wideband question

[sham90]

I am new to the k20 I had a lot of b sereis I just got a integra with a k20a2 swap and i am finishing it up it came with a pnf-a05 ecu with kpro3 and hr swap harness. I allready registered the kpro an got the car to start without a tps or o2 sensors because it didnt come with these to make sure the motor was good . I have done some serching and didn't find the answer i was looking for so, my question is does the pnf ecu need a wideband or does it use narrowband and i have a new innovative lc-1 can i use it as primary or it can be used for dataloging only with it wire into one of the analog inputs. thanks for any help

You can only run closed loop using the factory wideband. Aftermarket widebands cannot be used for this. They can only be used for datalogging.

Ok that answere one part, but can the pnf ecu read the wideband and or do I need a narrowband ? Thanks

It must use the factory wideband to run in closed loop.
