I agree with most of what you're saying.......but I really don't believe it takes twice as much alky compared to gas. But yes, I hear you, if you're tuned for gasoline, you will be running lean on alky. (as I noted above, don't go WOT)It truly works but you have to use the right stuff.
2 gallons of Denatured Alchy from Home Depot/Lowes to an empty tank will pass with flying colors. All measurements will be at least half of what they usually are. This is my way of sticking it to the man every year. I mean you will have the inspection guy wondering what the heck as it flashes pass on the screen. I've been doing this for the past 10 years or so with a hollowed out cat. I ran it through last week and it was helerious because the car would barely stay idling, surging back and forth. It will run like crap but will still pass so who cares...
After you put the Alchy in you will need to crank the fuel pressure up all the way to 75-90 or change your injector size in your program to a smaller injector so it will dump more fuel in. It takes twice as much alchy to burn as it does for gas so that is why you will need to fatten it up somewhat.
After it passes just run all the Alchy out and replace with 3 gallons of gas and run that dry also. Alchy is corrosive so I prefer to run it dry a few times before I add a full tank.
Forget anything else. 1 gallon would probably do it but It's fun to watch there faces as it passes.:biggrin:
Where did you read this? This is great news. They suspended my plates on my TTA. Been driving around with plates from 1998 for years now.ILlinois dumped its im240 test as of feb 1 2007. so 1995 and older cars are exempt. unless you failed before dead line. then you have to do an idle test to be exempt. they are only going to be testing obd2 cars 1996 and up.:biggrin:
