Hey guys, I have a M300 permanently installed in my car... My DP Has 2 02 bungs. The stock sensor will stay and I'd like to use the WB sensor to check my A/F Ratio at all times.

How should I set it up in terms of the Grey and white wire and open loop/closed loop etc.

 

Make a switch so you all you have to do is flip the switch instead of manually reconnecting the correct wires.

 

Werd, Get a three way switch and hook the d14 ECU wire upt o the middle and then the sensors on either and, This way you can toggle back and forth between the two. I have my LC-1 wired up with a 3 way switch so i can toggle between narrow and wide so i guess it should work the same for yours.

 

Ok so why would I want to be on the narrowband setting and why would I want to be on the wideband?

 

i just disabled o2 in turbo edit and run the wideband output to the o2 imput on my ecu, running the wideband all the time anyways.

 

i don't know if you wanna have it in there all the time, the sensor looses accuracy after a while
