> 30-35% decrease is about what you should be getting if you do nothing but scale your VE. The O2 sensors will force proper mixture in closed loop. Lambda is lambda as far as the sensor is concerned. 9.765 for E85 = 14.7 for gasoline = 14.13 for E10 = lambda 1.0

i’ve been running e85 for about a month now, i love it :wow
