    I'm not at home to can't check your tune now to see where it actually is, but mine is a lot happier running slightly rich at tickover.

    are you sure about that Jim?

    Also, I went to log today and for some reason all of the PIDs in my list had a red X through them except for the calculated PIDs. Would anyone know why it would be like this?

    I think im done with this MAF stuff and im just going speed density. I think having this big cam and a fast 102 just makes it hard to run stable and at the right A/F. I have to learn speed density regardless when I go to turbo so might as well learn it now. If i drive in 70 and 90 degree weather should I be ok with speed density? Also, which should I tune in?

    I think before I tune I should switch my timing tables back to the z06 tables except for where it idles as my engine more resembles an ls6 than an ls1 and I noticed a difference last time.

    Jim, the second one is inverted.

    Edit: Sorry, my mistake: I meant to say "those are inverted".

    Check the following:
    - File->Select Controller shows correct PCM/ECM.
    - File->Enter VIN.
    - Info->Validate Pids.

    if the second one is inverted wouldn't the first one be inverted as well.

    My VIN was not entered correctly for some reason. Thanks.

    What I decided to do was use CALC MAFT and compute my VE values with no MAF. I will be doing this calculation with only using my wideband sensor.

    What should I do to my CALC PID file from before? would it be the same as my calc vet PID file?

    By the way I will be running OLSD. Is this a bad idea?

    More questions I hope someone can answer these

    b3618(PE modified based on RPM), I was reading the AutoVE tutorial and it said to make these stoich for OLSD. It also said to make my VE table 15% rich. I understand the VE part but I do not want my PE table to be stoich above 3200 RPM. Is this correct and does the rich VE table allow me to do this?

    I also looked at what theys said the COS 5 A/F table should look like and it was only rich above 80 KPa in MAP and below that pressure it was stoich for all RPMs. wouldn't I run into detonation problems for 6400 RPM, 60 KPa Map, and stoich?
