It CAN control an IAC, just not the stock IAC currently. However, you could swap it out for a supported unit. It'd just require a little fabrication.

Very little fabrication, you could tap right into the EGR inlet on the upper intake manifold. But that's where I put my IAC. ;)

You know how you have to retard timing on an advanced timing ecu like AF/X if you boost it? Can the MS retard the timing on the af/x if you got a turbo on it hence allowing you to retain the af/x ecu without an MSD or Crane igniton box?

If you have a AFX Ecu ya may as well sell it. The MS replaces and effectively nullifies anything the AFX ecu would do, and that's basically just an ignition timing adjustment.
