Need some help, I'm trying to make a VZ IPC xdf, and I have the basics sorted.
But now, I'm trying to figure out the extras that no aftermarket or factory calibration software can change manually.

Here is the xdf currently. I have a VZ V6 One tonner RWD bin on the left of the pic, and a VZ cross 6 crewman AWD on the right, The highlighted areas are what I have already mapped, and is in the xdf.

The purple and red text is differences between the two.

Does anyone have any knowledge on what these other addresses may be? Both LE0, both 4L60e, both single window clusters.

Some of the differences will be related to the actual analog needle mapping for the gauge (Compression ratios), since difference face plates have different compression ratios required.

I would agree with that.

The VY AAPL software has the option to calibrate the zero offset for each needle, as well as a calibration map for each gauge (eg. Empty, 1/8, 1/4, 3/8, 1/2 etc.. position for the temperature gauge, and similar for all the other gauges).

I would assume the same applies for VZ (even if it's slightly different, or at a different eeprom position).

Okay, I can work with that. Yeah must be analog, as I already have positions for fuel and temp gauges mapped

i may have missed this somewhere but which chip is the eprom holding this info?
