Thread: AEm Uego Digital wideband users

Ive had mine in for about 2 months or so. I drive my car maybe 40 miles a week at most. So it doesn't get much use. Anyways the Gauge was reading perfect at idle Id get 14.6-14.9ish bouncing around, Now Im getting 13.2-15.3 with it going to ---- (max lean) even when its reading in the 15's. Anyone have a issue like this? WOT it reads 11.7 like it did before pretty consistent but every so often it will jump to 13.8ish like its osculating.

Err, I think I found the issue, I went out to pull the sensor and do the wrap in a rag trick. I unplugged the sensor, looked at the gauge. Instead of reading 14.7-14.8 the numbers were osculating all over the place. SO im ASSuming its an actual gauge related issue

They dont need calibration. The sensor itself is calibrated before you even get it.

.
"Each AEM UEGO sensor is individually calibrated and a resistor integral at the
connector body is laser trimmed with this value. This process replaces the traditional
“free air” calibration procedure when changing sensors and implements a sensor

specific calibration for unparalleled accuracy."

http://tunertools.com/prodimages/AEM...structions.pdf Theres no real way to calibrate it that I can see. This is the only calibration you can do is to change the values it reads

The AEM default position is (P0). When set to (P0) (Figure 10A), the gauge displays
AFR values. (P1) is the same as (P0), except the gauge displays lambda values. These
settings (P1 and P0) implement a linear calibration with the most useful voltage range
possible (0-5V). The AFR calibration (P2) is linear and similar to (P1) with a smaller
voltage range (1-2V). The AFR calibration (P3) emulates the Autronic Wideband O2
Sensor calibration (0-1V). The AFR calibration (P4) emulates a non-linear Nernst Cell

calibration (0-1V). Refer to the Table 3 and figure 9 for specific calibration details.

edit, I figured it out, I was doing something stupid...as usual
