Does anyone have a MAP of the VE table on how it correlates to different Fuel Trim Cells?

They both index by MAP and RPM, but the FTC
boundaries vary by vehicle and year. Several
different FTC maps are to be found in a thread
on the EFILive forum. You can program the FTC
boundaries to suit yourself too (I changed mine,
the late F-body boundaries are just stupid).

What did you change them too. Can you post a screeny from efilive so we can see.

Anyone have a map for a 2002 Z06?

Is this what you're talking about? I also changed mine to match this cause they were messed up.

My RPM boundaries: 1000, 2000, 4000RPM (My
converter winds up past 4000RPM if I'm on it
so WOT is always above 4000 except right off
the line; idle is always below 1000; almost all
normal driving is between 1000-4000 and that
space is "octave divided". Just my personal
philosophy, that.

My MAP boundaries are 40, 60, 80 because
I idle about 35. Just trying to minimize the
area "wasted" on things that don't matter
(idle) and things that closed loop can't help
(WOT), and maximize the number of cells
dividing up the "worthwhile" closed loop
operating space.

My stock boundaries had like 800rpm, 1200, 6502, and 6503 or something stupid like that. I thought that's what you were talking about.

That's where mine were too. That's just
plain dumb, making 3 cells cover the whole
non-idle RPM x MAP range pretty much.
