I have a digital A/F meter that shows me the magic 14.7 number. I got it because I wanted to "see" what an EFIE (02 sensor signal modifier) would do. But, when the EFIE is off, the A/F ratio is pretty much bouncing above and below 14.7, so it's not doing much, just like you said.

How does this EFIE work? What does the circuit look like? I once played around with the O2 voltage by just adding 0.2 of a volt to the signal with a 3v battery and a simple $5 voltage divider circuit and it gave me a mile per gallon or more. Did not check the placebo effect. Newer ECU's are harder to fool.
