Re: Mods to '85 GM TPI ECM

Check out Ludis's site.  http://www.cruzers.com/~ludis/
Print out the P4 section and it gives you  a lot of good info on where to
find certain ecm's.
730's don't use maf's they use map and are speed density so no relay is
needed.
GMe is "GM Editor" and Terry Kelley writes it.  I really like it.  It allows
some really neat stuff to be done.
Diacom is a diagnostic tool, it uses an interface from a laptop computer and
allows data to be recorded so you can tune your vehicle, other wise it's
just a guess.

Mike Rolica has been great about sharing onfo on the 165 to 730 swap.
I am planning on starting the change on mine soon.  (When my wife lets me!)
