    The serial connection avoids ground offset problems that seem to show up with the analog connection.

    Also consider this: the wideband controller contains a cpu/mcu which drives the actual sensor and computes lambda/afr from the sensor's response... the controller then emits the lambda/afr via the serial comm port, and simultaneously maps it to analog voltage via the programmed afr:v map and emits this voltage via the analog output (only for it to be unmapped in the scantool)...

    i.e. the analog connection involves extra manipulations in mapping/unmapping the afr.

    The serial afr is more precise than the analog afr, especially if the analog v:afr map is too broad (e.g. 0-5V -> AFR 0-50).

    It's quick and it's easy, and as Joe has said, more reliable. I'm still an apprentice with this tuning game, so anything that is quick and simple is a must for me.

    I'm using the AEM UEGO WB connected through serial Comms.
    I got the new Calc.pid.txt downloaded and coppied to the right folder and it appears in the PID list. I selected it and connected to vehicle and the Comm. port for the WB. Then validated the PIDs and it still is X'd out. Any ideas?

    Thanks,

    Figured it out, I needed EXT.WO2LAM1 selected for it to work. I had EXT.WO2AFR1 selected instead.

    Thanks,

    Hi Brandon, good job on figuring it out

    You will notice that we now try to use GM.EQIVRATIO and EXT.WO2LAM1 and/or EXT.WO2EQR1 (which is defined as 1/EXT.WO1LAM1) for various reasons:

    - we found that GM.EQIVRATIO seems to follow the command fuel tables more closely than GM.AFR,
    - this makes tuning not rely upon stoichiometric AFR.

    hello,

    I have the AEM inline wideband UEGO controller, part # 30-2310. when i hook it up to my V2, there is data traffic as indicated by the flashing LED, but if i select to display W02, it doesnt see anything.

    Serial hookup is used and wiring is correct to my knowledge.

    Any suggestions?

    Matt

    Which V2 firmware version/date do you have...?

    Did you set the comm port to Wideband, and set wideband type to AEM...?

    Can you use EE/HAPI to capture a shot of your V2's LCD...
