In patents by manufacturers which sited that patent, they seemed to focus on cold starts, but not continuously trying to vaporize fuel. Which lead to me finding so information on Delphi heated injectors, focused on improving cold starts when using ethanol. The injectors were heated for 4seconds before cranking, and then left on for 86seconds
In Figure 15 we can see that although focus was not fuel consumption improvements, the total obtained reduction was 0.4% during FTP75 emissions cycle. When heating was activated the burned fuel decreased from 43g to 36g and fuel at exhaust (unburned) decreased from 7g to 2g.

Woohoo 0.4%! Take that unicorn corral!
