Page 12 Displaying Data with a PC/Laptop Real time AFR and EGT data can also be viewed via a pc/laptop with USB connection. See figure 11. Download the data viewer program and instructions from the AEM Performance Electronics forum at www.aemelectronics.com. Portable Power Connection The AEM X-WIFI has an on-board barrel connector that can be used to power the module using a 5 amp 12Vdc power supply when a hard wired power connection is not desired. The power supply must have a 2.1MM ID X 5.5MM OD plug with the center pin positive. See Figure 12. Connector Pinouts The pinouts for the 6-pin sensor harness, 3-pin sensor harness, and 8-pin power harness are provided below in Figure 13. Figure 12.

The UEGO sensor contains a ceramic module and should not be subject to mechanical or thermal shock or it may be damaged. The sensor is not designed for operation on leaded fuels, doing so will dramatically shorten sensor life. Long term running in the rich region (Lambda < 0.95) will shorten sensor life. High exhaust temperatures (over 850C) will shorten sensor life. Engine oil consumption at a rate greater than 1 quart per 1,000 miles will shorten sensor life. With the UEGO Sensor installed, do not run the engine without power applied to the X-WIFI.
