we dont have access to specfic ecu maps.when we reprogramme it uploads the latest software applicable for that car/computer.you cant get around it because you have to put the original vehicle details in as well before it lets you carry out any programming.the 182 has other differences as well.most of the power gain is not from the ecu in fact the 182+172 computer maps wont be that much different.you can easily gain 10bhp on your 172 by doing a few mods anyway.
