The delivery time depends on us having the correct .a2l for the current map you send us. Feel free to send us the map in advance to be sure we can help you.
Mappack is actually a .kp file (WinOLS format) that describes map location, factors and axis for maps. It can be imported/exported directly from WinOLS (full version). For example you have a project with defined maps and you want to create a new project for same ECU in other place, you can export .kp mappack and import on second location to have same maps/factors in both places.
