It won't change how engine runs. Just how the ECM/PCM starts it's fueling calculation. The only thing that will change is BLM readings from having a proper starting point.

Thats the way I understood it after searching and reading today. And since I haven't adjusted my fuel tables yet I thought I would make the correction to the AFR before I corrected the BLMs.
Again I dont see where to change it, in my Engine Constants all I have is Injector Flow Rate and Cylinder Volume.
Is it something I have to add in?

That's where it is in my $0D which is not stock, I re-organized and made it simpler. Use Tools, Parameter Finder and search for it. "Stoichiometric AFR"

Did the search and found it only under "Open Loop AFR Parameters"?

So why the question?
Like I said I've moved a lot around in mine from stock $0D. But there's only one.

I guess I just assumed it would only apply to open loop and not work in closed loop?

The other way... this is the target for Closed Loop. In Open loop there is a seperate table.
