    The coast down spark is stock. Is that what you meant?

    I went out to test it, and now DFCO basically doesn't turn on. It turns on after the pull I did, but then after I get on the gas at 11:00 and...

    I put the rpm limits back to stock and changed what you suggested. DFCO is still going on/off.

    It happens toward the end of the log.

    So I put that table back to stock and nothing changed. I also made sure every DCFO parameter should be triggering DFCO and it is but the issue is still there.

    Would I correct it by putting stock values in the "coastdown" under "idle spark advance"? I noticed those values are reduced compared to a stock ctsv file

    I never asked for a burble tune on the...
  5. Spark timing dropping at low cylinder airmass - 2013 ctsv

    I have noticed that the spark timing drops from 12-13 to 5 then goes back up and it makes the car lunge forward slightly when the converter is locked.
    When the converter is unlocked the rpms will...
  6. First pull on built trans how does the log/tune look?

    The car is a 2013 ctsv, stage 4 6l90 from Circle D, and a Circle D 3000 stall triple disk converter.
    I finished breaking in the trans and I made some changes to the converter based on information I...

    Yeah, I feel like the trans is probably going to have to come out and get torn apart.
    I'll give that file a try soon and let you know how it goes.

    I haven't tested it yet. I'm going to drive it for a little longer just to make sure the trans has enough time to learn.
    Also weeding out the issue of the fluid level possibly being the problem.

    My trans has a modified valve body with the sonax parts from circle d. Wouldn't that affect overall line pressure and give a different reading than stock specs?

    Thank you, I'll give it a try once the lean issue is gone.
    I see just the shift pressures were increased. Will the increase of shift pressure prevent the converter from slipping too?
