    Question Injector Data Repository

    Like the title said it sure would be nice if there was an injector repository with injector data. Seems every day there is someone looking for or posting data that could easily be looked up in a single repository/pinned spot.

    I was just thinking why we dont have a injector data repository. Here is a couple sets ive used on my own truck. Hopefully more can contribute.

    Found a few more good, known sets of data.

    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.

    If they cant figure out that fuel pressure and regulator type changes flow rate then that is their problem. I normally assume GM data is 58psi but also do research on the injector to make sure the data matches decently.

    Blindsquirrel is 12576341 - 42lb LS3 injector data converted over into GEN3 tables? I have a new set i havent opened yet and FIC (connection) told me since they were OE that they dont send the data with those.

    Hi All, I have an Trailblazer SS with a E67 ECU and want to run 12613412 injectors with are native to the e38 ecu. Does anyone have the interpolated values for Pressure Delta Particularly the "flow-rate vs pressure" and "Offset vs Pressure vs IGNV" ? I think this would be a valuable repository file!

    Early E67 or late E67? Guessing early, since the late E67 has the same axis labels as the L96/E38?

    Yes, I do believe it would be early.

    Since that's pretty uncommon deal I don't have it converted already, if you post your file I can just use that and then repost with it ready for you to flash.

    Taken from 2014 Caprice file:
    Gen3 12639221 Caprice PPV 6.0 58psi non-referenced.hpt

    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.

    for the longest time I've been using the GM 0280158187 injectors with a ball park tune. I used these injectors in my 3.6 Pentastar as they won't max out when I hit 7000rpm. They only hit 75% duty cycle but after using these for just over a year now I switched back to my stock injectors as I have not found proper injector data that will work properly with a Dodge pcm. I agree with having an Injector database as there are so many different injector settings out there and when someone finds a proper injector for there application, it would be great to get the proper injector data to setup the pcm to work accordingly.

    Sorry, I've never even opened a Dodge tune file to see how they work. These things are very manufacturer specific, as different as different languages. Nothing here would apply to non-GM Gen 3 V8s, I don't think.
