Sorry dumb question.
Which load table? Volumetric Efficiency, Closed Loop Max Load, Max operating Load?

I've only ever needed to adjust the Maf Scale or Injector Size to manipulate the idle.

Yeah i dunno. I just want to mess with idle afrs.
I played with an adaptronic recently and it was handy as it had its own idle table. Gone back to stock ecu and derp.

Found it. In the afr tables 1 2 or 3, at the desired rpm it is approx load 0.18 to 0.25. Wanted to see how a change in afr impacts bridgeport idle. Either it needs to be pig rich where it smokes and idles bad with aft of about 8, or slightly lean at about 15-16. The latter gave better braps. Not as good as the braps on adaptronic though. This stock ecu is too smart!
