    But this won't work:

    AFR 10.0 20.0 .3 "{EXT.AD1}*2.3750+7.3125"
    LAM 0.5 1.5 .3 "{CALC.AEM.AFR}/14.7"
    EQR 0.5 1.5 .3 "1/CALC.AEM.LAM"



    #Code PRN SLOT Units System Description

    CALC.AFR-WO2BEN.AD1 F110 CLC-00-119 factor "W02-Ben" "AFR BEN AEM"
    CALC.AEM F001 CLC-00-2058 "V,AFR,LAM,EQR" WO2-Analog "Wide Band AEM"
    CALC.BEN.AEMAD1 F110 CLC-00-2060 factor "W02-Ben" "AEM BEN from Lambda"
    What error does it say...?

    You're using CLC numbers -2058 and -2060... they propbably should be 3 digit, and that have to match the CLC that you edited.

    Also, you're reusing the F number, F110 is used twice.

    Also, for CALC.BEN.AEMAD1, you can't use a name like that, too many dots, try CALC.BEN_AEM_AD1
    And instead of units factor, you probably meant LAM.

    And for CALC.AFR-WO2BEN.AD1, you can't use "-" in a name, try CALC.AFR_WO2BEN_AD1, or better CALC.WO2AFR_AD1 (since AFR and BEN are two different things).
    And instead of units factor, you probably meant AFR.


    Code:
    CALC.AEM         F001 CLC-00-xxx "V,AFR,LAM,EQR" "WO2-Analog" "Wide Band AEM"
    CALC.WO2AFR.AD1  F119 CLC-00-119 AFR             "W02-Ben"    "AEM AFR"
    CALC.BEN_AEM_AD1 Fxxx CLC-00-xxx LAM             "W02-Ben"    "AEM BEN from Lambda"
    




    Post your edited calc_pids.txt file, let's fix it.

    Attached is the calc_pids I have that seem to be working but with all the problems you've identified. I'm using LS1B only.


    On a separate topic I'm finding that the voltage being logged is too low. The wideband gauge is showing reasonable AFR's of 14-15.5(lean cruise) but according to the voltage being logged the engine is running rich. The equations on the calc_pids.txt are the correct equations according to the AEM manual. I'm thinking I may be getting too much voltage drop between the gauge and the V2. I'm using two wires out of a CAT5 cable for the AD1. Is there a recommended gauge for the analog voltage? Attached is a log, the gauge was showing around 14.2 AFR at idle at the start of this log.

    flip the wires around on the ad connector. i found this out the other day that if you wire it wrong. it'll still work but the voltage is different.

    i also use ad4 on mine simply because the first couple of ad's always have some sort of voltage reading on them. even on a couple of different v2 units

    That did the trick, I will checkout my other analog ports to see if they have voltage when not being used.
