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.
