Percentage of ethanol in gasoline

On some SAAB engines, courtesy of a gadget called eSID2, you can monitor the percentage of ethanol in your fuel tank. This is inferred from the alterations in lambda ratio, gasoline is stoich @ λ=14.7, whule ethanol is stoich @ λ=9.0 .

I wonder is this could be achieved somehow on our Z22SE engines ...
