Fuel Segment Swap??

[bcar]

I have a 98 C5 that I have upgraded the ECM to an 01. It is my understanding that to get my fuel guage to work properly I need to do a segment swap. Can anyone help?
Thanks

anyone?

Here are the files if it helps anyone or anyone has any suggestions. This is the 99 ECM that I use.

We should be able to swap the segments, just send us the files you want the segment swapped from & to similar to doing a transmission segment swap.

They are posted above or should i email them to support?

One is a 98-non segmented file
the other is a 99-segmented file

not even CLOSE to being compatible segments. As one has one the other does not.

Thanks this info helps, it means I have another problem but I will take any progress I can get. The BCM is compatible with either the 99 or 01 OS. I think I may have a dead or intermittent sender or 2. There have been others do the ECM swap I did but they made some changes using EFI live. My guess was it was a segment swap but apparently it wasn't.
Time to pull the senders and have a look at them. Hopefully I dont have to replace them they are $700

They are probably doing a segment swap from some file, what file I have no idea though.

Would these files be a canidate for a fuel segment swap?
This was originally a V6 truck and now it has a 6.0 from a Van

Try using .bins from an '02 Vette and an '02 Express van.

Are you saying download those from the repository? I sure dont want to license another file, I have already done both of those.

OS 12212156 and the fuel segment from an '02 Express Van
is what Fbody people use when upgrading to the 99+ PCM.
I imagine it would work the same for Ybodies.

This is a popular mod, there should be a sticky somewhere.

My post asking about the truck is a separate issue. This is a 03 truck that came with a V6. Now it has a 6.0 from a express van. The fuel guage kinda works, it is just backwards empty is full and full is empty. I was trying to figure out if you take the fuel segment from the V6 file and and put it in the 6.0 file if it would fix the problem. I am hoping Bill can tell me if they are compatible segments.

Bill? any ideas?

Does HPTuners show anything on the fuel level sensor when you add it to the table of logged parameters? I know it doesn't output to the gauge, but does it have to see input form the sensor? Mine only shows 5V and that's all (98' car with 00' PCM)

anyone?

Today I finished adding the parameters to the "Fuel System Segment" section that you need to setup a 0411 when using it in a hybrid configuration. I don't need to swap in a van segment anymore. The Fuel Segment calibration was used for multiple years and I don't understand why HPT hasn't added the parameters.

[Vetal]

Could you please explain in more details? How did you add them, and what is 0411?

[AJxtcman]

I did it in a hex-editor.
I got it all figured out and then sent the info in to TunerCat to have John add it.
Contact Bill @ HPT to see if he got it from me.

Just checked through my emails, nothing from what I can tell, please resend. I don't think it would be an issue to add in the necessary tables. I'm sure our engineers wouldn't mind adding them rather than having to do a segment swap every time
