its not viewable the same as other data items, but you can use a histogram to see the trims, same as you can do for wideband. History tables -> BLM tables. Then replay your log to plot it.

So is there a table that I can review the target AFR settings?

Note just looked back at the Basic tuning guide and it states looking at the histogram and selecting target AFR for some reason that isn't an option in my menu..

I'd suggest using the monitors, but you have a number of tools that you can use to figure out what to change, so you can of course use whichever you prefer.

Do you mean in the history tables? Is there a way to add the target AFR in there? to make it easier to compare? It's currently not listed.

I think he is tuning VE though, so A/F table that is not the table to change to apply corrections.
