Default UEGO problem

My WB is reading 14.7 to 14.8 constantly.. when I rev the motor the gauge still stays the same and continues reading 14.7 to 14.8

Did i do something wrong? I don't see how I could have installed it wrong.

Could this be a result of a exhaust leak?


thanks.

The stock ecu does pretty good to keep your afrs at 14.7. What does your fuel enginemanagement consist of? Are you turbo or still n/a?

I've never used one but i'm pretty sure afpr don't change fuel pressure until they see boost. It's also possible that you have the afpr hooked up wrong. You might want to explain how you have it routed so those that know more about them can help you. Your stock FPR controls your fuel pressure outside of boost so you wouldn't see any changes at idle.

Make sure that the harness that comes up from the sensor is securely plugged into the gauge itself. As long as you have power and ground (which you do because the gauge is powering up, and hopefully going through the default warm-up sequence), the only problem could be the sensor not communicating. With a WBo2, the slightest tap on the gas will make a change in readings.

Something is wrong, my aem uego is extremly fast and detects every single blip of the throttle I give it. Mine uses the entire scale from a free loaded engine rev to 5 grand.
