    what table let you adjust coastdown RPM?

    hi there

    2008 stroked z06 with full bolts. When i drive and let of the throttle it seems the car drives on its own, no engine braking basicly. its like autocruise feel, you press no gas but the car drives.
    In final idle airflow i made all values as in neutral/park, but that didnt change much. Wondering how what adjust to get more engine braking when of the gas but in gear. Otherwise car idles and cruises fine.

    Thanks,

    Try playing with the dfco settings. Get the TB and CYL values higher
