    Default Logging AEM wideband issues

    So I've realized my stregnth is with turning a wrench and not tuning. Black Bear is doing my tuning but I'm trying to get logs for him. I have my calc_pids set up for my wideband
    as follows

    # ================================================== ============================
    # Units
    # -------------------
    # See sae_generic.txt for more information on the *UNITS section

    *UNITS

    #Code System Abbr Description
    #-------- ---------- -------- -------------------------------------------------------------
    AFR1 NONE AFR "Air fuel Ratio"



    # ================================================== ============================
    # Add slot definitions here
    # --------------------------------
    # See sae_generic.txt for more information on "SLOT" formats
    #
    #Units Low High Fmt Expression
    #------------ ------------- ------------- ---- --------------------------------------------------------------
    *CLC-00-0018
    V 0.0 5.0 .1 "{EXT.AD1}"
    AFR1 8.0 20.0 .1 "({EXT.AD1}*2.375)+7.3125)"

    CALC.AFR_AEM F018 CLC-00-018 AFR 02-wide "AEM Wideband - Input 1"

    In v7.5 scan I can see it under Pids (f8) and select it, but under data(f9) it still doen't show up. Justin gave me a .pid file to log with and I added that calc pid as follows, but it still doesn't work. I have verified by looking at the analog inputs on the V2 I can see the voltage moving around under AD1. Any advise or help?

    CALC_AFR_AEM=1,-1
    CALC.FPS=1,-1
    CALC.INJPWDC1=1,-1
    CALC.POWER_RW=1,-1

    When you select it, does it have a red X thru it...?

    You also have to select EXT.AD1.

    It does not have a red x through it, but Ii did not select ext.ad1. Let me try that updated calc_pid and also select ext.ad1

    I'm able to log AD1 just fine when I added it, I updaded my calc_pid to what you posted and my wideband pid still won't show up under f9 data, yet I can select it and there is no red x under f8 pid.

    On the Data tab, click twice on the Heading of the first column...

    then post screenshot of the PIDs tab and the Data tab.

    What is weird is the PID shows a different name than what I used in the calc_pid file.



    I ended up openeing the sae_generic file and changing the scaling of one of the preprogrammed WB02's in there to match what i needed. I am able to log that so the end result is what i wanted, just still curious why i couldn't add another.

    Weird...

    in the screenshot, I don't see EXT.AD1 selected on the PIDs tab (and I don't see it on the Data tab).

    What V7 build version are you running (Help->About)...?

    Ok, it looks like your calc_pids.txt file (which I edited and pasted above) is missing some heading stuff...

    see attached...


    ( it is better to attach the calc_pids.txt file rather than to paste its contents )


    ( should not have to edit sae_generic.txt... if calc_pid.txt is not working then it is incorrect )
