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.
