Use the manual mode D range for the paddleshift.
Where it compares the looked up value with the calcuted value jump out and run your own code that says
if not in manual mode jump back to normal compare
if not in d range jump back to normal compare
if gear 4 jump past next line
if the input for the upshift paddle is active set looked up value to compare value for upshift
if gear 1 jump past next line
if the input for downshift paddle is active set looked up value to compare value for downshift
jump back to normal compare
It looks good to me in theory.

I was thinking to adapt Ryan's paddleshift code because it is tested and working rather than try to write something new. For example, he has safety checks in place so that you can't change down if the mph is too high and will overrev the engine.

I really want to get back to playing with the TCU. But I've been distracted by another project. I'm busy helping a guy to find the parameter addresses for his Impreza EJ15 ECU. It's a Hitachi unit and the code is quite nasty.
