How many gallons of e85 do you mix on your car?

[nyc f82]

Curious to see what people are running.
Year/ model?
ZCP/non-ZCP?
How many gallons of ethanol and what map?



I'll start- 2015 m4
Non zcp
Currently running 3.8 gallons of e85 rest 93 w/ 10% ethanol on map 7

2015

4 gallon E85 + cali 91 octane (E10) - map 2

4 gallons E85 + 5 gallons 100 octane + 91 oct E10 - map 7

if I run 5 gal or more E85 I would get stuttering/drive train malfunction map 7 under boost.

2015 M4 non-ZCP JB4 setup (Fuel Pressure Sensor connected, FOL of 72):

E30 = 4.24 gals true E85 / 11.66 gals of 93 octane (E10). 96 total octane.

2016 M4 ZCP JB4 setup (fuel pressure sensor connected FOL of 80):

E42 = 6.7 gals of true E85 (new source, testing closer to E90) / 9.12 gals of 93 octane (E10). 98 total octane.

2016 M4 ZCP Bootmod3 flash, custom tuned by me:
