Need LS3 Injector Information

[1320king]

So my setup is as follows: LQ9 short block (cast iron LS2 pretty much), with a full LS3 top end (intake, injectors, heads, etc.).
I already loaded my ECU with the LS2 base calibration, and made sure all my sensors & stuff are setup properly, but I'm not
sure on what to set the LS3 injectors too. Like the dead time & stuff. Wondering if somebody could help me out with this.

It's LSx engine related...isn't that information available on the internet?

I thought maybe there was a Holley file or something that I could have just loaded. Danny, do you happen to have a screen shot of an LS3 map? I can't seem to find a base calibration LS3 HP EFI map to save my life.

No, I don't...sorry.
Just need to program the correct information into the Engine Parameters, Ignition Parameters, Sensors, Idle & Spark ICFs.

Remember, the base calibration you start with, must correspond to the MAP sensor you're using:
For example, you can't use a naturally aspirated base calibration for a forced induction engine.
This is because the 2,3,5 bar MAP sensor selection only changes the kPa load Y-axis, but not the Base Fuel Table lb/hr
values (creating an excessively lean map) or the Base Timing Table degree values (excessively advanced timing map).
You must choose a 2,3,5 bar base calibration or reconfigure your existing Global Folder's Fuel & Timing Tables accordingly.

Hey, just looked at an Excel spreadsheet, and I'm not sure how to interpret that into the Holley HP EFI? I'm not sure what to set the Injector Off Time to?

[Danny Cabral]

I'm not sure what to set the Injector Off Time to?

I would contact Holley Tech, and see if they have the Injector Off Time curve for GM LS3 fuel injectors.
I don't want to risk giving you the wrong injector data based on someone's Excel spreadsheet off the internet.

UPDATE: Open the "Help" Contents (top Toolbar), and click on "Injector Flow Data".
The Injector Off Time Curves are listed for most GM LSx part number fuel injectors.
