ok, I searched, but it's going to take too long to find just for a simple question.

When do the secondary injectors come on-line?

don't shoot, but I've heard conflicting stories.

 

taken from rynberg on another thread


The secondaries come online only above 2750 rpm whenever the primary injector duty cycle exceeds a certain percentage. I don't know the percentage, however, given how other things are setup, I would guess when the duty cycle exceeds 50% on the primaries. So the boost pressure that this occurs at will vary by rpm..



hope that helps

 

thank you!! I just want to becareful on my drive back home, so I can keep my milage as low as I can..... appreiciate it!
