I use the Hotwire setup in my Hemi Mirada. It works great, and allows for tuning using a Diablosport or Hypertech tuner, so you have a lot of options.
Better clarify the fact that a Diablo Sport tuner will NOT IN ANY WAY do a single thing as far as the Transmission programming is concerned.
The ECM will also NOT IN ANY WAY do anything for transmission programming other than maybe send info the TCM is looking for already. Two entirely different animals where the NAG1 is concerned.
I would call HotWire and ask them very specifically if they can program a NAG1 swap and how they would do it if you don't bring the rear wheel speed sensors over in the swap!
