True Flex Fuel Cruze

35492 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.

Simply because of demand. I haven't really seen anyone with a Cruze do it but the sonic guys all want to do it. We don't actually do the work, we just tell people what part number to get and where to run the wire to the ECM.

Badnewsracing.net they have the injectors and if you already have a Trifecta Tune they adjust that to compensate. But he dosn't carry the flex fuel sensor you wont need it, but you can't run anything but E85 unless you tune back to the premium tune.

Thanks h3ll, already have trifecta tuned E85 with injectors set up, but it is a pain in the butt in the cold weather!! Plus I want to see what % of ethanol is in the fuel that I am buying! And not having to change tunes when fueling up would be great!!
Cheers, Buk.

The sensor cost me $74, the pig tail was $15, the hose I made up with push lock connectors was $65 and the injectors where $180.
G'day KBRacing96, just wondering if you had a link to where you bought all the parts needed for this mod??

That pig tail is just for the sensor. You'll still need the pins and some wire to get it to the ECM. I got those from a buddy who makes harnesses.
Thanks again KBRacing96, better order the pins too!
Cheers, Buk.
