Yeah, the older the FI car, the less likely it has DFCO (deceleration fuel cut off). I am pretty sure my car does not have it either. With my digital AFR (Air Fuel Ratio) gauge, I can see the AFR go lean when I hit the brakes, but the lean condition doesn't last for the whole brake event, it goes back to 14.7 . This implies to me that the engine is still getting fuel. Also, when you brake in-gear and you approach idle RPM, the fuel is restored to avoid stalling the engine.
