If you don't have the IMA, there's little reason to coast in-gear unless you're intentionally using the engine to decelerate. Better to drop it in neutral and use a kill switch in most cases.

I suppose that's also "open loop", but the open loop generally refers to those times before the engine is fully warmed up, and near-WOT, where it's not shooting for 14.7:1 AFR and is instead going for a richer and less efficient mixture.
