Default 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 **** 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.
