      Can a wide band O2 sensor be used on the SS or will the ECM only read narrow band Just wondering.
      The ECM/PCM is calibrated to read a narrow-band sensor. An interesting feature of some aftermarket wide-band meters is their ability to emulate a narrow-band signal in addition to their wide-band output. This narrow-band signal can be used for the PCM in such instances, precluding the need to add a second sensor bung to the exhaust; only one sensor is needed in such cases.
