    Cheers.
    Ok, I see...



    In the integrated wide band O2 images:

    *

    "AFR :1" is the PCM's commanded Air Fuel Ratio.
    *

    "WO2 AFR" is the wide band O2 sensor Air Fuel Ratio.
    *

    "O2 SIM V" is the wide band O2 sensor's simulation of the narrow band O2 sensor.



    Can you elaborate more on it? Or is that just saying that EFI Live now comes with the PID's already pre-configured, but I will still have to hook the wideband up as described above? Thanks....

    do you have to have the complete LM-1 to do this or can you just use the sensor? I've got a wideband sensor the wires are RED YELLOW GREY BLACK WHITE.

    It's the BOSCH sensor that comes with the LM-1

    Sorry I just saw this. You have to have the complete LM-1 for this to work.

    Thanks to JNorris and Blacky for the help on this. I have a Zeitronix Wideband and finally was able to incorporate it into EFI Live. I have a 02' and the colors for the A/C harness were a little different. Red/Black, Gray, and Purple were the colors for my car. I took the output from the Wideband (white) to the Red/Black on the harness. Next, I took the Brown wire (sensor ground from the wideband) and taped that into the purple wire on the A/C harness. This was the easy part.

    Onto the PID. This took several attempts to get correct. Here is the current Custom PID that I am using. I have compared this to the actual Dataloger on the wideband and it is spot on. I'm not saying this is the right way, but it works. :lol:

    I have a dynojet wideband commander and I used your cal pid. Everything works great but it read 28.something when the afr is 14.7. Can anyone explain to me how to fix this in laymans terms.

    THanks a ton,

    Do you have any specifications from Dynojet about the relationship between the output voltage and the AFR value?

    For example, some wide band O2 manufacturers state something like this:
    0V = 10AFR
    2.35V = 14.7AFR
    5V = 20AFR
    Does your dynoject have any similar specifications?

    Regards
    Paul

    I called tech support, and they said

    0v = 10-1
    2.94v = 14.7-1
    5v = 18-1

    Thanks

    That would make your wide band O2 equation:

    AFR = V*1.6+10

    so in this http://www.efilive.com/forum/viewtopic.php?t=1145 example, replace
    Code:
    # ==============================================================================
    # Add slot definitions here
    # --------------------------------
    # See sae_generic.txt for more information on "SLOT" formats
    #
    #Units             Low          High      Fmt  Expression
    #------------ ------------- ------------- ---- --------------------------------------------------------------
    *CLC-00-001
    AFR               10.0          20.0       .1  "{EXT.AD1}*2+9"
    with
    Code:
    # ==============================================================================
    # Add slot definitions here
    # --------------------------------
    # See sae_generic.txt for more information on "SLOT" formats
    #
    #Units             Low          High      Fmt  Expression
    #------------ ------------- ------------- ---- --------------------------------------------------------------
    *CLC-00-001
    AFR               10.0          18.0       .1  "{EXT.AD1}*1.6+10"

    Paul, I'm using the same thing as jnorris in the first post. Basically I need to use a different formula, but I am braindead and can't figure out how to do it.

    I'm using my analog output voltage to go into my a/c pressure sensor with V6.

    Your right my afr=v*1.6+10

    Thanks
