I think you would need a 15 pcm to make it work from what I have read.

I have read that the firing order was changed. There hasnt been much talk about it though.
Camshafts would need to be swapped unless there is a *fix* to change the PCM program for the 11-14's. Everything else besides the cams and possibly the cam phasers should swap over.

The voodoo firing order is different but coyote is the same as 11-14

Think the 15 went back to the 4.6 firing order.
11-14 is 1,5,4,8,6,3,7,2
15 up is 1,3,7,2,6,5,4,8

The cam phasers, chains, gears, and cams are different (mid-lock). The 2015 mustangs PCM through a tuner have both positive and negative adjustment on the cam degree tables. The 2011-2014 do not. That's why it would need a 2015 PCM. A engineer from ford emailed me saying the 2011-2014 intake phasers would not bolt up to the 2015 intake cam. Also you would need to change the intake manifold over to a 2015 unit to utilize the IMRC on the 2015 PCM. So to make along story short, if you got a 2015 motor (or aluminator) you would need to remove the cams and drive assemblies and install the 2011-2014 parts. I personally have a set of 2015 intake cams that within the next couple of months that I will put on the cam profile reader/machine, and compare it to a set of FRRP intake cams to see if the valve lobe opening and closing events are different. My guess is they are.

THE FIRING ORDER DID NOT CHANGE FOR THE 2015 COYOTE

I believe one mustang news site mixed this up and it has been spread since then. I haven't looked at the 2015 ford technical documents, but this is directly from 2011 and 2015 tunes.

2011 coyote


2015 coyote


Both pulled from hp tuners tune repository, the bottom file is definitely a 2015, there are 28 mapped points.
