I've personally never found a car that went open loop at 80% load. My Renault will go open loop at 100% load plus a bit more pedal. My Wrangler will only go open loop above 90km/h. Even with an older car and MPGuino I didn't see enrichment at full load.
My Fiat will stay closed loop at all loads/ speeds. I suspect it does enrichment even though the loop indicator suggests closed. For the other cars, I believe the loop indicators to be correct.
