hey EVeryone,

i installed my A/F gauge and i tried hooking it up to the white wire on my ECU, and i get a response and all on my meter but at idol it flys from lean to rich by its self. and when im at full throttle it sometimes is at stoich still.....im confused i tried hooking it up to the white wire running from my O2 sensor out of my exhaust but it did the same thing. idk what to do??? is this suppose to happen or is my computer F*cked?

 

That's what it's going to do. Not very accurate as you can see. This is why wideband O2 sensors are much easier to work with.
