Just an update on E85..... I love it!
I had to really bump up the cold start fueling. From 60 degrees to 30 degrees (F) I am running 30% more cranking fuel. From 30 degrees down I am running 60% more cranking fuel. Fires right up with the extra fuel. I just kept adding fuel during below freezing starts til my crank times were back to stock. It takes a lot more Ethanol to light off than gas.
I average 12 mpg in 100% stop and go city driving not driving efficiently... at all! On premium I was getting 14 mpg. Before the top swap I was getting up to 18 mpg city if I babied it. I only drive several hundred miles a month in city traffic so I don't know what I could get on the highway. The price of premium vs E85 makes the cost a non-issue for me and I am lucky enough to have several E85 stations several miles from my house.
I had to adjust the DIC to get my mpg readout close.
I had to adjust my decel fuel cutoff and bump up my idle speed a little for my cam. Idles same as stock now.
I ended up installing a Racelogic Traction Control system to help with traction. Great mod!
