Fuel/air mixture adjustment on fuel injection

I am familiar with fuel/air mixture on a carb. engine, not fuel injection. How is the fuel/air mixture adjusted in fuel injection engines? 91 4.0 Wrangler

Automatically with input from sensors I believe.

You can't adjust them, everything works based on the input from sensors and factory mapping, you would need a standalone engine management system or a piggyback computer to adjust the fuel mixture or the timing...
