Changing Stoich in $0D

Most if not all fuel available to me is going to be E10. Can I change Stoich to 14.1-2:1 in my $0D .Bin?

Yes, 13.13 is the accurate calibration.

Forgive my stupidity, but that makes no sense to me. Where and how do I change that?

Engine Constants folder "Stoichiometric AFR "

All I have in that folder is Injector Flow Rate and Cylinder Volume. Wrong XDF?

Mark means 14.13.

In my experiance this change doesn't seem to make a difference in how the engine runs and I believe it's because of how Lambda works, and with the bin really being set for Lambda but displayed as AFR through the use of formulas, it doesn't change how stoich reacts.

I don't believe it will hurt, just that it doesn't seem to something to stress over.

I've read the thread "AFR Gasoline - E10 Wide Band O2 sensor tuning using Lambda" about 15-20 times and still hurts me brain.

However from other posts Mark mentioned easier BLM tuning, which is where I'm at right now with my first attempt at tuning.

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.
