    Any E85 users?

    Looking for feed back on people using E85. Mainly if there are issues with anything on the fuel system that it is not prepared to run alcohol and gas mileage. I understand the great performance increase it gives you. As it is equal to 105oct and no carbon build up. Plus it is forgiving on the air/fuel ratio you run vs if it was gas.

    Also I live in Wisconsin so I, like many other states, get 3 blends of this thru out the year. E70(winter), E74(fall/spring), E79(summer). Wondering what tune it comes with when you order it because knowing this will greatly effect the a/f ratio. Plus I assume its mandatory to run a wideband?

    Thanks in advance for your input.

    This is tuned for it or you just add it and you are having the computer to make up the difference?

    I'm probably buying the kit this weekend.

    ICruze2, hows this tune? Is it different than the standard Trifecta tune?

    A lot more Sonics have bought the E85 stuff than Cruze guys, and they all love it. One guy went from running mid 15s on his 93 tune to running low low 15s on E85, but with a worse 60ft time. I'd say he'd be easily in the 14s if he could get his 60ft down with the added power. 93 tune he was running like a 2.0-2.1 60ft and I think his best on E85 was 2.4

    Are there any E85 vs. 93 charts you can show Jerry?

    Is the 190hp/220tq numbers at the wheels or crank? Just curious, in case I should keep an eye on the clutch in case I get a little carried away with this tune in the empty mall parking lot covered in a blanket of snow.

    Also, I wonder. If E85 burns hotter than gasoline, I wonder if this will help the warm-up times of the Cruze to get warm air for those frigid mornings!

    I try to tell people how magical this stuff is when I tune/mod there 3800 and I can say its 25-35hp over your best dyno on 93. This application I could see 15-20hp over the 93 tune. But like I asked what about adjusting for E70,E74,E79 every season change?

    E85 burns cooler which is why you can run more boost/timing and a lot less prone to detonation (KR). I usually recommend to others not running it in the winter because of the longer hard starts.
    With the 93oct tune I'll see the car maybe just leave the bottom of the temp gauge after a complete 20min warm up on remote start. (I know you hyper milers are hating me for that statement lol)

    I will be getting e85 at some point in the near future. I won't install until a little later I plan on getting the fuel sensor to have the auto-adjusting ECU.

    To answer your question in the OP, the Cruze fuel system is completely fine on e85. You just need the tune and injectors to run it.
