So i just hooked up an air/fuel gauge to the O2 sensor coming right off the headers. Im guessin this wasnt the best place to wire it because it jumps back and forth from lean to rich constantly unless i go WOT then it just shoots into rich and stays there until i let off.
Wheres the best place to wire it? prolly off the ECU?... |

according to my teacher it is supposed to do that because the pcm is constantly trying to keep a stoichiometric air to fuel ratio of 14.7-1. so the pcm use's the o2 sensor's reading to see how much air is in the exhaust system. if there is not a lot then the system is rich and then the pcm narrow's pwm of the fuel injector solenoids so its sprays less fuel which means more air in the exhaust which makes it go lean. so it is always changing to compensate for a 14.7-1 ratio
