I have auto tune loaded and manual loaded for comparison but the copy segment option is greyed out. What am I doing wrong?

I don't think LS1A allows segment swap.
Post screenshots.
I just used a 98 tune with manual trans from the Depot. As for screenshot the menu option for 'copy segment' was just greyed out even with cal loaded. Same os of course.
I no longer monitor the forum, please either post your question or create a support ticket.
GMPX, I have a question regarding this if you can take a minute to look it up. I know your busy
Is this something that was never finished?
I noticed when you open an LS1A File it only shows an engine calibration. No other info regarding segments.
Also the H0103 for the gear ratio/ final drive is not populated and is set by EFI live to 0. There for you can not use the calculator when changing gear ratios.
I find it odd that the old 98 Black box PCM has this info populated but not the LS1A PCM's.
I don't expect you to drop everything and fix it, I am just curious why that 1 specific application does not have that table populated as well as why it does not display the other segments.
It is a single segment calibration - in other words, there is only one segment.
The gear ratio (H0103) is NOT stored in the calibration. You can indeed use the Speedo Calculator, you just need to manually enter some values (like the gear ratio).
I find many things GM did odd.
There is nothing to fix - see above comments.
I am Curious as to where the Gear ratio was stored then. It seems like that info would be needed for shift points and so on.
I know it's an old platforum and it's only a 1-2 year thing. It was more of a curiosity thing is all.
I don't have the access or knowledge to look deeper into to the code and how it works. Although if someone would point me in that direction, I would like to learn more about it.
As I stated in my previous post, the Gear Ratio was not stored in the LS1-A (1997-1998) PCMs.
It was stored in the LS1-B PCMS (1999 - 2007), but was only used for Torque calculations, not for Shift Speed nor Speedometer calculations.
The "Speedometer Wizard" was written to populate this value (if available in the calibration) for you - otherwise you simply enter this value manually in the wizard.
