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.

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.
