I live in SO Cali and here is what I do to pass. In CA the Mustang fits a Gross Polluter profile and for 3 years I had to smog my car. I did the tune up stuff and oil change. Reduced timing to 6 degrees + or - 2 degrees. Run the tank to well below 1/8 tank and buy a case of 91 percent or higher rubbing alcohol. I pour that in to the tank and then head over to a local smog shop. Leave it running while waiting and it passes each time with flying colors. Even the smog guy says that it is running very clean. I am not sure but i think E85 woudl do the same if it was mostly in the tank when testing.
Good luck. BTW my SD 86 failed due to high HCs. The tech told me that its a misfire either due to ignition or burning oil.
Good luck
