The mapping can be done in both modes as long as transients are observed and all other standing corrections are factored into the calibration to get a true error/correction required. Typically it is not possible to do closed loop mapping since the ECU will enter open loop with AFR targets outside of the 14.7 range (anything 14.69 and below will trigger open loop).
