From what I have read and seen from people using E85 and tuners I have talked to, 880s are the bare minimum for E85 even on a stock Evo, and 1000s are not too big for the same setup, but will cover you for a turbo up to and including a green or 50trim. 1200cc or bigger, like 1600 of you are going with a bigger turbo than that. beyond 1200 supposedly becomes more of a challenge on the stock ECU in terms of idle and cruise.

 

We got 1200cc's to work on E-70 and for pump fuel.

Was a little tricky but I got it to work.

I'm running E85 on a daily basis on 660cc injectors... I'm too poor to afford bigger ones :P

 

just out of curiosity, would you happen to know what duty cycles you are seeing on the 660s?

 

how about the avc-r?? if you were on a road trip and couldnt find e85 could you just turn the boost down using the ebc and use premium??

You'd still be pushing way too much fuel because of how much more you need when running E85 (30%).

I know one thing I'm going to be doing is get two maps. I have the Cobb AP, so I can just get pro tunned for both E85 and premium, and just reflash to what my situation on fuel is.

 

Don't forget about E85 switching down to E70 in the winter and back in the spring!
Eventually you'll want 3 maps.

 

Yeah. I'll need all summer just to be able to payoff my bills and then afford the E70 map.

Tuning is not cheap.

 

no but oh so worth it

 

Not trying to suck up or anything, but FWIW Mitch gave me what I thought was a very reasonable and low quote for 3 different maps...

 

at 26psi on stock turbo, duty cycle is at 92%. So i turned the boost down to 24psi

 

what kind of mods do we need to run e-85 on evo8? need help this is my first time having a turbo car so i want to keep it simple like simple bolt-on

 

Anyone know if in AZ they switch to E70 during the winter? I'm about to get another evo and want to run E85 daily since theres about 6 pumps here with it.

 

I dont think that they do. I think since the weather is warmer they just stick to E-85.

Also depends on the gas station I would imagine as well.

To find out for sure...call the gas station and get the number of the distributer.
