Hi Tom,
It depends on the calibration strategy of the system.  Adaptive learn is 
not only used for changes in engine characteristics, but also used for 
changes in fuel composition.  If the adaptive learn number is intended to 
correct for fuel composition, it may be applied to the fuel calculation 
in open loop mode as well.  The only way to know for sure is to hook up 
the Tech tool and find out if BLM (block learn) automatically goes to 128 
(no correction) at WOT.

Best Regards,
