[Gmecm] ECM test bench

[Bill - Comcast]

I started a twiki for the ECM Workbench. It's called ECMWorkbench :-)
and it's under ECMInfo.
http://www.diy-efi.org/twiki/bin/view.pl/Gmecm/ECMWorkbench
There's a pic of my 1227749 bench in it.

If anyone wants to add to it just click the 'edit' button at the bottom 
of the page.

Through holes for the injectors & stuff would be fine. If they're laid
out for a terminal block you'd have the option of using a terminal or
just soldering the leads into the board. DB connector to the ECM harness
would be OK.
