Hi Guys.

Hope someone can help me out:

I notice the display on the AEM UEGO Wideband guage consistently reads 0,5 LEANER than what the ecu says the air fuel ratio is at. Be that WOT closed loop sitting idling.

Which one do I believe?

What could be the possible cause of this?
The AEM sensor is in the downpipe at the top near where the turbo is.

I was thinking possibly air leak...maybe between MAF and turbo? maybe?

The sensor is in the right place, Is there anyway to recalibrate the sensor, I know you can on the Innovite LC-1 but not sure about the AEM ones?

I would rather believe an aem wideband than the ecu reading of a std narrowband o2 sensor. These two sensors are not going to read the same due to their differing designs and where each one is placed.
