    Well, I filled up the car with E85 tonight. Still had just under 3/4 tank of gas so only took 5 gal of E85. Took about 2-3 miles to get up to 27% E85 but took another 3-4 miles for the AFR to drop down to 13.12. So looks like I need B0187 added into my OS so I can adjust it to make the change a little quicker. LTFT are still a bit on the fat side at -10 to -15, so might bump the IFR table up a little to bring them down. Car seemed to run just fine though

    Leaving to drive from Texas to WY tomorrow, so we'll see how the MPG is at least on this first tank. E85 was .79 a gallon cheaper then 93oct.

    So any chance of getting B0187 added for my OS? Been running E85 for a couple weeks now when I'm close to the pump, but takes a while for it to change over in the tune once it sees it. So other then that, seems to be running good!

    I just finished up wiring this in on my 11 eco. When I enable the sensor, it's showing 100% alcohol when I log. I've double checked that everything is wired properly. Something I noticed that I thought was a bit weird though, is that I'm seeing +5V on the Out pin on the ECM side. Is Pin 34 always going to be the one for the Alcohol out sensor line? Any advice or things to check would be appreciated.

    I just threw my multimeter on the alcohol sensor output line after disconnecting it and I'm seeing about 8 mVAC at 57-60 Hz so it seems like the sensor is working.

    Sorry to say, but the upgrade doesn't seem to work on the 2011 Cruze, exactly the same issue you have run in to, the ECM doesn't seem to read the sensor correctly.

    So, what's the possibility of swapping in an ECM from a '12 Eco into my vehicle then?

    I don't know how well that would work, other modules might not like it, but they are pretty cheap used, might be worth a shot.

    Where can I find the actual terminals for the x3 connector?

    I've gone the opposite route on our 2011 Cruze. Rather than add a sensor, I just activated the flex fuel algorithm and filled out the tables. There were around 15 I had to fill out. Will be testing over the next few days. Thanks for all the great info and what y'all do!

    So is it safe to say 2012 and up cruzes are able to be fitted with the sensor and tuned just not the 11
