    Default LC-1 reading too rich...how program it to correct?

    Hello, I'm using V7.5.7 build 180. I programmed my LC-1 by following the instructions in the EFILive LC-1 Installation Tutorial and I have a strong suspicion that I need to correct the way the I programmed it and I need some help. My readings seem too rich. I followed these instructions to program it for EFILive:
    "Set the Analog Out 1 to the following:
    a. 0.88333 Volts at AFR: 10.00
    b. 4.21667 Volts at AFR: 20.00"

    However I noticed that these instructions are for V7.3, and I'm guessing that is why I seem to be getting readings that are too rich:
    "Programming LC-1 for EFI Live
    EFILive version 7.3 has an LC-1 calculation in the “sae_generic.txt” file. The LC-1’s programmable settings in this section are based on these calculations. If your file is different, different input values will be needed for the LM Programmer.
    # Innovate LC-1 WBO2
    # ========================
    *CLC-00-926
    V 0.0 5.0 .1 "{EXT.AD1}"
    AFR 10.0 20.0 .2 "({EXT.AD1}*3)+7.35"
    *CLC-00-927
    factor 0.0 2.0 .1 "{CALC.AFR_LC11.AFR}/{GM.AFR}"
    *CLC-00-928
    V 0.0 5.0 .1 "{EXT.AD2}"
    AFR 10.0 20.0 .2 "({EXT.AD2}*3)+7.35"
    *CLC-00-929
    factor 0.0 2.0 .1 "{CALC.AFR_LC12.AFR}/{GM.AFR}"

    Could someone help me out with the correct way for me to program the LC-1 for V7.5.7?
    Is that my problem? Or am I on the wrong track?
    I don't know how to find the sae_generic.txt file referred to in the instructions.

    Default

    The LC-1 pid expression, "({EXT.AD1}*3)+7.35" is for the default analog values.

    5v = 22.39 afr
    0v = 7.35 afr

    If you change the LC-1's analog outputs you will need to change the pid expression.

    Leave the sae_generic.txt alone and return the LC-1 outputs to factory default or
    create a calc_pid based off the stoich afr in the pcm the LC-1's programmed Lamba output.

    How to match wideband output to {B3601}

    What vehicle & OS?
    512k RoadRunner Firmware 12.14R
    FlashScan V2 Bootblock V2.07.04 Firmware V2.07.22 EFILive V7.5.7 (Build 191) V8.2.1 (Build 181)
    LC-1 WBO2
