    Setting up $0D Open Loop Idle only - Closed Loop Off Idle...

    I don't have a rig here to test this so maybe someone knows, what I think I remember?

    I want Open Loop for Idle only in $0D. Go closed loop Off idle. IIRC it has to do with these 2 paremeters but forget what or which way? You can see it is set for Closed Loop Idle as well right now.

    1. Title: Open Loop Enable Timer

    Location: 48D4

    Usage: Open Loop Qualifiers

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

    2. Title: Open Loop Idle Temperature Threshold

    Location: 48D8

    Usage: Open Loop Qualifiers

    Tips: Threshold to remain in open loop idle.

    It's more complicated than that. Please see this PDF: https://drive.google.com/file/d/0B-3...ew?usp=sharing

    It discusses many of the key engine parameters and explains them better than the XDF.

    Thank this is what I was looking for.

    So basically by setting the Initial spark to 10, it seems to offset the mechanical adjustment I made. I am trying to figure out my surge issue I have under part throttle. Man the GM TBI system is giving me so many headaches.
