Fuel iInjector Question for LA3 Computer

[KenneBell]

Using an LA3, do all injectors fire at once?

On the 88 Turbocoupe do all 4 injectors fire at the same time?

 

[mr_woodster]

no, i believe they are sequential (2 banks).

That would be batch fire. Sequential would fire each one individually. I've been told that they are in fact batch fire.

 

[mr_woodster]

err, thats what i ment. Mixed up on terms, but the banks was in my mind

I knew what you meant, just clarifying for anyone who didn't.

What I do not know is what pairs fire together.

On a side note, I was listening to my SVO running with the hood up and noticed the injector clicks sounded aweful far apart. Its only now I made the connection that the batch fire is partly to blame. (I was used to hearing a sequential-fire 5.0 HO)

They do all fire at once, though there are two injector drivers in the ecu...

Say what? They all fire every 180 degrees?
