Fuel maps? 2011 to 2013 9c3 ppv 87 vs 91 octane?

Hi ,
I run 90 , 91 non e octane fuel in my vechiels.
So I'll ask do the ecu's in the caprice 6.0 2011 / 2013 carry multiple fuel maps for different types of fuel?
If so how many tanks does it take to reset?
In my chevy 2012 / 14 cruze's it takes 3 tanks and they cover 87 to 94 octane fuel.
Thanks for any input.

These cars will run on E85 through what ever is available at the pump. There is a fuel monitor that adjusts for the type of fuel on the fly. It samples the fuel just before the injector system. The timing advance tables are also adjusted accordingly.
