Because of the way ethanol burns you will see huge reductions in the HC and CO emissions. The blend you are running should burn more completly (because of the ethanol mixture) which greatly reduces the amount of CO and ethanol doesn't release any HC when burned like gasoline does.
The mixture you are running you could probably go to the smog place catless and pass with flying colors.
