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.

I will repost this as a thread in ecomodder so you can see the pictures, but this will get you started for now.
