To answer questions regarding cam indexing. GCR clearly states in the rules, you can re-key or index cam shaft to compensate for milling head, its legal.
If by compensate, you mean bring back to factory specs, then you are correct.

Cars with adjustable cam gears, like the E36, MUST be set at factory specs.

Reread the ECU rule, then read the threads on Motec on this site. You're way off on the computer rule.
