It has DFCO, they have sense the 80s. You can feel the injectors cut back in when you slow down.

When you get an Ultra gauge you have to tell it if you have DFCO. If you have told it you have dfco it calculates fuel burn based on it when the throttle is closed and the engine goes into open loop. The ultra gauge does not know anything about the status of the injectors. It knows fuel consumption based on air flow. To tell if you have dfco by the gauge you need to have the O2 sensor gauge displayed, it will go full lean on dfco and the loop indicator will go open.
