Injector Data Sticky
 

Probably the single biggest issue with a new tune is good injector data. I'll post what I have here.

Data for Siemens 80lbs Injectors. EFILive and HPT data. I'd leave the Fuel to Wall Transient stock. But if you notice any lean or rich conditions on throttle tip in, modify to this. The Min Fuel Mg or Transient Min Mg is a pulsewidth adjustment for idle. Do change this.

The rest are standard issue adjustments. If you have a boost-referenced FPR, just use the IFR Flow at 0 and carry across. Same for the offset table. Use the values in the 0 column/row (depending on EFILive or HPT) and carry across.

Data for the GTP 36lbs Injectors.

Your deka 80 data is tits, i know alot of guys could use that as well.

just got back from dyno using your deka80 data, car drives like stock and made 585/598 on 10# 15* and e85 SBE LS1. just wanted to say thank you for the start off on the right leg.

Would you happen to have the data for GM injectors 17113739 42# ? Thanks in advance.

Nice! Here's the injector data for the Bosch 127#.
Not sure why that link got broken.
At any rate, Ping me and I'll send it to you.

Bump. Anyone?

Haven't seen it. Not even on HPT...

DW injectors provide good data to start with... they have all sizes, i used many of them.

Does anyone have any solid 60# Deka info for HPT? The tall EV1s. Thanks

Is this at 3 or 4 bar?

Well whatever you set your FPR at. In the above, it's set at 4-bar since the baseline fuel pressure is 4-bar. But if you set it lower, you'll have to calculate the IFR.

GM# 12576341 = Data converted from 2006 Z06
GM# 12609749 = Data converted from 2010 Escalade
GM# 12613412 = Data converted from 2010 2500 Silverado

Any questions ask away. To everyone that has asked me for this data over the last several months I'm sorry I didn't get it too you. I've been (actually still am) working overseas.

As with everything on the internet, use this information at your own risk.

Thanks for this.

Btw, I run those Escalade injectors in my car from the L9H 6.2L Flex Fuel motor. They are 42lbs @ 3-bar and 50 @ 4-bar. They work well and are very inexpensive.

It's a great injector to use. I like to use one of these three injectors for NA petrol builds. Cheap, reliable, good data available. I don't like that so many people use injectors with no legitimate data available. Hopefully putting this out there will help.
You're welcome.

any one find any data on this? I need it too

Yeah, I'll post it up tomorrow.

delete. tech doesnt support .xlsx

Data for the 60s.

32# LS2 injectors?

Thank you for this! Question.
1- On (Min PW) what value do I put, I only have the option to put 1 value, do I put 0.5927?
2- I don't see the tab or option on HP- Tuners for (Transient Min Pulsewidth) to put the 0.016 value.
3- If I'm using boost referenced FPR, when you say use the IFR at 0, do you mean that at 0 insert flow of 94.62?


Thank you in advance

Boost referenced, just use the first value in the IFR table and offset table. Since it won't change with kPa...

What OS are you running?

I'm using a 2007 express van ecu ..os 12613248

Eaglegoat, I just found your thread on HP Tuners and this one with the data on these 12609749 injectors and noticed that, in the tune you posted above, you carried the numbers down one row too many in the "offset vs volts vs vac" chart. I'm comparing this to the file name "KP data" that you posted on the HP Tuners forum. Just a heads up for you and anyone else running those injectors. Here is said file:

what do i do to read all the files? do i need hptuners?

That's one of the options. There's a few software packages out there to choose from, the most well known/used are HPTuners and EFIlive.
HPTuners is a little less expensive of the those two and has a wider user base, therefore, you're more likely to get a quick answer to questions you may develop after downloading/viewing your file.

There are a few things, I'm told, you can do with EFIlive that are not available in HPTuners(at least when this was said to me). But that was a feature like enabling a timing change for application of a N2O system while you were driving. Something which the average daily driver probably would not find a need.

You can download the HPTuners software for free to play around with it but you'll need to buy the cable/get the license to actually use it on your car.

thanks, im using efilive. i managed to open the xlsx files by downloading some software, but still cant see the hpt file (deka 60).

Yeah, I'm betting EFILive and HPT are using proprietary file formats. Send me the HPT file and I'll screen shot the Fuel Injector data for you, if that is what you need.

I just bought a set of Deka 80lb and downloaded the injector data but it's incomplete for the efilive tables, has anyone used these with efilive? I got some data from the seller too but also incomplete.

You need to be more specific. You dont change every single injector table when swapping injectors.

I'll have to make a spreadsheet with everything in it tabbed.

EFILive and HPT use the same tables (as they are the GM tables) but how they read and present them is of course different. But if you can pull them off the spreadsheet, you can copy them into the file of your choice.

And you don't have to change everything. Just 4-5 tables.

In fact, most tables you shouldn't have to change. They are control tables set by GM. Messing with them will have you chasing your tail.

Got my genuine SDs today. Going to try this on my vette.

Data is 4 bar, right?

60 lb data legit in 04 Z06
 

Starts and idles great. Going to drive it around tomorrow. https://cimg3.ibsrv.net/gimg/ls1tech...9e3f3dcfae.jpg

Excellent.

It pays to use injectors with known data. Makes all the difference in the world.

And with stock 28s, GTP 36s, LS3 39s, L9H Flex 42s, Ford GT500 47s, ZL1 52s, and the Mototron 60s and 80s... you have a whole spectrum of good injectors with good data.

Above that and I recommend going to Injector Dynamics.

60 SD needs tweaking
 

May have spoke too soon. Getting some strange behavior when driving. Had to decrease the IFR quite a bit. Still tweaking.

However, this is definitely a good start!

The injector data you have for the GM# 12613412 = Data converted from 2010 2500 Silverado is different than the data i seen on hptuners in a excel spreadsheet. I just want to make sure yours is correct since i will be using these injectors in the near future for a friend.

Thanks

Does anyone have data for Bosch 0280155968 Green Giants? Cheers

Did you carry the IFR over from the first cell and hold it steady across all kPa? If boost referenced, you only use the first cell.

Also... your VE may be off. Set the IFR and then tune the VE.

I believe this is what you're looking for. This is old format HPT, but it should open in 3.x.

Sorry, I'm not sure what you mean. Are you asking if I used the first value and copied it over all cells? Like a flat IFR? I had to scale it back and interpolate. First value is 69.3.

VE is spot on. Not sure if it had to do with 58 psi fuel pressure.

I also had to remove a percentage from the offset from 12v on up.

Is the data 100% accurate? If it is, I can change it back and mess with VE. It was just that my VE was perfect with the old 36lb.

I'd always rather have 100% correct injector data than anything else. VE can be retuned. Can someone please confirm that the SD 60 data is 100%?

Thanks heaps for posting this data you have saved hours! Just wondering about your flow rate vs kpa. The numbers seem really high and are past the default limit of 32g/s. I'm running an ls1 p01 ECU if that makes a diff. I would have thought they would be around 12s?

Thanks

can you lost your hpt file? I feel I may need to mod my injector data too seems like it's running rich

The 80lb Deka data is my saviour! Tuning my 383 on e85 with these injectors and data. The car has never driven better or been easier to tune. Cold start with e85 fire up and idled straight away (248/258 112 cam ls1 383)!

I changed the IFR numbers to suite my OS and all is good 👍

Try 69.3 for the first value in your IFR then 75 for the last value, then interpolate.

Anyone have Deka 60's data that the file works?

i used jakes spreadsheets for deka 80's using efi live. Anyone want to take a look at my tune to make sure i did it right. Transient Min Pulsewidth:0.016 and Short Pulse Limit: 2.508 where the 2 i was confused about. Thanks

EFI Tables
 

Seems to be a common occurrence here lately with larger injectors.

PSA -- If you install larger injectors, in addition to the injector data, if you have a "Min Fuel mg" field in your transient fueling, you MUST reduce this value or you will be stuck with rich idle and other driveability issues. Also, recommend setting the transient RPM to a number higher than idle speed. I figured this thread was as good as any to put it out there.

Reduce it by how much? Min INJ PW divided by 31.124308? That would put it at 0.0233

Stock tune shown in HP Tuners has Min Fuel Mg set at 0.045 and my tuner put it at 0.041.
Min RPM is set at 300 rpm and Max TPS is set at 5%, which is same as stock tune.
Only other thing changed in Transient settings was the initial Time Decay Mult vs ECT. For engine coolant temp ranging from -40 to 90, the multiplier was increased anywhere from 0.27 to 0.85 depending on the coolant temp.

I'm using Deachwerks 18U-01-0039-8 and the injector control info was changed based on the data in the attached file.

With those injectors, I would drop it to 0.020. I use .010 for 42 lb injectors as a default. I've seen some really big injectors where people just use zero.

I saw something about Min INJ PW divided by 31.124308
That would put it at 0.0233

I'm not seeing rich idle so I may leave it as is.

yeah, that was the old rule of thumb, but it doesn't always seem to hold true. My 42's had a minimum pulse of 0.8, which is in the 0.025 range, but they did better dropping to 0.010. But if you are not persistently rich, then don't worry about it. my point is that just changing the injector flow rates does not get you where you need to be on big injectors. 38's aren't ll that big, so less of a problem.

Anyone have injector data for Fast 50lb injectors?

jake see below, my 60# are tuned to work great in my set up, the 80 on your spread sheet are way different. what am I missing?

https://cimg5.ibsrv.net/gimg/ls1tech...3bc15b7995.png
this is my siemens dekka 60# in efi live. tuned really well with this rate. trying to go to 80# based off your data and it looks way different. what am i missing?
https://cimg2.ibsrv.net/gimg/ls1tech...1455d69b76.png

You're in grams per second vs pounds per hour... is that the question on why it's so different? You can select the units in either HPT or EFI Live...

https://cimg2.ibsrv.net/gimg/ls1tech...fb31329c57.png
ok so I went in and changed to imperial to copy and paste in then changed back to metric. does this look correct now?

Yeah, that looks better.

Go go gadget imperial!

I dont see the transient wall table in my operating system.
I changed the rest .wont actually be changing injectors for a while until my transmission is in and all good.

Hello, any data for FIC Simmens 72lbs ?
Thanks in advance

By any chance, do you have the data for 2001 C5 LS1?

bosch 02801 55931 (12482704,12533952)

ive looked aroun in hpt but havent found the dead times yet.

Thank you in advance!

A stock tune for the 2001 C5 is available in the HPT Tune Repository. Log into hptuners.com, click on your name for account info and you will see "Tune Repository" on the left side.

Anyone have values for 12561462 for holley term x?

Anyone have data for Bosch 30# injectors? Orange body and says 9186340 on the side.

I'm looking for the Fuel to Wall data for some 365cc FIC (Clinic) injectors. I know it's usually left stock but I would like to see it for comparison if anyone has it. It's not on their website.

Anyone have the data for ID1000's, 4 bar, return style system.

I used the info off their site, but I think I might be missing something as far as minimum pulse width or something. My VE is really really low at near idle and I still can't get it leaned out enough.

Thanks.

Please give us more info:
What is your fuel pressure?
What size engine and cam is this? Turbo or supercharged?
What is your VE near idle?
What is your pulse width at idle?
What symptom and measurement do you have that its too rich at idle?

I'm sure you know this is a huge injector and even with the shortest command pulse width it might still be very rich.
Hopefully someone with similar sized injectors and offer some guidance. :)

Have you tried dropping fuel pressure just to see if that leans it out a bit?
You may need a manifold referenced regulator thats adjustable so at low rpm you can pull fuel.
Cause yea those are BIG :)

GM 12594512 5.3 Flex fuel injectors.

These are 36 lb/hr and were in the TBSS intake I purchased.
Mostly used with the E38, but found a P59 Silverado 5.3 Flex Fuel tune using these.
Tune file attached.
The P59 is nearly identical to the P01, so the data is there. Only extra you have to do is copy the Default Pulse table to the Min Pulse table as the P59 doesn't' have Min Pulse.

Also, a handy way to find vehicle usage for GM injectors is: https://www.gmpartsstore.com/
Enter the part number and it will show which vehicles to go look up in the HPT repository.

Shorty deka V data 80#
 

I'm looking for the shorty style deka 80lb injector data. The data that's posted in the beginning, is that the older long style or the newer shorter deka V data?
