we will expect all power units supplied by the same manufacturer to be:
"i) Identical according to the dossier for each team.
"and, unless a team informs us that they have declined any of the following, they should be:
"ii) Run with identical software and must be capable of being operated in precisely the same way.
"iii) Run with identical specifications of oil and fuel."
Which seems to me will not achieve very much at all. There was an interesting piece released last year in which a an ex Lotus engineer described the goings on at Spa one year when Merc realised that Lotus might be able to take places away from Red Bull. The key point in that piece is that a Merc customer gets Merc engineers in their pit monitoring the PUs and telling you what modes you can use. The engineer didn't say "this is a special mode" or "we have kept ths mode from you", but he did say "use this mode" and suddenly the car started going significantly quicker.
So allowing the team to have identical software doesn't bother the PU suppliers at all, because the customer team won't know what the different modes are or even what modes are available.
