Does it matter if I drive around with the cel for a while also ?
You're fine to drive around with cat ineffeciency codes until you can get the AP installed. Once the AP is installed any of the OTS stage 2 or stage 2+ maps will get rid of the CEL. Using ATR you can also disable the OBD2 readyness checks for any of the maps if you want.
