The fuel injection system on the 2.8L is non-sequential, correct? Is there a way to convert it to sequential?

 

as far a s i know theres no real advantage to seqential.and your ecm is batch fire.

 

They basically are sequential- firing order on a 60*V6 is 1-2-3-4-5-6

Right bank 1-3-5 Front to rear
Left bank: 2-4-6 Front to rear

 

I do not believe the fuel injection is of sequential style... I think the right bank fires, then the left. That's about it. I'll have to look this one up.

 

Batch fire, AFAIK... Also, no real advantage of batch fire vs SFI - unless you've got variable valve timing to boot.

 

There is an advantage to SFI, it allows for better A/F control, allowing better milage, emissions, and power. Why do you think the LS1/LT1 motors are SFI? Not because GM thought it would be fun. It also allows the computer to sense bad injectors and crap like that, that way it can narrow problems down to a single cylinder.

Granted the difference isn't worth it to us, nor will it make a difference on our cars, but that's the reasons makers choose to use it, I'm sure.

And just to make sure we know, it's batch fire. That's why you can look at the wires on the injectors and the left side all have the same patterns, and the right side all has the same patterns. Also, the wiring diagrams all show the the injectors for the two sides are wired in parallel.
