Just setup my retune date with Evans to get an E85 map. Since I already have 1000cc injectors I don't need to change them since I'm not looking to get over 450hp. (i run that now, want the E85 for better reliability)

Also I can change my maps on the fly even w/ a mix of 93 and E85, he will st the o2 feedback with a greater range of adjustment to keep the a/f mixture consistant. I have a 3 yr old Samsung UMPC that I can keep in my car to swap maps if and when I need it.

I expect to mostly run E85 however since I have several stations in my area, with one less then 10miles away.

 

Explainn how it is more reliable

 

FYI this is with a turbo application not NA. I don't have a complete understanding, but my tuner highly recommended higher octaine for cooler temps and better timing.

 

NP, I just dont see E85 being more reliable, for the first reason how about manufacturing control of the fuel itself. Never mind what it does to your fuel system. E85 is bad news!

 

so , did you redo your fuel system to work with E85 ?

It eats Aluminum and rubber , It is also conductive unlike Gas . I think they make a additive you can mix to prevent that though as you pump is submerge in gas .

Just a few thoughts .

 

there is another (as always) thread going on in FI about E85. People are saying it takes a very long time to eat through the fuel system. I do want to get more clarification on this. My build since day 1 has been all about reliability and doing everything the right way. When you say conductive, it's news to me that gas isn't conductive? Or are you saying E85 is more conductive than normal gas? I do keep a fire extinguisher in my car, but if this is something to be worried about I will certainly consider that seriously.

I can make a ton of assumptions on what you mean by manufacturing control, but I want to do my best not to assume what you mean. That said, if you are talking about driver control, I've manufactured so much of that, it sometime seems pointless to have the type of setup i do. I usually drive 60-70 on the highway, every now and then when I feel comfortable I may do a wot pull in 3rd gear but I never (well maybe just a couple times )continue into 4th. The biggest benefit I find is being able to drive in 3rd and 4th and not having to always shift into 2nd to be able to get nice power out of turns during normal back road driving. Don't get me wrong I love that our car well ap1's rev to 9k, but I don't want to use that entire engine speed band in normal somewhat spirited driving.

Like I said in the beginning of this post, my entire build has been about doing things the right way and for reliability. The fact is, my tuner who is one of the most respected tuners in the country, suggested that running a high octane gas would create a much better environment for my engine. I don't want to spend $8 a gallon on 100 octane, and I have E85 nearby. Plus I can somewhat pretend to feel like I'm being more environmentally responsible.

I will be able to switch back and forth with relative ease so I alway have the option of sticking with normal gas and running E85 if I'm going to the track or during the hotter months in the year.
