    Honda uses a map sensor (MAP) and throttle position sensor (TPS) on
    their engines. That would really simplify your system. The idle speed
    control (ISC) on the bottom could be taken off if not needed.

   Could you possibly provide a part number or year/model info for the
   pictured throttle body?

   I don't need a TPS for speed density. Just manifold pressure and temperature. The TPS just tells the computer, hey we are at full throttle right now, while the manifold pressure slowly catches up to reflect the full power change. Gives a chance for the computer to start to add fuel sooner.
