    Default AEM wideband to FlashScan V2

    Hey all,

    trying to hook up my AEM UEGO wideband into my buddies FlashScan V2 so we can log the wideband's output. I've read a bit and wanted to verify before making cables/blowing anything up.

    Alright, so, from the AEM gauge, I'm going to run the blue cable (serial output "Connects to a RS-232 com port for hyper-terminal data logging") to pin 2 on a DB9 serial connector. The gauge already has power/ground.

    Now, the FlashScan V2 serial cable (seen here) has a female end. Am I right to think that I can simply wire the blue wire into pin 2 of a male serial cable, connect this to his FlashScan DB9 to RJ12 adapter, into the FlashScan handheld, and then have logging capabilities?

    If I'm incorrect, please let me know. Need to iron out some part throttle/idle stuff so I stop getting 11MPG in a cam-only 2940lb car

    I am trying to do the same.

    Which AEM Uego?

    Mine is as follows:
    Part Number 30-2310 AEM UEGO CONTROLLER

    Here is the wiring diagram for mine.

    I am trying to wire it with the RJ12 connector (into top of V2) using pins 2 (to Uego Grey) and Pin 5 to Uego Brown. So far no luck.

    You need to use the grey and black, not the grey and brown.

    Picked up the male DB9 connector and hood last night. I'm going to build the cable today and I'll report back with results.

    Any one get this working yet?

    So far I have a

    Uego connection to Car or RJ14

    Red to Switched hot in car
    Black to Ground in car
    Grey to red position 2 on RJ14
    Brown to Orang position 5 on RJ14
    White taped off

    This does not work. According to IRA's suggestion, I loose the brown and this should work?

    Default 30-2310 aem uego controller

    According to the instructions that were posted:
    PHP Code:
    The grey wire from the UEGO Controller outputs the data stream in an RS232 serial format
    To connect to the pc/laptopan RS-232 DB-9 connector is recommended
    The grey wire from the UEGO Controller goes to pin 2 of the RS-232 DB-9 connector
    Pin 5 of the connector goes to groundSee Figure 5.

    Is it possible to go direct RJ 14 into the top of the V2, eg grey to position 2 on RJ 14 and then RJ14 position 5 to ground? This leaves the white Uego and brown uego hanging.

    Also, will this configuration, if it will work, only work with the PC connected to V2, rather than V2 acting stand alone?



    PS, tested putting RJ14 position 5 from V2 to ground in addition to Grey AEM to position 2 on RJ14. This does not work. V2 reads "WO2 not found".

    Also, does the above diagram depict:
    White AEM to V2's A1 plug at bottom and AEM brown to A2? Would the V2 still need a wire at the top? Grey AEM hooked up to the RJ14 connector?

    The serial wire goes to pin 2 on the rj12.
    You may also need to connect a ground to the rj12 pin 5 but the AEM instructions do not call for this.
    If using the analog wires they will go to one of the AD input sets. (positive & negative)

    ____RJ12______
    1 = Tx Data
    2 = Rx Data
    5 = Ground

    You will need to select the WBO2 manufacturer in the V2's internal settings too.

    So AEM Grey (serial??) to position #2 on RJ14 cable. This with a switched car hot to AEM red and AEM black to negative gives me a flashing light on V2.

    Are "AD" input sets the ones on the bottom of V2?
    Do I need AEM white to A1 and AEM brown to A2?
    Does this need to be done in conjunction with the above or as an alternative to it?

    Thank you very much for the help. Noob here.
