E85 and cooled EGR

Consider this study was done on port injection but I bet the effects would be further enhanced with DI.

"Full and part load eFFV engine performance has been
significantly improved by adding cooled EGR to the
architecture. Performance was improved by increasing
compression ratio, eliminating the need for fuel
enrichment, and improved combustion phasing.
Performance improvements were identified at 2800 and
4000rpm on fuels ranging from E85 to regular gasoline.
Addition of 3% H2 significantly increased burn rates and
stabilized dilute combustion whereby enabling higher
specific outputs and improved fuel consumption. Full
load BSFC was improved by 20-21% compared to the
baseline for premium gasoline, and 8-10% with regular
gasoline. Full load BTE improved by 9-10 percentage
points with E85, E50, and premium gasoline. Full load
fuel consumption was only 9% higher with E85
compared to the baseline engine even though there was
25% difference in the energy content of the fuel. EGR
can be used to allow engine architecture to be tuned to
the benefits of E85 while maintaining performance,
emissions, and fuel economy with gasoline"
