Logging on my stock 2010 Camaro and saw a field called Fuel Trim Cell. It varies in value from 1 to 8 to 15 and other numbers depending on load. What are these and how are they used??

It is which fuel trim cell it is using. Starting from #1 and going up. Fuel trims are used by the car to adjust the fueling in closed loop.
Is the #1 cell the upper left cell? And the #2 cell is the one to the right of it?Originally Posted by Unreal

Here is a table I found a long time ago, it may still be accurate.

The fuel trims is the response to the O2 sensors report of the engin being too rich or too lean .
