Agreement reached on engine mapping rule, but will it change the order again?

In the background of today's exciting Grand Prix at Silverstone, the teams agreed to a plan for the rest of the season on the off throttle blown diffuser issue.

After a meeting this morning at which Sauber refused to sign an agreement to revert to the rules as they were in Valencia, this afternoon a unanimous agreement was reached. So from Germany onwards teams can go back to what they were doing before, only they will not be allowed to change engine maps between qualifying and the race.

Then at the end of the season, blown diffusers will be banned once and for all.

Ferrari boss Stefano Domenicali said, "I think that this thing was not really good for everyone. We need to draw a line and now look ahead, because otherwise where we are going? Even if I think I don't agree with the process, for the benefit of the sport we should have action."

Ferrari certainly benefitted today from the patched together agreement reached for this race only on Saturday. THis saw teams operating with between 10% and 20% of throttle open on lift off of the accelerator.

Although Ferrari has made progress with its car, Red Bull seem to have lost a couple of tenths of a second more this weekend. With the old arrangement back in place for the rest of the season, it is likely that this will put Red Bull in a better place than they were in this weekend, according to engineers I've spoken to this evening.
