On newer cars the enrichment kicks in frighteningly early. My FR-S' stock fuel mapping enriches at 60% load for most rpms. I changed the map, but it's very easy to accidentally kick it into enrichment.

On cars with no wideband sensor you need a bit more load to get enrichment, and old school cable throttle engines would just not enrich the mix until higher rpm (you also get very crap to nonexistent power output below 2000rpm as a result).
