    Ok, I applied the LC-1 AFR/BEN calc pids, and your actual AFR got better, it's closer to commanded AFR...

    but, if VE/MAF/IFR were dialed in, actual AFR would [pretty much] track commanded AFR closely.

    Is it still unsafe?

    Also.. It has Speed Density so the Maf isn't plugged in

    I would investigate that knock... especially if you use nitrous.

    For nitrous you need AFR as rich as low 11's, but I'm not an expert on nitrous.

    You can't hear it knock...?

    You may want to check/replace your knock sensors and knock sensor subharness; do you get any DTC's...?

    Have you been tuned for your mods...
    in particular:
    - injector need IFR table to be recomputed;
    - cam, intake, tb need VE table to be dialed in;

    Do you calibrate your LC-1 (heater cal, and then free air cal)...?

    I think your timing's too high (again considering nitrous) and your AFR is a little lean in some places.

    I just bought this car last weekend... This software was included and the guy seemed knowledgable about it. I just want to make sure the tune is good. Im a total newb with Efi Live. I don't remember hearing any knock.. I guess I could pay a little more attention to it.

    I tried to pull my tune but it said it couldn't read the pcm. Im updated Efi live so maybe thats all it is. I'll load it up when I get it

    Read the LC-1 manual and follow the heater cal and free air cal procedures:
    http://www.innovatemotorsports.com/s...C-1_Manual.pdf

    Do you have the DB-9 to stereo connector for connecting the LC-1 to your laptop...?

    Download this version of EFILive software (download the zip, follow the instructions on this page):
    http://forum.efilive.com/showthread.php?t=5707


    It may be a combination of a little too much timing and valvetrain noise.

    Do you have EFILive FlashScan V1 (has no LCD) or V2 (has LCD)...?
