I'm confused what you mean by
I have the AOA Sport module in my wing, but the display on my AF3400EE non-s is for the AOA Pro
We only have one style of AOA pressure ports for all of our AOA systems (AOA PRO, Sport, EFIS). The only difference is where those 1/8" hoses from the wing ports go. They can either go into the Sport CPU, Pro CPU, or into an EFIS. If you are getting the EFIS, you'd plumb the AOA hoses into it. You are correct in that you can't have a separate display for the AOA other than the EFIS screen.
