Connect ECU to following MTX-L wiring:
Analog Wire 1 (yellow) -- 0v = 7.35 AFR 5v= 22.39 AFR
Analog Wire 2 (brown) -- 1.1v = 14 AFR 0.1v = 15AFR
In the Narrowband section it mentions using Wire 1(yellow), but should I ACTUALLY use Wire 2(brown) since MB uses 0-1v? Any ideas?

Are you using the WB sensor for just a read out or for control?
The brown wire appears to give you a narrow band output which your CIS-E /EZL needs for control.
The yellow wire appears to be a wideband output which can be used for read out or control setup.
I still run a OEM narrow band in my TwinTurbo as it maintains the stock control of the CIS-E/EZL.
A wide band is installed in another bung but was only used to program the fuel maps in the stand alone enrichment controller.
The variable in my control that enriches under boost is the manifold absolute pressure and no O2 sensor input.
Check with the manufacturer to see if you could use both outputs, the brown for stock control and the yellow to your AFR gauge.
