That's strange. Admittedly the Insight is not a "normal" car, but the only time I see it going into open loop (other than briefly on a cold start) is when coasting in gear with zero load, or even regen. The MPG bar is always pegged at 150 mpg when this happens (though it can be pegged in closed loop, too), so I always thought it meant the engine was in DFCO. Enrichment with the fuel cut off doesn't make sense, does it? Or is this just Insight weirdness? (It's the only thing I've ever driven with a ScanGauge or similar.)
