Yes, for this Rel.1 as-is, you need to have FSUIPC installed.
And that will solve the issue you mention.
You can download FSUIPC from:
http://www.schiratti.com/dowson.html (download FSUIPC4).
No need to register (buy) it, just install as-is.
FYI: the basic part of FSUIPC (the code that works without registration) is just a software interface used by many FS addons and FSX (SimConnect) and is free.
If you register (buy) it, a lot of other features are enabled; like key/joystick assignments/calibration, and a lot more.
The reason why you can visually move the nacelles with the "/" key (Spoiler Toggle) , is that you have enabled the Spoiler gauge in the panel.cfg.
However, this is intended for using a Spoiler controller AXIS , not just a SpoilerToggle key; which allows you to incrementally set the nacelles.
By default, nacelles control is set to the AileronTrim Left/Right function. See the manual.
If this works now, and you like flying with this aircraft, I suggest you download my Addon4 from the SOH library.
Which adds a lot of features, AND doesn't require FSUIPC anymore. (includes a version of VSTOL interface control made by Maryadi, which operates directly on SimConnect).
By the way: I'm not sure all features of this V22 will work with FSX-SP2; the min. supported FS version (tested with) is FSX-Acceleration and FSX-Steam
But generally, I think it will work with FSX-SP2 too.
