The blend of the ethenol (corn alcohol) is normally 10% with gas.
Its been in Mich. for years and still is.
The postings kinda reads that some are thinking of using it in a higher percentage. Feds want 15% ethenol in the future.
The jetting and amount of ethenol with compression must be considered.
The more alcohol, the more needed to burn almost twice that of gas.
The mix at the pumps does not need any jet changes.
Its all in the combination of parts used to build the motor, a 12:1 can be built to run on 93 octane pump gas.

As quoted from the site given:
Keep this in mind when designing an ethanol powered vehicle:

"Even after all the top brains have figured out everything on paper and failed to make it work, they still have access to tons of diagnostic equipment and large chunks of money to find out "why not?" Normally, Detroit doesn’t put things on the market unless most of the bugs have been ironed out. This ironing out process has so far taken over 80 years for the gasoline engine."[10] - Michael H. Brown, 1981.

All looks good on paper, just like desiging of the cars.
What looks good on paper does not work all the time in real life.
89/93 octane gas with ethenol is still a 89/93 octane burn rate.
my $.002 cents worth.
