I know this is a noob question. I been searching on google and even on this forum and cant seem to find anything. I bought the car on e85. I did find this https://www.evolutionm.net/forums/e8...-e85-pump.html


Mods are evo 9 turbo with a 20g wheel. Gsc s2 cams with valve springs and retainers. Arp head studs. RC injectors. Dont know what size. Walboro fuel pump. and tune. Stock fuel rail. No name 3" downpipe. made 391 hp. Thats all what the previous owner told me.

Im assuming to Take out the injectors, take it to a shop, get them cleaned and flowed tested. Clean out the fuel rail. Get the car to basically empty with the fuel light on and driving 10-15 miles and filling it up with pump gas 93. And get a tune. Do i have to do anything else? with the fuel filter or anything? do i have to completely remove the e85 or can i have a little bit in the tank? Any input will be helpful. I am converting to pump because its just more convenient for me to have 93 pump gas. I want to do eveything right with no issues down the road.

 

I have a dual map tune and I switch back and forth from 91 to E85.

If I want to switch back to 91 from E85 all I do is run the tank to the warning light and then pump in the 91. Switch maps from E85 to 91. It runs fine and I have had no issues doing this.

 

question is. do you have 2 maps?? one on regular fuel. and one on E85?

 

Nope just been on e85 here. Could I just run it to the fuel light and then put pump gas in and just get a street tune without wot and just daily driving it ? and burn the 93 and the next fill up get a dyno tune??

 

Doesn't sound hard at all lol

 

Nope... The cars been on e85. Just one single map
