Hello, I'm a noob about this, so please sorry my ignorance. I have the AEM UEGO Inline (no gauge) wideband, I have it installed on my Cobb downpipe, I want to log by serial port, I know in the inline version I need to hook up the grey wire to a serial connector.

I'm attaching some pictures of what I've done, is it ok?, I'm doing something wrong?

When I connect the serial to usb to my laptop and open the AEM Monitor I clic on Connect using COM3 (which is the correct one) but it doesn't connect.
I'm using Windows 7 and have installed all the drivers for my serial to usb connector.

Please I need a little help.

 

I finally solved this, I'll post the solution in case anybody is in the same situation. My ground was bad, I grounded to the same ground as the UEGO.

The AEM serial Monitor doesn't work at all, but I was able to log AFR with this tutorial on COBB Access Tuner:
