Can anyone let me know if the power FC uses the stock narrowband signal for anything.

Reason I'm asking is to see if it's necassary to have 2 bungs in my downpipe or just 1 for my wideband o2 sensor.

Please advise.

Thanks in advance,
Tim

 

Closed loop fueling if you elect to use it, though its kind of a pain to set up, basically you set the area you want to be closed loop at under a certain percentage, and then set the closed loop cutoff to a value just above that, but you have to make sure ALL your other cells are greater than the percentage. For example, my car is .898 correction in low vacuum low rpm areas and my closed loop cutoff is 1.0. most people shy away from using closed loop at all but so far I haven't had any problems, you just need to make sure your tip in fuel is strong enough and that you don't have closed loop operation at points in the map where it would be ill advised like in boost.

 

I run the stock o2 around town to save gas . The wide band is on all the time .I turn the stock 02 off with the PFC if I know WOT is needed .
