Having been unable to find if I was about to set myself up for failure I just went for it.
A few details, I have ez 2.0 installed on my 68 Mustang with a 433ci FE cam is about (lost card) 235 @.050,.530 lift 110lsa , 10.6 CR.
Not wanting to drain the tank I decided to remove as much gas as possible the fun way by driving the car. When I put the car together I set the gas gauge to read empty at 4 gals , 22 gal tank. I did a little math and figured if I could run the tank below 4 gals I'd be good with e70ish. So I did.
Pulled up to pump and filled tank with $2.88 per gal e85, 17.4 gals later I jumped into the car and reset the fuel setting on the FAST control to e85. That done I turned the key,and, it started and ran fine. That's it , no bucks, bangs, pops. I just drove away and went on to work,of course I did it on the way to work.
I drove it on the set AFR's so it is rich because of the extra gas,e ratio is not 85% more like 70% but cruising around it seems fine. I also have an Inovate LC 1 afr indicator it is showing 15-16:1 as it is set to read gas, FAST afr reads mid 9's.
Saturday I drove it 100 miles round trip up the road to Buda Tx for the Gear Heads cruise at Cabellas , 70-80mph the whole way it just ran,A/C blasting the whole way , water temp the same 195*f.
One issue,get ready Throttle body and FAST ez haters, at high loads, like maybe accelerating from 80-100mph, I got some "chugging" then backing off it showed lean, which it should when it misses. Hummm... flame out maybe? Reset plug gap from .050! to .035 done , problem gone. Thats it.
I have used less than half a tank at 130 miles so I should be near 12mpg , from my gas 16 , did not note odometer when I filled it because the mix is off anyway, and the mileage sucks when the ez is first learning.
A few more details, I'm using a Tanks Inc intake fuel pump with the supplied intank pump from FAST,return system, 43psi. FAST controlling timing .
