This is a product that the Durango/Dakota/Jeep guys would love to have. 42/44/46RE's
It would be so nice to use a different ECM like a Megasquirt without having to piggyback on the stock JTEC and hoping you don't do something to kick it into limp mode. Or even ditch the EFI all together and use a carb if you want.
I searched the megashift forum and never found where anyone had really made any progress adapting it to a Mopar trans.
