I you mean the WoP3 Spitfire, you'll probably have to do it manually. Some of the 2D panels don't open, but do have a function with A2A aircraft, so I found that I needed to fix up the panel.cfg to make it work (that was the Piper J3 Cub).
I have never added it to the WoP3 Spitfire with Accusim. I consider it too complex.
However. I have added it to my WoP2 Spitfire and it works fine in that. In fact it is one of my favorites with Weapon for FSX.
