hello all
I just got my truck out of the garage and need some advice. I am using
a 749 sunbird ecm to fire 2 injectors in my GM TBI.
first...the GM tbi uses the P&H style injectors corrcet? I am only
driving two(of course)injectors-- one from each injector output. Am I
overheating or destroying anything?
second...i am going to use two tbi's to feed my roots blower so i need
to drive 4 total--can i just wire 2 injectors to each of the ecm's
drivers? I have the parts to build an injector driver board sitting on
my bench will i need this? I read a few places where the 749 can drive
4 P&H injectors stock..is this for real?
third...what do the injector jumpers on the 749 do for me? it shows in
the 749 pinout to have them connected together. I currently have them
connected togther(the proper wires together of course) and the whole
thing seems to run just fine.
thank you for your time
