    Default Serial logging and tuning with 2 LC-1's

    I'm sure I read a post on this a while ago but i can't find it. . . I just got done installing two LC-1 units(one for each exhaust bank) in my 2003 Sierra Denali.

    I have them daisy chained together and connected through a taquickness null modem cable. Is there a way for me to log and AutoVE with both? I'm thinking log them as an average?

    Thanks
    Jesse

    Nevermind, I think I got it worked out in calc.pids

    Post your calc_pids.txt file, let me sanity check it.

    Thanks joecar. I've been away from tuning and EFIlive for a few years and I was new to it then.

    Just tried out the new LC-1 setup and everything seems to be running well in place of the old NB02's. I think I got the PID setup for averaging the two LC-1's but I'm getting no data and this is what it says in "more info"

    PID value cannot be determined because
    the following error would occur:
    List index out of bounds (-1)

    *CLC-00-020
    AFR 10.0 20.0 .3 "({EXT.WO2AFR1}+{EXT.WO2AFR2})/2



    CALC.EXTWO2AFRAV F020 CLC-00-020 AFR WO2-Serial "AFR from Serial WB - 1/2 Average"

    On the end of that line you forgot to place a closing quote.

    Same on the end of CLC-00-021.

    Do you use any of the analog wideband stuff...?

    Also, the calc_pids.txt file needs two blank lines at its end.

    Also, some of the pids were being calculated out-of-order...

    EFILive calculates the pids in CLC-00-xxx numerical order (i.e. lowest xxx first)...

    some of the pids were being used before they were calculated (i.e. their previous frame's value was used in the current frame's calculation).


    I edited your file a little, see attached, please try it and let me know.
