same part numbers = same parts. any 0411 should be identical to any other 0411 in terms of hardware, software will obviously be dependant on vehicle.
The PCMs being discussed here have a Service Number, Hardware Number, and 4 letter BCC designation. Match all 3 of these, and you have the same part. The early PCMs (512 Kb) are fairly forgiving - the later 1Mb PCMs are not.
Interesting PCM Information:
