    Idle Tune

    Well i read till my eyes are popping out LOL . Tuners i'll come out an say it need some advise/help . I have some issues with spark advance or it think that is the issue going from park to drive an visa versa almost likes to stall but recovers same when coasting . I think it might be my octane tables need some altering around my idle cells . Free revving the idle likes to hang also but recovers just not quick . Here is a small data log driving around the block an current file . 2011 Gen IV 5.3 with mild cam -10 degree overlap SUM-8719R , cast block , aluminum heads .

    Well this did work engine/idle/base set point ; 750 Rpm
    engine/idle/start up ; set the RPM around the cells to suit above
    engine/idle/ in gear ; same as above
    engine/idle/minimum set point ; same as above
    engine/idle/airflow/throttle follower ; set to 100 nM @ 800 RPM / set up scanner to read PID
    engine/idle/rpm/start up ; p/n set the RPM around the cells as in base point set
    engine/idle/rpm/in gear ; same as above
    engine/idle/rpm/minimum set point/VSS ; same as above

    Any feed back as to what i did good or bad
