iv got a prosport wideband o2 kit, but this is to be used in addition to a stock o2 sensor...now i was thinking the other day

the stock o2 sensor simply sends a signal to the ecu..which is narrowband, correct?

is there any reason i couldnt take a wideband reading from my new bosch sensor and use that to send to the ecu...as its still going to be reading the mixture isnt it? so in other words...replace my standard one...and use my new one for both jobs?

i cant see why not

It doenst work that way.
A narrowband works with a voltage between 0 and 1 volt, for lean to rich.
A wideband uses 0 to 5 volt.

So 1 volt from the original sensor is way rich, 1 volt on a wideband is a very lean mixture.

There could be a solution to your problem.
Most Widebands come in a kit, with the sensor, a gauge and a controller.
Lots of them have the function to emulate a narrowband signal.

So then you could remove the stock sensor, and use the emulation to supply the ECU with a NB signal.

i dont have a controller, its just a gauge kit to monitor the mix nevermind!
