Stock ECU only reads a 0-1 volt narrowband o2 sensor signal. Widebands make a 0-5 volt signal. Basically your answer is no, stock ecu will not read a wideband. Also generally fuel additives will not kill either a narrow band or a wideband o2 sensor (especially not just one bottle). Its lead that is found in race gas that will kill o2 sensors. Most fuel additives do not contain lead.
