your ECU is adjusting the fuel based on readings taken from the O2 sensor - this is why piggy-back AFCs don't work on a Honda - here is part of another thread on this subject:

2: The ECU "auto adjusts" itself.
Let’s say you want to tune in 10% more fuel with your AFC. Fine, tell your AFC to add 10% more fuel. No problem right?? Wrong. What happens to the O2 sensor when it's got 10% more fuel?? It tells the ECU that it's running 10% rich. So, the ECU "auto adjusts", and takes 10% out of the mixture. You've added 10% with the AFC, and the ECU has taken 10% back out to get back to stoich. What's the net increase in fuel?? That's right, 0%. NOW...... Lets add fuel with the AFC until the ECU can NO LONGER adjust (or, you've added so much additional fuel that the ECU doesn't know what's happening, and can't compensate that far). Simple. You run rich. "Hi, I'm the check engine light again. There must be something wrong with my O2 sensor because I've backed the fuel off as far as I can go, and it keeps telling me that I'm still too rich. Please change the O2 sensor for me, because that must be what's wrong with me. Thank you."
