If I remember correctly from the SG manual. It does not exactly "read" DFCO. It "assumes" DFCO when RPM is greater then some value and TPS is 9. You really have to feel it in your rear end to see if your going into DFCO. As the RPM coasts down to 1200 or so I can "feel" the injectors start back up because the deceleration "engine breaking" is not as great.
