Engine swap 4.6L to 5.4L

I had a 2002 4.6 4wd, swapped the 4.6 to a 5.4. I guess the computer is still thinking it's a 4.6, since the firing order is not the same what do I do to reset the computer so that it fire in the correct order? Or is the order the same? What else would you need to adjust when swapping these two engines? Thanks
