I doubt that they expose the difference between an IFL and a GP (General Purpose) engine as an IFL, basically, is a GP engine loaded with different microcode (to prevent the engine from being able to run z/OS). It is a full speed engine where a GP engine can be slowed down, via microcode, to reduce software licensing costs in a z/OS environment.

I don't know if that means it's information IBM does not want to make publicly available, or if the IBM developers just never bothered to expose it. It might be worth asking your IBM rep. about it.
