Installing LS3 injectors in 2001 F-Body, need LS3 data

[Billiumss]

I'm installing a built LS3 into my 2001 Camaro SS M6 and I will be using LS3 injectors.

Does anyone have the LS3 injector data to be used in an F-body application? I looked at a 2010 Camaro file and it's not the same as the older stuff.

Any help is appreciated!

Some one posted this once, I can't recall who it was.

You should feel lucky, I had to search for months, and bug some really intelligent people, who did a lot of math work to get that data. You got it in under 30 minutes!

I put it up on my website so it can be someplace permanently.

Still no "Advanced LS1 GEN III Tuning Guide" yet ?

Sorry, nothing yet. I will be off work for two weeks for surgery, maybe that will give me time to do some more work on it.

That spreadsheet isn't quite accurate. I'll refit all the data from a 2010 Camaro later... Too lazy to write the Excel sheet to do it right now.

Thanks, I will repost the updated file on my site when you finish it.

Thanks guys! Very much apreaciated!!!

Hey there,

I am the creator of that sheet. I used it to put LS7 injectors in my LS1 with some custom adapters I made to acccomodate the height difference. So, the actual data in the sheet isn't from an LS3, but rather an LS3 "style" injector. The math and conversions should be correct, but the actual values may be different on the flow rate table due to the values being from an LS7 - 42 lb/hr injector. All it would take to make it correct is to find a stock LS3 .bin file with the injector data in it and copy it into the sheet. That's what the sheet was intended for anyways.

If there are any other errors in the sheet, please let me know. I'll be more than happy to update it and correct it, but I couldn't find anything off when I originally made it.

For the record, my truck that has the LS1 with the LS7 injectors runs and idle's like a champ from using this sheet.

Thanks,

Cody B.

I'm sure it runs fine, but being the picky perfectionist that I am, there is a better method to translate the data instead of interpolation into the LS1 format.



Edit: Attached is an LS1 file with all the injector data entered in. This injector data was pulled from an LS7 file... yes, the 2010 Camaros have different numbers, but they are the same injectors.

Thanks so much!!!! So I only need the 3 tables that were changed then?

The short pulse adder is WAY different than my stock 2001 file.

What about MIN Injector Pulse and Default Injector Pulse? They can stay stock?

Again thanks for everything!!!

[DSteck]

Short pulse adder is a characteristic of the injector itself... it has nothing to do with the car.

Yes, default and minimum pulse are fine.

So i just bought some 42lb from an ls3, what i need to do is add 16.8 to my injector flow rate vs kpa vac, that gave me 42.2. Is how the tuning school show me (25.2-42=16.8). then copy the ls3 injector data to my offset vs volts vs vac.

correct me if im wrong...

That is a dead wrong way to do it.

Just take the data from the file I posted.

[02Ls1]

Ok. do i copy the the flow rate and the offset vs volts tables or theres another table i have to copy?

[Tongboy]

I know this is an old thread, but when you change injector data rom LS1 to LS3, what will that do to the tune? Will it mess with the VE table at all? Make it go lean or rich?

VE is unchanged, the computer will use the different injector data to properly meter the fuel to fuel appropriately for the VE table and all the other parameters that come into play.

as long as you aren't leaning out or something in your VE table up top changing injectors should not require any further tuning other than the injector data

This is an old thread (to mimic what a previous poster said and now it's even older) but the post I quoted concerns me. I was considering attending the tuning school. But the quoted post makes it seem like they are taking shortcuts.

[oakley6575]

If i'm reading this correctly, are we trying to get the data from the ls3 injectors at 58 psi?

[Exidous]

The LS3 injectors are rated at 58psi. The issue is that the tables from an LS3/7 don't carry over to the LS1 OS.
