Go to dakota durango forum under the 5.7 hemi section.
Look for FrenicX post.
He did a 2005 4.7 to 5.7 swap.
Used the 4.7 ecm with a tune.
HP tuners has the ability to tune said ecms from 04 and up.
If you use the stock ecm you cam keep all the bells and Whissels with no check engine light.

Thanks, but mines a 3.7 V6
That's supported as well!
My understanding is that the ECM are all the same, just the programs is different that go into it.
I think you can reprogram the 6 ECM to an 8 and away you go.
If not get a use 4.7 ECM an go from there.
Once again I have not done this but will be in the near future.
