    Default Idle spark enable/disable by VSS?

    Is idle control by spark disabled by hitting a defined speed? I can't seem to find this in the tune. My truck will idle all day in N or in gear stopped, but as soon as I roll down the driveway it wants to stall. Just did a log and found that the stall coincides with spark control of idle shutting down around 4 kmh. I can keep it running by doubling my Desired Airflow table, but then I don't need cruise control anymore.

    Log and tune attached.
