Fact #1: Injector flow varies with manifold pressure or vacuum, example from a 97 Corvette:

Notice the flow rates get bigger as vacuum increases, meaning the injector pulse width is going to decrease (larger injector constant = smaller ...

FPR (1:1 ratio) is to combat the pressure against the injector. While MS can compensate to a point -- you would need to jack up fuel psi to you expected boost to get the rated injector flow.

Tommy,

MS manual states banks will fire on "injection events"

My question is...what exactly defines an injection event?

Engine Code:L67 3800 SII (97-03) is a very potent motor. I've made 450whp, 540bhp on 93 octane with turbo setup. Stock bottom ends are very strong, they are very sensitive to detonation, so don't be shy when it comes to high octane (110+) and somewhat rich air fuel ratios (11.0-11.5:1 - .74 to .78 ...

Sweet paint picture of what's going on in my brain:

Hi Folks,

Have v6 with firing order 1-6-5-4-3-2

Would it be correct for 2 pulses per cycle in alternating fashion (every 360 * crank rotation--one bank is fired?) for bank 1 to consist of 1-6-5, and bank 2: 4-3-2?

I see them 120 degrees apart (even fire), 1-6-5 are the first 360 degrees crank ...
