Wondering if I can run e85 on my jb4 tuned 335. Could I just run like a 20% e85 and 80% 93 or even a 50/50 mix without any other fuel system mods? The car is pretty much stock other than the DCI's, JB4, and upgraded 335is clutch. Also I would run map 5 correct? Is there anywhere I can read the ethanol content with the jb4 interface? Thanks for the help.

Just add in 30-40% and select map5 the autotuning map. The virtual flex fuel sensor (allowing reading of ethanol content without having to wire in an actual sensor) is under development/testing now and details on that are on n54tech.

Ok cool thank you. My buddy who has had a few 335i's told me that I would need an aftermarket LPFP to run it. Any comment on that?

Under e40 you "should" be ok.

Just yesterday I threw in 5 gallons of e85 and the rest 93. Been doing this for years about once a month when I go up to Maryland. Map 5
