I have a 2013 Cruze Eco 1.4T M6. This car is a daily driver and does not have any performance modifications, nor will it ever get any.
Within a 6 mile radius of where I live, I can go to about 5 different stations to get E85. The cheapest gas station has it at $2.499/gal whereas the cost for 87/89/91 octane are $3.959/$4.159/$4.259 per gallon. Even factoring in the 30% decrease in range, there is a favorable cost per mile by switching to E85. From my quick napkin math, the price where the cost per mile is equal is about $3.569/gal on whatever octane. By filling up a 12.6 gallon tank with 100% E85, that cost is ~$31.50. To completely fill up the tank on 87, the current cost is ~$49.88 with the spread being about $18.38.
After doing some research on using E85 on the 1.4T, it looks like the bare minimum requirements that these engines need are the sensor, pigtail/plug wiring, hose, fuel fittings, and the injectors. The
sensor is ~$80, the
pigtail is ~$8, and the hose and fittings should be about another $30. As for the injectors, almost everyone upgrades to the Bosch 42.5# Green Giants. These injectors look very similar to the injectors commonly used in the 3800 world. The
factory 1.4T injector is rated at 28.2# and the
L67 injector is rated at 34.6#. If I go to the junkyard, I can pick up 4 injectors for ~$7 each. After adding up the costs for the sensor, pigtail/plug wiring, hose, fuel fittings, and the injectors, I am looking at an upfront cost of ~$150. Given the spread of what I am saving at the pump and my upfront cost, any fuel used after the next 8.25 fillups should be saving me money before tuning it.
Can I use the L67 injectors for my daily driver? Will the slight increase in flow be enough to handle E85 on a factory engine given my use?[/QUO

you cant just plug in a flex sensor to a cruze, nor can you just change the injectors tuning would be required for both.
