You should have a Hex Editor Forum
I did this up a few months back on another forum, but it got lost on a server upgrade. I hope can remember everything correctly. jimmyblue may like this
These are the complete fuel segments for 2001 F-Body and a 2001 Express Van. As you can see they are not even close to matching
This is just the section that applies to the Fuel Tank.
Everything after this point will have effect on other functions. You can see that the rest of the segment above has a lot of differences
I outlined the differences in the fuel tank portion
This is the beginning of the segment and when I changed this it had no effect on the fuel gauge operation.
This is the end of the fuel tank portion of the fuel segment. This is the area that controls the fuel gauge
This is what I came up with for a customer. He has a 96 Camaro with a 98 IPC in it, a 5.3L, a custom fuel cell and a 0411. This is what I ended up with
This is the Fuel Sender Input to the PCM for a 98 F-Body's Calibration
This is a 2002 Van Fuel Sender Input to the PCM
This would be the table that would need to be inverted or flipped if you didn't use the Camaro Segment
This is a 2002 F-Body Fuel Sender Input to the PCM.
These are the 2 setting that need to be changed to get the 98 Fuel Gauge to work any of the newer PCM's
2002 Camaro OE
2002 Camaro with Van Settings
I will tell you that this is not the 98 Fuel Gauge Hz setting I use
Dave I hope you have time to look this over. I hope it sheds some light on Hex Editing.
I can find the VIN number and pcm serial number in hex!
But yeah,that's about it.
What would be the result if you replaced the 12 digit serial number with all zero's or all one's in your experience?Anything negative?
Why?
If something about hex, or editing in hex comes up, it's because it's relevant to a particular subject that already has an existing forum.
Even general Hex editing already has a forum, "Other EFI systems and related topics", Alternatively if it's more of a tutorial, or "how-to" as it were, there is the "Fuel Injection Writeups Articles and How to New and Old" forum as well.
The man who says something is impossible, is usually interrupted by the man doing it.
