I picked up a set of 12613412 injectors and would like to take a look at the stock tune.
I didnt see one in the depot.

Thanks

Looking for the same but I need gen3 tune data for them. By chance do you know the engine code?

I *think* L96

If it's L96 then see this post by Wipped383 in another thread: Correct-IFR-tables-for-LS3-LS7-injectors-in-Gen-III~post#132 (https://forum.efilive.com/showthread.php?11498-Correct-IFR-tables-for-LS3-LS7-injectors-in-Gen-III&p=234526&viewfull=1#post234526)

Thanks @joecar!
One last question. since the IFR is done via delta kpa. If the injectors are rated at 3bar but will be running at 4bar, do I need to scale the table by 1.1614 [sqrt(58/43)] or will the delta cover this?

You will still need to scale the injectors... scale by sqrt(58.0/43.5) = 1.1547 (since 3 bar is 43.5 psi).



Delta kPa refers to the pressure difference between top of injector (at rail pressure) and bottom of injector (at manifold pressure)...

if FPR is 4-bar (58 psi, 400 kPa) the absolute rail pressure is 500 kPa;

MAP (manifold absolute pressure) ranges from 30 kPa (closed throttle decel) to 100 kPa (WOT);

so delta kPa ranges from 400 kPa (WOT) to 470 kPa (closed throttle decel).
