There are a couple of forums that are ripe with E85 tuning info.  Give me a sec and I'll dig them up.

You most probably run to lean if you don't have winter blend which is more like E70. With summer blend you need ~40% more fuel for the same lambda. Why it is 40% I have laid out more detailed on audizine
