GM ECM injector driver capacity

Thanks for the help, Ken and Bruce.


I think the best and most error-proof course of action is to scrounge up 16
injectors and hook'em up to Bruce's bench.  We can just pulse them dry
(without fuel), if just for a short period of time.

I know I've got at least 12 spare stock GM injectors, so let me see if I can
round up a full set of 16.

Bruce-  if you'd be willing to test the rig, I'd cover the cost of a
computer if we smoked the drivers in yours.  Do you have a 730 or 165
computer for the experiment that can be used on your bench?  I don't have
one-  I'm still in the feasibility stage of this project, which is why I'm
asking the question...  A batch of 16 injectors clattering are really going
to be "whistlin' dixie" on your bench...  You might feel like tap dancing.


Is the consensus to gang the two drivers together (as is stock), and then
run the 16 injectors in parallel from that point to ground?  I'd need to rig
up some wiring for this experiment.

PS-  Still no replies on my Caddy 4.1L v8 DIS for 165/730 ECM soundbite...
I can't believe it!
