GM ECM injector driver capacity

[Ken Kelly]

Brock,
	From all I have seen about the ECM driver circuit, I would
agree that a second driver for the additional injectors
would be a good idea. I would probably try to drive it from
the ECM injector output. I would leave the first injectors
on the stock driver, and put the second injectors on the new
driver. I would delay the opening of the second injector
slightly, but close it in sync with the first injector. 	If
you did this idle and cruise would only use a single
injector, so you would get good fuel control & economy for
normal driving. The second injectors would come in as soon
as the ECM called for longer solenoid dwell times. It would
put a kink in the fuel curve, but that can be compensated
for in the ECM calibration.
