Import Injector Data

Hello all. I just ordered new injectors for my 89 S10 that has a 2006 6.0. The engine is stock other than a stage 2 cam and springs. According to data logs it seems I'm running out of injector flow. Truck idles, cruises great, but when I stomp the pedal it acts like it's starving for fuel. Factory injectors are 25 lb. I ordered 50lb injectors from Glenns Auto Performance that were highly recommended. How do I go about importing the data from the new injectors to my current tune? Forgive me, I'm very new to tuning. Thanks

Do you know the part number on the injectors? (the vendor, who did nothing but mark them up by 200% (edit: sorry, more like 300%) and then resell them, isn't all that relevant for finding which data they use)

12613412 is the part#

Pick the tab at the bottom for your injectors. The tables have the same titles as the tables in your file at Engine > Fuel > General > Injector Control. There are two versions of the two tables that differ between regulator types, make sure you know what yours is and then use the version that matches.

(same data, but with colors - highlight then copy only the cells in green: Attachment 136581)

Thanks fellas. I'll give it a shot when they arrive.

Not to be technical here but there is a big difference between it acting like it running out of fuel and it actually running out of fuel.

There is no guess work in this. Hopefully you are using a wideband oxygen sensor to tune the MAF and VE tables so that fueling is correct.

Glad I went to the trouble of making that .xls with all the converted data... every time I post it it never seems to get downloaded. Am I doing a bad job of describing what's in it?

In case that's it, it is a spreadsheet with data for the common Gen 4 GM injectors - 19421333, 12587269, 12594512, 12613411, 12576341,12609749, 12613412, & 12598646 - converted into Gen 3 format. Tables Injector Flow Rate, Min PW, Offset vs Volts vs VAC, & Short Pulse Adder. Includes tables in returnless and referenced return-style formats. Copy and paste.

The person who did my remote tune, saw on the table he set up that the injector fuel flow was maxed out. The tune is in Speed Density.

Oh no!!! $420 https://www.glennsautoperformance.co...fuel-injectors
Ebay new $60 including shipping

I only needed to download your data twice. Once with you original data that worked perfect. Next was your revised data that worked perfecterr....
Have done no less than a dozen of these now without a hitch. Still have another three sets on standby in the toolbox in case he sells out.

$52/ea is $10 more than what you'd pay over the counter at the GM dealership. Jesus.

edit: And a few months ago the dealer price was as low as $35/ea.

I absolutey didn't pay $420. I paid $139.99

Your spreadsheet shows flowrate vs pressure. In my file in HP Tuners it's listed as flowrate vs kpa. Is this the correct measurement to paste your info to?

He's gonna need burped after all this spoon feeding.

Simply didn't see it SiriusC1024. No need for the bullshit comments.

Thank you blindsquirrel for the hard work in creating this spreadsheet! I was lucky to snag some 12594512 flex injectors when I was taking the intake manifold from an LC9 at the junkyard and this will make it so easy for me to import the data into my P59. You are the MAN! I need to buy you a beer or 20.

His injector data and the link to the ebay guy has saved me thousands of $$$ over the last year or so.

I am very new to using HP and have started to build a tune for my new engine set up. I was able to download the injector data and move it over to my tune without a problem. Thank you for having that info available to us, it made that part of the tune very easy!!

But, I gotta ask cause I don't know. What is the difference between the new version and the old version of your data? Cause I moved over the data from the old version I beleive from the thread about "injector repository".

V2.0 is an attempt to idiot proof the file after someone played extremely dumb about it. The guy was one of the types who thinks if they act helpless enough about doing a task then someone else will do it for him. V2.0 and V1.1 have the same data. V1.1 was already pretty obvious with the two offsets, but V2.0 took it up a notch. It just says where the tables are located, differentiates between referenced and non-referenced regulator for IFR, and has pretty colors.

Unfortunately, V2.0 still doesn't have adjustments to Transient>Min Fuel Milligrams.

Thanks!! I am now going to do research on exactly what Transient>Min Fuel Milligrams is and what importance it will play in my injector data..... Seems that one question answered brings up 10 unanswered!!

If you want the quick answer take Min PW divided by 31.12.

Thanks!! I really want to know what stuff is and why I am changing it. I've realized this is not a quick learning process that I'll nail in a weekend. I've actually decided to take a step back, slow down and learn what I'm doing first.... I've got a project in the works and my initial plan was just to build it, and tune it asap. I'm now slowing down that process. I want to know what I'm doing mainly so it's a repeatable process for me. Not just buying a tune and guess work.

Don't be afraid to ask if you'd like help with the data or anything. The example I used was someone who looked at the V1.1 file and asked a question when the answer was already there. It was about unit labels I think. You're taking the right approach, so good luck to you.

Hahaha what's funny is I spent like 20 min trying to find the thread, but this was the one all along lol. Look back at Post #5 and #14.

squirrel we owe ya man.... ya ever in knoxville i;ll buy ya a beer or 4

Broseph do you have an updated link for this spreadsheet? none of the links ive found still work.

thanks

GM Gen4 injectors converted to Gen3 format for P01-P59 PCMs.xls

Thank you brother.
This was a huge help. :pray:
