Somewhat confused, I only see 2 tables for both AFR base and acceleration enrichment, is something wrong? My car is a Series I 6 port 6 spd manual, however, the ECU is swapped from another car, to the best of my knowledge also a 6 port 6 spd. I do see injector scaling 1, 2 and 3 for all 6 injectors as well as max loads 1, 2 and 3 in absolute limits if that means anything.

Different years had different number of AFR tables.

And no, it does not have anything to do with gearing. they are used for different driving condition depending on the cars logic. best to keep all of them Copy/Pasta

FIX: my car was running off the table, i.e. the fuel table went to 9,000 rpms but i was revving to 9,300. i had to rescale the fuel table axes to allow myself to enter a a value for the highest rev range. that allowed me to lean out the 9.000-9,300 range.

How have you done that?
Just recalculate all values to a higher number in all cells to get them higher at all RPM spec?

I mean - there is no way of changing the preset VersaTuner column values, or is it possible?

In other words - you still type value to that 9000RPM column, but the value you type in is recalculated as it should be at 9300RPM, right?
