1, good idea - worth looking in to

2, yes but I have no idea how. The TCU I'm using is actually an A8 FL1 but it's running S8 FL1 software. But, there is no facility to do that with VCDS and the traditional ECU flashing apps like Nefmoto don't appear to be able to do it either. I wonder if a specialist could read the map directly from the board and then flash it back? It used to be possible to get remaps for these TCUs so there's clearly some way to do it but how is a mystery...

I might open it up and see what's on the board
