Newer Injector in LM7

[rgarza38]

Hello,

I got a 2000 Silverado 5.3vortec. Seller installed an aftermarket intake and larger throttle body. He also says he put injectors from a 2013 2500 6.0, I think thats L93. Even with that, the trucks runs fine on the stock tune.

I starting tuning it, still runs fine. only touched the trans so far, but I want to update the injector data before doing speed density and all that. I am only seeing trim of 11% max, which I would assume it would be alot more, considering the new injectors flow double what the old injectors did. I attached the log file and the tune. Do I just need to change the FlowrateVsKpa table or do I need to adjust other tables like pulsewidth data. And if so where can I find the data. The attachments in the repository dont work for me. Thanks. Log and Tune attached [ATTACH]160074 [/ATTACH]Silverado10+INJDATA.hpt

Start with getting the actual injector part number, not "he said..."

blindsquirl has a excel sheet with all the info you need but you'll need the injector PN first.
Trucks come with all sorts of injectors for even the same year. You need the PN to know for sure.

Thanks for the info Alvin. Straight off the inj, The part# for the Delphi injector is 25323974. Do you a link for blind squirrels sheet or do I need to message him. I will look for it in the mean time.

Maybe he meant newer than 2000 but that part number shows to be a 25# for 2000-2007 GMT 800 trucks/suvs without flex fuel.

So your tune appears to have the correct data for that part number.

Ok. Well that explains how it is running without issue. Thanks. Case closed.
