does the ECU need access to a wideband O2 sensor for the car to function better... or is it used in conjunction, in tuning the car with stock o2 sensors. I've bought a wideband sensor and gauge... I know it can be logged but is it possible or beneficial to have it tied into the ECU?

I couldn't find any threads on this topic if you could link me would be great

Thank you for any response
