This is why you see reflashes like the AccessPort using a common ECU revision where possible. For example, all 02-03 cars end up getting reflashed with the same image, all 04 gets the same, all 05 gets the same, all 06 MT gets the same and all 06 AT gets the same.
From a software and map maintenance standpoint the fewer maps you have to keep track of, the better.
