It isn't real clear to me what you meant (since last I looked all their rows in closed loop are TPS not just the top one), so I will have to guess.
I have no idea what TXS has in mind on achieving the conversion - but I am positive it will not use TPS as the load - it will have to use MAP to achieve the conversion and it will be achieved the same way it could be achieved now with Xede.
I am merely saying that it can already be done with a very flexible tool (Xede) that most don't even realize how useful and powerful a piggyback it is. And as always am seeking input on my thoughts.
Edit: looked again I see open loop fuel is a map load - so why is this a future ability instead of a current one, just move the map to the entire range.
