Netres availability

       Never said the 7747 Would'nt run sans ESC. There are other dependencies
       which hook into the timing tables which have effect upon map and 
fueling.
       It's always more work to get the system to function in it's entirety.
       That being said , some combinations of parts have compatibility 
issues no
       matter what work arounds' are applied . Could be the reason why there's
       so many ECMs with differing CPU code personalities.
