Yes they do. In fact the ecu has two distinctly different sets of fuel tables for base and correction (including fuel temperature) that it blends between based upon the ethanol content of the fuel in the lines. Ethanol is not a straight conversion like you are making it out to be. Ethanol has many different properties than gasoline that are addressed by the modern flex fuel ECU's.

Like I said on the "other" board you could swap in the 720's and for the most part in the summer it should work just fine, but your millage will most likely suck, and if you drive it in the winter good luck getting it started. On the positive note you could probably run that stock turbo right through the hood and not have to worry about the engine dieing from pre-ignition, compressor wheel shrapnel maybe, but not pre-ignition.
