Full E85 on stock system f80 m3

[batman_m3]

Might be a dumb question to most but for the time being I’m looking to test out e85 OTS map from MHD as I don’t have enough access to e85 to make custom tuning worth it yet. Anyway can I run the OTS e85 map on stock fuel pumps? Or do I need upgraded lpfp to handle it/full advantage? Car is mostly daily driven but when I go out of town for work it can sit for up to a week.

The answer is yes, you can. Should you do it? No!
I blew my motor on full E85 from the stock EU6's. 24k miles, two holes in block. Switch to EU5's and then go for it.

I probably wouldn't try an OTS E85 map myself, and I'd run the Bend filter at minimum before I tried any significant ethanol blend. ficant
