Ok I am not sure that this goes here. When I was hooking up my AEM to data log it I searched and searched and found nothing that really helped. So I spent a couple days messing with thing till I got it to work. So here is my Write up.

First get your fire wire cable and whack an end off (needs to be a 6 pin). Now you should have a Red, White, Green, Orange, Black and Blue.

Next go here http://www.tricktuners.com/data_logging_info.htm (http://www.focusfanatics.com/forum/redirector.php?url=http%3A%2F%2Fwww.tricktuners.com%2Fdata_logging_info.htm) they have the pin out correct but the colors may be off I performed a continuity check to get the colors correct for the pins.

Once you have the color combination ground out all three Grounds (in my case it was black, orange and red). Then hook up the analog 1 wire (which is pin 3) from the fire wire to the white +5 wire from the AEM gauge.

You now must go in to your X3 and set up your analog reading.http://i198.photobucket.com/albums/aa82/gonefhsn/Datalog%20Help/IMGA0050.jpg

Plug in your fire wire cable and start the car

once you do that you will see the wide band registering on your X3.

This next portion is if you want to data log using Live Link Software.
Once you have that shut the car off open live link, hook up the Xcal to your laptop using a USB Cable, Turn the key two clicks (do not start car) Hit the little graph up in the top left corner and the system will connect to your car and open the select signals menu select your signals, make sure to select analog 1 so you can get your analog readings. After you made your selections hit ok.http://i198.photobucket.com/albums/aa82/gonefhsn/Datalog%20Help/PIDS.jpg
You must select other PIDS or it wont read (at least I did)
Now you must go to the commands tab, select analog equations http://i198.photobucket.com/albums/aa82/gonefhsn/Datalog%20Help/commandtab.jpg
Check the block behind Analog 1 EQ, use the drop down to select AEM then apply change, ok.http://i198.photobucket.com/albums/aa82/gonefhsn/Datalog%20Help/Equation.jpg
Now when you start the data logging session if you get this error just hit ok

Start the car you will be able to see your wide band registering in live link with the proper A/F reading.

If you do not set the equation all you will see is a voltage reading. And your tuner needs the proper A/F reading for data logging. Hope this helps you guys out in hooking up your AEM UEGO. Now this may as well work with with other UEGO Gauges but I can not say since I have an AEM one.

Not a bad write up. What made you deside on the AEM as opposed to the others. Just curious.

A recommendation

Too bad this doesn't work for 2008+ ECU's :(

why won't this work for the 08s+? i jsut got my x3 in the mail and i have already installed my aem wideband.

do you just have to use a different equation?
or is it just some stupid ecu problem?

They say it is a ecu problem. But i dont understand why when this is an analog connection to the x3

Nice write up, Josh. Nice to see you finally got it to read right. Do you still need to do the WOT datalogging?

Nope it is all dialed in

Sweet.

Not to down you but there was already a write up that shows all of this. but still good write up

where is it? I searched all over this site and FJ looking for it and could not find one. But if there is cool

NOT TO JACK THIS THREAD...........does anyone have a tutorial to datalog using xcal2?
(aem )

yeah there is a how to and everyhting search for it in this forum

http://www.focusfanatics.com/forum/showthread.php?t=202640

thats the link to it

gonefhsn- hey i will post a link whenever the stupid search button wants to work

cool thanks.

I found it

http://www.focusfanatics.com/forum/showthread.php?t=177202

I tried that one and it did no good for me, the X3 is an older version. But thanks

It didnt work for you? what went wrong

I found it confusing and the stuff in my X3 does not match his X3.

O ok cool wonder what the difference is

I'm going to try and hook my aem wideband upto the xcal2 today wish me luck

Marty its a bitch but good luck
