E85 requirements?
Found a gas station with E85 close to my house. Was wondering if I can straight out pump E85 in my tank and mix it with 93? Does the car have to be specifically tuned for it?
What is your set up so i can tell you how much injectors and fuel pump you will need.
You will need the lines, filter and regulator they must be ethanol compatible.
And you should get an EMS.

-255lph walbaro fuel pump
-680cc injectors
-Aeromotive Fuel pressure regulator
-blitz access ECU
-Emanage (Blue)
Have more stuff but that should cover all the fuel.

I would not go directly on it for a long time because the ethanol will break down the filters you have currently.
You will need new filter, better injectors, new tune.
to do it right you should have teflon lined fuel lines and never have issues with it.

Good to know! I'm probably not going to run E85 anytime soon. Just wanted to know the options and procedures just to run e85 since i just came along a pump.

ProEfi is the only one that can do so far and i have been looking into that Option and it's just no way i will $5k on ECU installed and tuned.
With AEM you will need a laptop to switch your tune.
AEM V2 will have the flex fuel capability in couple months.

I know in the aem you can have 2 boost settings, so you could manually switch between low boost (for pump) and high boost (for pump +meth injection). what they do is tune for the pump gas all the way up to the low boost setting, and have the high boost setting tuned for pump + meth, so when you run out of spray you just flip to low boost.
There are even secondary fuel and timing maps under the nitrous option that can be used for running full E85 at the flip of a switch.
The problem with E85 is if you were running a mix of pump and E85, it would require a completely different fuel map in both vac and boost from running full pump or full E85. so I think the simple switching via that method will not work for a Mix (it works if you just want to switch from full pump to full E85). maybe if you had a sensor that sensed the percentage of E85, you could do an all across the board fuel and timing change under the user defined variables, but i doubt it will be an all across the board change sort of thing.
