O2 / Lambda Questions

Recommended Posts

Ok, now that I'm getting the hang of data logging I've got some questions regarding the O2/Lambda readings.


1. Should the readings from let's say Bank 1 Sensor 2 vs. Bank 2 Sensor 2 read nearly the same or perhaps trend in the same direction?


2. If the answer to question 1 is "yes" or "very similar" or "should trend together", what would you say to large variances and different trends between the two?


Here are a couple of logs I took.


First Log (without values)



First Log (with values)



Second Log (without values)



Second Log (with values)



There are plot points on Bank1 reading rich and at the same time Bank2 reading lean. You'll also see some trends where Bank1 is trending rich while Bank2 is trending back and forth rich-lean-rich-lean.


Anxiously awaiting replies.
