Has anyone here re mapped their 2.4L computer to run E85? I have heard good things about running E85 in performance cars, burns cooler than gasoline, has a higher octane rating (about 105) etc. opinions?

 

you need to run alot more injector to do it right but i havnt heard anything bad. why not be the first one to do it

 

I want to try and figure out how do it. I know a guy here who re-mapped his mustang race car. This may be something I may be the guinea pig over.

 

If I remember correctly, unless your motor was designed for E85, you will corrode certain parts.

 

Hmm Id hope not lol. I will talk to em' and see what he has to say. By no means do I want to ruin my motor lol

 

hmm i know an ecotec race car that might be running it sometime all that needs to be changed was the injector size

 

Unless you are runinng high compression or a turbo/supercharger you will not see much benefit from e85.

 

yeah, i read this too. you have to replace the gas tank and fuel line with a material that sustains the ethenol.

imo e85 is not a worthy sustainable alternative fuel, but i'm sure it would make a fine race fuel.

 

The fuel system is already safe for alcohol from what I understand.

It would be easy to tune for it. I would if it was available here.

 

You heard wrong.
It has less energy per volume, therefore you will actually be losing power.
And yes... it will actually over time corrode unprotected aluminum parts within your engine.

 

WOW! Yeah E85 can be corrosive to unprotected/uncoated aluminum! Didn't know that.
Guess our heads wouldn't like that much.

 

yup...
Really I shouldn't make such a big deal of it... cause anyone running meth injection is doing the same thing (methanol is also corrosive).
The only difference is that with meth injection your only pumping in about 10% as much, cause it's not the primary fuel, and isn't always being sprayed.

 

You'll wear valve guides and seals before you'll wear alluminum in the head from ethanol.

Between the price and the octane you can't beat it for a performance car. After I get the TVS installed in the next few days, I'm going to see how much overhead I have left with the injectors and fuel pumps and end up running e85 hopefully on my LSJ.

 

Under pressure (boost) the corrosive properties are multiplied.
On a 6.6 Duramax that we (SRC) converted to dual fuel ethanol / diesel, we had the intake plenum corrode though in about 14 months..... nasty stuff.

 

Thats true, it will wear much more under boost but I have been following maggie equipped LS1/2s that have been converted and they so far have shown no signs of abnormal wear and tear outside of the ordinary.

I would do it right this second but I have to watch and see what this new blower is going to do to my stock and supplemental fuel pump and 79lb/hr injectors first.
