Ok, there are about 12 "updates" for both the .6 valvebodys and ETC.6 control units. They have to match or it simply wont work right.
$4500 really isnt too bad as the reman unit lists for a tic over 3K and the .6 control unit is around $700 by itself. Labor is generally around 6 hours to replace. Keep in mind the reans dont come with converters either.
