Help with AF-readings. Stock Fuelsys. and 16g.

[Chris_Sag]

I have installed a AEM-uego and is running 16-17psi on a 16g (Xs-power).
When i floor it my readings is around 10,2-11,4-1 and the light is always on green. When daily driving the orange light is on and reading 14,1-15,7.
When idling the light becomes red and it lies around 17-1.

How is it possible that I am running rich at stock fuelsystem and a 16g running 16-17psi? Something must have been done to the car in the past?

I cant be ok under boost if I still have standard injectors:S When idle it runs a bit high between 1100-1400rpm..

If you don't believe your wideband try recalibrating it.

 

[Chris_Sag]

Is it a vfaq here of how to calibrate the wideband?

Your sensor should have came with a paper describing how to recalibrate it. Most need calibrated before you install them.

I could tell you how to calibrate the LC-1 but not sure on the UEGO. Might be instructions on AEMs site but there should be enough members on here running one to tell you how to do it.

Dont understand mutch of the paper to be honest. But mostly it is tabeles for calibrating EMS..
