stay modded, my friend...
I am no expert but have been looking into this for my own potential swap. What I have learned from others is that the 6.4 pcm does not hook up or at all work with the 05-08 system.Does a 6.4 pcm not work with the 05-08 system? Looking at a power upgrade next year possibly, and going with a 6.4 crate engine seems like a really good option. Just thinking a 6.4 pcm would allow the active runner without a workaround
The workaround previously stated is to use 09-10 5.7 ecm because it works in the Gen 1 system, but has VVT capabilities needed to run the 6.4, but needs something additional to run the active runners that the 5.7 never had. It is my understanding that this 09-10 only works with Nag 1 and running an 8speed would require a lot of changes to accommodate a 6.4 pcm or I believe some shops have devised a workaround for that.
Please, someone that can explain this better than I can, jump in and set me straight!
