I'm getting closer to having my Evo back on the road and can't decide to do just a tune on 93 or a dual map on 93 and E85. E85 is pretty regularly available in my area and where I normally travel for work. I honestly don't know anything about E85 other than you use more of it than gas and you make more power on it. Every time I research it I am left confused from all of the contradicting articles. I don't even know if I have everything needed to run E85 or not. Here is a list of everything I have for my car and that will be don once its back on the road, some of it probably has nothing to do with running E85 but like I said I know nothing about it so please bear with me. Kelford 272 cams, Manley valve springs and retainers, stock evo 9 turbo, Walbro 450 with install kit, FIC 1450's, my block is getting bored 20 over because a piston ring gave out and chipped the piston and chewed up the cylinder wall. I don't know if I need any specific pistons to run E85 or not. I have a lot more stuff for my car but I know it doesn't have anything to do with running E85. But if need be I can provide a full list of parts I have. I am hoping my clutch will hold the power/torque because I really don't have the cash to buy a $2000 clutch at the moment plus The clutch that's in it was just installed only 9,000 miles ago but it's only an Exedy Stage 2 which is rated for 384tq if I remember correctly.

Flex fuel sounds like your solution, why not be able to run both, or a mixture and have your tune automatically adjust.

haha I knew I was forgetting about something to put in that post. I was going to ask about the flex fuel kits and what they actually do, how they work and what they allow you to run

most important Thanks for your Service!!!

I figured there were plenty of threads on this but I'm an internet idiot and have a hell of a time searching. I always come up with nothing but google links to other sites. I assume i'm doing something wrong when searching. I really appreciate your help and thank you for your service

no problem! as far as your Exedy I had mine holding 560WHP/510WTQ so you should be fine.
