Ok, So I have built an HHO generator, but what I am wondering is Do I need to hook up an efie thingy between the computer and the o2 sensor on the car?
Will I not notice any performance unless I use the efie thing, or will I notice more with the efie, and some, but not as much without..?
Also I had heard of one guy wrapping his oxygen sensor in aluminum foil, would this work? I always thought that when the car was running lean it would be running hotter, and this would therefor tell the car it is always running lean and cause it to dump more fuel..
Thanks in advance for any help.
