Thanks for being the first to swap the TCU PG. I was looking into this, but of course the dealership was convinced that even with a recode it wouldn't work. Seeing as how they were really accomodating to me when I needed a recode to attempt the controller swap I didn't want to push my luck.
If this does work, I imagine a full idrive retrofit [i]may[i] actually be possible, albeit at some cost. Can't wait to read about your results.
