    Thanks, it took slightly more that 1/4 turn and she's bouncing between 12-18. Idle is a tad lower now too, bouncing around it's set point.

    Ok New Question

    I currently am forcing open loop mode with a high closed loop temperature. How do I make the PCM do open loop idle and closed loop everything else?

    Under IAC Parameters: Closed Loop Idle - clear checkbox.
    Under Open Loop Qualifiers: Change qualifiers to meet your needs. Example: Open Loop Enable timer - 1 second. Below is the XDF info for the timer parameter.

    Title: Open Loop Enable Timer

    Location: 48D4

    Usage: Open Loop Qualifiers

    Tips: If time greater than setting, enable open loop idle.

    Conversion: Sec. = 1 * X

    That thread is incomplete. But I found a reference that I would consider crucial. https://drive.google.com/file/d/0B-3...ew?usp=sharing
