Peak and Holds in a '165

[Bruce Plecan]

The highest capacity injector driver ecm that gm makes that I know of is the
749
that will run 4 P+H injectors (two final drivers to do that).   So if you
might be able to take the drivers out of one of those, but then you run into
heat sinking problems.  I think you might look at some of the 332 archives
for building an external driver board.

| The ECM is only gonna supply 4A peak for a single P&H injector.
| Ok, is there anything I can upgrade in the ECM that will supply this kind
of
