What you will need is an analyzer that measures ethanol content and a way to send a signal (0-5V) to the ecu.
This signal neds to be calibrated and properly tuned to provide additional fuel to achieve the correct ratio. Ethanol requires around 30% more fuel to achieve the proper afr.

Keep in mind you will run out of injctors (or fuel pump) sooner when you are on corn juice.
