So far tuner pro has worked for everything I needed except setting up the fuel gauge. I swapped a LQ4 6.0l into a 99 suburban and trying to get the fuel gauge to work. I know that it runs through the computer but so far I cant use tuner pro to change the tank size or set up a output for the gauge. Is tuner pro incapable of doing this or does a depend on a certain XDF file? Thanks.
Does you gauge even work?
It is possible the motor that runs the gauge has failed. May need to get a scan tool that allows testing of the gauge sweep. Had this with a neighbors swap. He swore up and down the gauge worked before the swap. Pulled the cluster and put it on the bench, no worky! Replaced the lights and motors and reinstalled, it all works now without messing with the tune.
Also there are some sending units that work backwards and this will be a wiring issue. It is documented on the GMT400 forum!
Sheesh, I haven't been involved with too much dash stuff except for swaps that have worked fine. I want to get more involved with this especially since it seems to be a future effort.
It seems to me we should start a thread that can ultimately lead to a sticky containing the .bins of the dashes. :thumbsup:

Sadly I cannot remember the name of the program and cannot find where I saved it on my laptop.
Friday evening after a rough week at work, working on deflating with a Shiner Bock.
Maybe re-engage brain tomorrow.
Post the bin you are using and I'll see what I can do.Quote:

Just to verify your 99 Suburban was originally a Black Box 4 connector PCM? And it looks like for some reason it is a 04 OS that you put a 03 Sierra VIN in it? What fuel system? Return or returnless? That 04 OS is set up for a returnless fuel system with the regulator in the tank.
Yes my 99 suburban had the black box with 4 connectors. I used 2004 LQ4 DBW and had to change the OS to 7603 because it had the 9405 OS. But the fuel system is a return style which would probably explain my stumbling problem.

The table may appear inverted, however it is the amount of Kpa VACUUM at the tip of the injector.
Do NOT compare to the actual Kpa in the intake manifold.

The fuel gauge tables in a 99 Black Box PCM that are going to control a 99 cluster are nowhere near compatible or transferable from a 04 P59 OS. Tunerpro doesn't even show all the 04 tables either.
And there are a few other injector tables that are different between return and return less fuel systems besides IFR.
This is the best I can do showing you the differences between a 99 and 04 OS Fuel Gauge calibrations. I used excel files for a couple of the tables because the tables were too big for screen shots. I'm only showing the tables that have common names between the 99 and 04 OS.
This is what Im trying to accomplish in the photo. Its not perfect but guys adjust the fuel table to get it close. But a output for the gauge needs to be set because the factory 04 gauge worked through the BCM. I might just buy the fuel gauge module and give up on this. I have been trying to find a fuel segment for a return style for the last 2 hours. I might just have to scrap turner pro and get HP tuners at this point.
Are you wanting a 04 Van fuel system segment (segment 6) swapped into your file? If so I can do that. And I can also input the return style injector data. That is easy.
That would be amazing. I would need the fuel segment from a 2002 5.7l van and the fuel gauge output enabled. I believe it sends it to pin 54. I also need the tank size changed to 42 gallons. I would be much appreciated.
Here are a couple bins. One is your file with just the return fuel injector data, and the other is same with 04 Van fuel system segment which has the tank and gauge data in it swapped. Also it looks like your base file is a pretty much stock 04 6.0L calibration which is kind of a turd in its stock form.
I saw your rely after I posted. You cannot swap a 02 segment into a 04 OS. OS have to match between the 2 files you are swapping between. That is why I used a 04 Van segment. If it has to be from a 02 Van then you would have to switch everything over to 02 blue red PCM.
Thank you fine sir. Tuning is definitely in the future. Just trying to get the truck on the road and bugs worked out. But the original 04 truck did seem like a dog.
Here is an updated bin with the tank size set to 42 gal. I made the first file before you said you needed that. But again it is a 04 Van segment so I don't know if it will help with your issue.
