DFCO (as my understanding) was part of the OBD1->OBD2 changeover so if your vehicle is newer than 1996 is should utilize DFCO in some form or another.
Here's an OBDII easy reader:

In this case, under DFCO, the momentum of the car via the wheels/drivetrain is running the engine.
Let's see, how would the Chief say it?
Uphill, engine run make car go.
Downhill, car go make engine run.
Well, it was funny in my head. |
ifsofacto....
ur telling me, that when i start my car and start coasting down hill, NO FUEL is being consumed to keep the car running? It runs cause the gear is engaged, and the car is rolling, but no fuel is pumping into the combustion chamber...
Thats what your saying? I suppose the electric spark could be turned off and the engine would still run too then...
If thats what you are saying, and ur right then cool, but it sounds like BS. I'm just sayin...
