Can I use the narrowband output on the Innovate LM1 to simulate the stock O2 sensor on my S4 TurboII ecu?

Is there special setting or it only need 0-1V narrowband signal?

I know its not something "usefull" to do and that the best thing I could do is install a new O2 bung and put the wideband sensor in it.
But I want to install it that way cause i got a e6x that I will install this winter and I don't want to use the stock O2 sensor, only the bosch wideband sensor.

 

You should be able to use the narrowband output of the LM-1. That's what it's for! If you're really not sure, just contact Innovate and ask them.
