converting over to E85, how different should i tune?

[97-gst]

Mods are up to date in profile, gonna get some E85 and put it in this weekend, just making sure itll be okay with my current setup. E316g, 255 rewired pump, 1050 fics, dsmlink etc... So I should try to get my air/fuel to 9.5 instead of 14.7? wot around 11-12, and i should be able to advance timing quite a bit correct? IS it worth the switch over 93 octane?

There are a few threads on here with all the info your asking as it has been discussed a few times.

Search for "Beginner E85" and "Advanced E85"

As Far as your AFR is concerned... . NO

That is If your using the same wideband as you were with gas it doesn't care what fuel is being read it's going to target lambada 1 as 14.7... . I wouldn't mess with timing if your asking, as you can go well behond MBT with out picking up any Knock... .
