ECU Tune e85 vs 93/91 Gas Performance ?
For those who have their ECU reflashed, have you noticed a difference in gas mileage? I know e85 burns alot quicker then normal gas. So i imagine mpg must be worst, but are there any actual results?
I know MPG is dependent on the driver, so please include your driving style. |

I get considerably better gas mileage with pump gas (est. 25-26MPG) than with E85 (est. 18-19MPG).
E85 makes the engine run so smooth and offers noticeable power so, for now, I'll be sticking with E85 with a pump gas tank every 6 or 7 tanks. Edit: I drive like a donkey. Because race car.

Interesting experiment, it can be fined tune from described "Agreed. Really what I would trust is your trip meter/odo. Drive a set amount, fill up, calculate mileage based on miles driven divided by gallons filled up; boom gas mileage. " measuring at every 250miles, and filling it to only first click. then calculating the milages. I cant wait to start calculating my stock MPG |

The numbers are just for example. But that is the absolute correct way to do it. I believe brichard for his final numbers did it the proper way.
