Displaying Data with WIFI Enabled Electronic Devices
Real time AFR and EGT data from the X-WIFI can be viewed on WIFI enabled
electronic devices using a standard web browser. Locate the network “AEM X-WIFI”
and connect. Type the address 192.168.3.88 in the address bar of the browser and
open the web page. A screen showing the AFR and EGT values will appear as shown
below in Figure 2. If a UEGO
sensor error is detected, the AFR value will display “Err”
followed by a number. The number corresponds to the number of flashes on the error
status light as described in the Status Lights section below. Visit the video gallery at
www.aemelectronics.com for information on configuring specific WIFI enabled mobile
electronic devices.
UEGO Sensor Mounting
A weld-in M18 X 1.5 UEGO bung is supplied for sensor installation. Mount the UEGO
sensor in the exhaust system at least 18 inches downstream from the exhaust port. If
you anticipate high EGT's (over 800C), run a turbocharger, run at high RPM for
extended periods of time or plan on running leaded race fuel then you must mount the
sensor at least 36 inches or more downstream of the exhaust port as all of these can
cause the sensor to overheat. On turbocharged engines the UEGO sensor must be
installed after the turbo charger, if not, the pressure differential will greatly affect
the accuracy of the unit. For accurate readings, the sensor must be mounted before
catalytic converters and/or auxiliary air pumps. To prevent collection of liquids between
the sensor housing and sensor element during the cold start phase, the installation
angle should be inclined at least 10° from horizontal with the electrical connection
upwards, see Figure 3.
