Injector Data Repository

These are weird. Flow rate table is identical to the LS3 12576341 but the part numbers don't interchange. I wouldn't be surprised if they are internally the same but have some minor fitment differences that make the need for separate part numbers.

The other 3 tables are different, but that could be just GM doing weird stuff in other parts of the cal.

Thanks

Somebody please check my work (the spreadsheet more so than the injector data itself), my eyes are all crossed now and my head hurts I think I need a nap.

GM Gen4 Injectors v1.1.xls

I can easily add more blank sheets if I left out any important part numbers.

Looks good, i appreciate the hard work.

GM Gen4 Injectors v1.1.xls

Caught a typo in one of the injector part numbers, nothing to do with the data, just the tab label was wrong.

This covers:
19421333/12580681 - 29lb, lots of Gen4 trucks
12587269 - 33lb, LY6/L76
12594512 - 36lb, LMG/LC9
12613411 - 38lb, LMG
12576341 - 42lb, LS3/L99/LS7/crate engines
12609749 - 50lb, L92
12613412 - 50lb, L96
12598646 - 52lb, LSA/LS9

@blindsquirrel could I please get the file for 12580426 injectors, 58 psi, non-referenced.

My injectors are actually 25326903 but it appears the 0426 is the new number.
Thanks

[blindsquirrel]

12580426 is already a Gen 3 injector with data in Gen 3 files. 2004-down L59 files will be for 51 PSI referenced/return style, and 2005-up L59 will be 58 PSI returnless.

Injector sizing cross-reference.

[SiriusC1024]

Basic product datasheets for Bosch injectors in Gen 3 and Gen 4 applications.

Examples of usage:
- Consider transient fueling behavior - fuel to wall impact and boil time. 'E' pattern typical for 2 valves per port. Avoid using in LS-based engines. Select 'C' type with similar alpha (α) as factory.
- GTP injector specifications shown in the EV6 file pg 5 column 2. Narrow width 'C' spray pattern ideal for cathedral ports. 'L' long type for LS1 rails. Correct impedance.
- Gamma (γ) angle shown in either file, but specifically EV14, is non-zero on Gen 4 LSA/LS9. Due to mismatch of rec-cathedral adapters, this is a consideration when using LSA blower.
- For 'E' patterns take note that injector orientation must be indexed. Same is true for all non-zero gamma.

My pcm, tune, and original injectors are from a non-flex 04 LM7 (Avalanche) and I got a set of these 6903 flex injectors at a pick and pull. This is swapped into a 69 Camaro w/ returnless & 58 psi. Looks like 05-up L59 data is what I need. I'll get an appropriate tune from the repository. Thanks squirrel!

thanks, didnt realize it had all that bs...

I have Gen3 files with these injectors already converted, both referenced and non-referenced formats:

19421333 - 29lb various Gen4 trucks
12587269 - 33lb LY6, L76
12580426 - 35lb @58, 33lb @51 L59 (old#s 88894361, 89017586)
12594512 - 36lb LMG, LC9
12613411 - 38lb LMG
12576341 - 42lb LS3
12609749 - 50lb L92
12613412 - 51lb L96
12598646 - 52lb LSA, LS9

Problem is two things - posting whole tune files just for the injector data is kinda inefficient, and, posting just the data assumes that people will know to verify they're using the data right - right fuel pressure, right regulator type, etc. Some percentage of people will just find a file/data for a given injector# and use it, not realizing their setup needs something different.

I was given 12613411 injectors in a tbss intake i bought for a 5.3 i swapped into a 92 obs. My ecm is from an 01 Silverado. Could you send me the file i need to make the adjustments for these injectors?
