The 730 is a three plug ecm, the 165 as you know is a 2.  You can trim a 
second large connector to work.  Or in the archives (sorry) is GMPP John 
Flagg's Co where you can buy the connectors pins etc (connector+header).
730 AIR, has a few more wires, and some switches to flip to "see" the 165 
VSS which have been documented (archives). 
  If I had you current memcal, I could copy the timing off of it, and te use 
that on the 730. But, would  be time consuming for the mail etc..
  Would also need a 730 memcal.
  730's used in lots of FWDer's, amd any v-8 memcal would be fine for what 
your doing.

  The h255 is just a max value, not expressly grams/sec..  Could as easy be
510.
