Very complex stuff gone in to the Revo code to make it switch with the SPS tool, We can offer the Power gate tool to switch out remaps.
For the the TDIs we are going to start to offer vagcom map switching which we are working on now and going to trial in the new year. Some TDis will have upto 3 map options, from basic spec1, spec1.5 or spec2 and stock map.
