True Flex Fuel Cruze

35495 63
So I converter my Cruze to a TRUE flex fuel car today. I installed the 42lbs/hr Bosch "green giant" injector (stock are 24lbs/hr) along with an actual flex fuel sensor and tuned my ECM with EFILive, so I now have an actual flex fuel Cruze!! :D Can run what ever fuel or mix I want and the ECM will adjust for it.

This is the write up I used on EFILives forum showing how to do this.
Chev/Holden 1.4L Cruze E85 FlexFuel Conversion

Here is the sensor I installed in the fuel line so the ECM know how much ethanol is in the gas. You can see on my V2 where it's reading 7.8% ethanol right now and commanding an AFR of 14.24. Which is right since I run pump 93oct that contains up to 10%.

Time to put some E85 in it and see what it does. I did this so I can run cheap 85/87 gas and mix in a little E85 (105oct) and get the performance of running 93 but with less cost. I think I can still get close to the same mileage with only about a 25-30% mix.

Something nobody mentioned or discussed...was other modifications that the true flex fuel vehicles have beyond just engine management. E85 is significantly more corrosive than the regular gasoline with up to 10%, and even that is corrosive, just less so.

Everything that touches the E85 from the tank to the injectors has to be corrosion proof or it will eventually become a problem.
