So if using the RJ14 (6 position) plug to V2, which position goes to TX and RX? Positions 1 (black) and 2 (red)?
I believe a white wire goes to position 5 on the RJ14 plug. Not sure if this comes into play.
I can call AEM and find out which wires are TX and RX respectively on the AEM unit itself.
Thanks.

Yes, pins 1 and 2 on the RJ12 plug.
Pin 5 is ground, you need this.
The AEM directions call for the GRAY wire to be connected to pin #2 of a RS-232 DB-9 connector.
The cable that comes with the V2 has a DB9 end and an RJ-11 end.

_2 <-> 1_Rx
_3 <-> 2_Tx
_5 <-> 5_Signal Ground

hello,
I have the same problem
the display show W02 NOT FOUND
ii have tried every wire combination and still no luck, the sensor is grounded, my yellow light is flashing, the green light on the UEGO controller is on
im lost
serial out from AEM UEGO module, grey wire, to RS232 on Flashscan, i tried both pin 1 or 2 of the RJ-11
Brown wire to #5 of RJ-11 and to vehicle and ground
Power as per AEM manual. I have tried the ground wire any way, just to RJ-11, Just to vehicle ground, not hooked up etc
The yellow light on the V2 flashes as there is something going on, but nothing.
I set up the Flashscan with Efilive Scan and Tune version 8.2.1, build 170. i went through all the settings, like i said, im lost
Thanks
Connect like this:
AEM grey wire -> RJ11 pin 1
AEM black wire -> RJ11 pin 5
The black wire also goes to vehicle/battery ground.
Do not connect the brown wire to anything (at all)(tape it off);
Thanks, But i'm pretty sure i tried that, i will give it another try
by black you mean the sensor negative that comes in the bundle of wire? white (EUGO 0 - 5v) , Brown (analog -) and Grey (RS232) or do i run a separate ground wire and just use only the
grey one out of the bundle?
I have AEM Part number 30-2310
Thanks again
