That is direct from the N54 tech and instructions for f series JB4.

7) As a general rule EWG cars are not very E85 friendly. If reliability is a concern no more than 30% E85 should be used and the highest map used should be map 2. Using map 5 or map 7 with E85 mixtures may result in boost running high enough to exceed your fueling capacity triggering various codes and/or JB4 safety map 4 switches. If you are more experienced and able to analyze your own logs you are welcome to play around, but we've instructed technical support NOT to provide assistance or advice to anyone exceeding map 2 when using E85 with the EWG platform. If you run map 5 or 7 on E85, run in to problems, and ask for help, you'll get the company line of "for E85 use no higher than 30% and map

However, PWG up to 40% E85 on map 5 should be ok, right?

From n54tech: Models equipped with the pneumatic wastegate & flex fuel connector may experiment with up to 40% E85 mixtures.

Key word: experiment. Always start low and work your way up, ie..3 gal..good try 4 gal..good..go to 5..there are calculators, but I don't know if I would even try too much over 6 gal.

Yeah thanks, that's where I got the 40% from, but I don't recall it saying anything about map 5. I know it says you may be only able to use map 2 possibly map 7. I was wondering why no mention of 5...unless I missed it.

The part about not using anything higher than map 2 is in reference to ewg cars.
