uses a LSU 4.2 sensor and the 30-4110 uses a LSU 4.9 sensor.
In any event, the O2 sensor plugs into the gauge controller and the only wire that connects to the Emu Classic is the white wire coming from the gauge controller into one of the Analog Input terminals. You then need to select “External controller” in the Emu Oxygen Sensor setup.
