How to tune for e85?
 

Hey guys Im trying to tune my miata for e85... its so cheap and seems to have a lot of pros. Now will I need to worry about the e85 corroding the shit out of my system since its a 96?

My main mods:
big 16g turbo
head studs
wally 255
aem fic6 (good tune for pump gas)
all forged internals
1000cc injectors
aem widebande

I have the capacity to flow any amount of needed fuel I just want to make sure the fuel can handle the extra corrosive properties of the ethanol.

Now, if my system will be able to handle it what should I expect my cruising, idle, and boost afr's to be?

I have heard that a good way to start the map is to add 30% onto the map and go from there.

after some in-depth research it seems that I should shoot for 11.5 @ WOT 13-14 for idle but what about part throttle cruise?

Run as much ignition advance as possible, all the time. The whole map. All the way up.

1. Ditch AEM FIC

2. Install MS2 or MS3

3. ???

4. Run E85

5. Enjoy life more

ok, so with the fic unit still in and my wideband set to gasoline what afrs should i be shooting for.
