2007 E38 4.8 Truck, need to put injector data for a 52# LSA into it, but a bunch of non-editable scaling is different.
Attachment 146158
@blindsquirrel all of the fuel tables are correct including the transient tab or just the fuel general tab. Just want to make sure as I dont want to hurt my new 416 set up just want to get it running good enough to drive to tuner to be put on Dyno and tuned.Quote:

Thanks for clarifying, I knew spark, idle, airflow, iac, and ve for sure needed to be tweaked which I have adjusted for I was just unsure about the transient. Some people zero out some of those tables. Just need the starting base so it runs not stumbling on its face first start up. Thanks for clarifying and submitting the data:) Stay humble!Quote:

Yes but whatever data was provided you could just as easily got to by making adjustments based on how it behaved. i.e., it's just tuning, it's not hard specs that shouldn't be fiddled with like the other injector tables.
Hi I've got a cammed ve ss manual I've been having problems with tuning at several shops but I've just realised someone has put ls3 injectors in it are ls3 injector data why different to l98 injectors?
Your other posts have been about a Gen 4, are you sure you want to be looking at data that's been converted over to Gen 3 format?Quote:

This is the information I had found way back when for the Deka 80 injectors.. it may not be of any help, but I figured I would share it.
Specifications:
Static Flow Rate: 80lb/hr = 875
cc/[email protected] PSI
Dynamic Flow Rate : 18.6 mg/pulse 2.5ms PW, 20 ms
Period
Coil Resistance: 12 Ohms (This high-impedance injector will work with all factory ECM/PCM injector drivers)
Connector: USCAR or EV6
Series: DEKA 4 (DEKA IV)
O-Ring Type: Viton
Cross References:
Siemens FIl14991 or 109-991 (
109991)
That's not 'injector data' like what you need to set up a GM PCM or ECM. Check out literally any of the spreadsheets posted in this thread for an example of what 'injector data' means.Quote:

Use any stock tune file for a transfer of data.
Any stock 2003 Silverado LM7/LQ4 file if referenced/return style, or any stock 2005 Silverado LM7/LQ4 file if non-referenced/returnless. That's an old number but it crosses to 25320287/17113698/FJ10062/FJ315, the default generic injector used in all over in the non-flex trucks from 2001 thru 2007 (not every single one, but lots and lots). They are only 24lbs, make sure they are big enough for your plans before potentially wasting time on them..Quote:

Attn: Blind Squirrel
Do you have any data formulated for running LS1 injectors 12561462 in a 2009 Trailblazer E67 12630465? I can do it properly, manually but it's a time suck. I have a lot to do before leaving on vacation and just can't really afford the time. Happy to pay. [email protected] if you need to send anything over.
There isn't enough data in the Gen 3 files to fully populate the whole tables in the Gen 4 files, the tables cover a much much wider range of pressures. Gen 3 only goes from 0 (normal atmo) to 80 (20 kPa MAP, or max vacuum) kPa; the Flow Rate table isn't that difficult as flow rate is near enough to linear and can be extrapolated, but the great big Offset table in the Gen 4 would be left mostly blank either side of the 408-488 kPa Delta window. If you're exclusively naturally aspirated, and running 58psi rail, and no FPCM so the rail pressure is always 58 no matter what, that's the only range that your combo can ever utilize, but it's still not the whole dataset.
If you're running a referenced regulator it can also work without having the full range, as all the columns are the same all the way across and only need one column from the source data.
In short, maybe, but only depending on how you are using them.
Yes it's NA and I know about the tiny part of the IFR that will be used and the tiny square of the offset table that's used as well. I just began removing the .5 volt rows and thought "I bet someone has already done this and could get me rolling quickly".
Thanks
quick question
25326903 interchanges with 12580426 Correct?
psiconversion.com thinks soQuote:

The 903 injector is a Denso and the 426 is a Delco. Same injector same data as far as I knowQuote:

Going to be using a manual OS for this but need the data from the bone stock motor.

No, not from any stock file anyway. They were '99-'00 truck only and didn't carry over into the returnless era.Quote:

(sample returnless data, truncated to show only 0 - 0.5ms range)
Attachment 149030
It is bone stock and going to stay that way. In fact it will be a little detuned. Going in a DeLorean and don't want to break the transaxle even though it has the billet input shaft.
Yeahbut making it idle right and predictably come down to idle and all the rest of the fiddly stuff has nothing to do with how much power it makes or whether it needs billet unobtanium whatzits. The 'important' injector data is only in play at very small PWs.
Why not put in a set of 25lb injectors from a 01-06? Its not like they arent in every junk yard.

One glaring clue that it's a bunch of horseshit is right at the top of the page:
12613412 was never used in any 6.2L RPO. 12609749 was, but that's a different injector with different characteristics, despite being a similar flow rate, and for the longest time lots of people conflated 12613412 (L96) & 12609749 (L92/L94) and used the same data for either.Quote:
