Im installing a mase kit in my s2k. I noticed that there are 2 O2 sensors, one goes on the down pipe… and the other goes on the Catalyzer. I was told by a friend that once I install the turbo, i would cancel them both (stock O2 sensors) and only use one that is actually my air and fuel gauge. How do I cancel them? just cut the sensor off? Is that really what I should be doing?


Thanks in advance

You can leave the secondary o2 sensor in place if your EMS will allow you to disengage it through the ECU.


However, the best bet is to remove it and wrap the connector if your EMS will not allow you to do this.

If your running an aem ems like me then your friend is correct. The ems will not read or use the two stock o2 sensors. It will just read the aftermarket wideband o2 sensor for close loop operation. I removed me stock o2 sensors and just plugged the hole with a bolt.
