I think the reason for this is that the EGT probe (and VVT) is crucial to the strategies and models used by this particular code... removing them physically means the code can no longer function as intended...
The feedback from the EGT probe and the function of the VVT in context of the 210/225 maps is built into the execution of the code of these particular maps and without them the program logic is essentially broken...
There are fail safes of course hence the rich fuelling... VVT is controlled (from what I understand) by a system constant SY_NWS:
SY_NWS: camshaft adjustment
= 0: No NWS
= 1: 2-point NWS
= 2: steady NWS
> 2: not defined
I asked this very question on Nef when I was thinking my VVT tensioner was in need of replacing...
VVT delete
There is also this...
Dilema - BAM content inside
...but I fear its not as straight forward as suggested due to most of Nef references being S4/ME7.1 related rather than ME7.5...
