DI NA engine on e85..commanded Lambda?

[benf]

I see a lot of tables for non DI engines for target AFR(lambda) settings but don't see any for a NA DI v6 with stock internals, just bolt ons. Anybody out there found a sweet spot range to target? I was running good on 93 octane with a .87-.89 range Lambda. I have a flex sensor installed. Spark has been adjusted for the most part.

I see that you are looking for other to post up. But you will want the commanded lambda to be same for ethanol fuels and non ethanol fuels. If you found that .87-.89 lambda worked good for 93 octane(10% ethanol) fuel, then I would target that same lambda for all other ethanol percentages as well.
