Does anyone have the injector data for the ls9 injectors that I can use in the ls1 computer. The data used in the ZR1 is referenced to pressure and not vacuum. I'm not that smart, mostly a cut and past kind of guy.

It's a 05 gto tvs 1900 kit going on a ls1 in a 3rd gen swap.

If anyone can help that would be really appreciated.

 

Gave you a phone call and emailed you what you needed.

I'll leave this here for anyone else who needs it.

 

I've the data loaded in my tune if you want to cut & paste, let me know.

 

mike13,

is your FPR manifold referenced...?

 

No but I think I got the info needed.

 

If the FPR is not referenced off the intake manifold won't fuel pressure rise causing a change in injector flow rate?

 

FPR manifold referenced: rail pressure changes with MAP (so IFR table is required to be flat constant regardless of MAP).

FPR unreferenced: rail pressure stays contant (so IFR table is required to have squareroot-MAP relationship).

 

Ok so since my FPR is referenced to the intake and I am running SD 60lb shortys at 3 bar I should be running 56lb's across the board without regard to kpa increase? 56lb's is the value at 0 vac on the Banish CD I have and then using the Bernoulli principle to convert it to 3 bar from 4.

 

Yes, correct, for manifold referenced FPR, use the 0 vac value in all cells all across...

did you measure rail pressure with reference hose disconnected from FPR (did you measure 4 bar (58 psi))...?

then wouldn't your IFR at 0 vac be calculated like this: 56 lb/min * sqrt(4/3)...?

 

No I haven't made it that far yet. Haven't started the car with all the new stuff I put on it. Just trying to nail down the base tune so I can start it before taking it to Vengeance.

I appreciate your help, thank you!

 

What injector adapter did you use to make the zr1 work with the ls1? I'm having trouble finding out, Could you pm me thanks
