Q&A - Charlie Whiting, FIA

Excerpts from Charlie Whiting's media briefing in Valencia ahead of the European Grand Prix
Engine map change restrictions

Simply put, what are teams now banned from doing under parc fermŽ conditions?

Charlie Whiting:
The teams are not allowed to make any changes with a computer that they plug in. The drivers are still allowed to change things from the steering wheel [however] the single ECU only supports fine adjustments from the steering wheel.

In very general terms, anything that can be done from the wheel is OK; anything they need to connect a computer for is not.

We are on the verge of issuing a note to the teams to give them a list of things that they can change when they connect their computers but that will be a very limited list.

What will happen if the weather conditions change between qualifying and the race?

Charlie Whiting:
We will allow certain changes to be made for ambient conditions. Normally, we only announce a change of climatic conditions if one [session] is dry and one is wet, but we have indicated to the teams that if there is a change in ambient temperature of more than 10¡C between qualifying and the race, we would allow them to compensate for that. But that's all.

What is the goal of implementing this change?

Charlie Whiting:
A team can't have a base map in the ECU that is only good for a few laps. If you want to use it, you have to use it for the whole race.

There isn't anything to prevent [a team] from exploiting the use of their exhaust gasses – providing those exhaust gasses are there for the genuine reason of engine combustion.

Will this affect every team equally, or will some suffer a greater penalty?

Charlie Whiting:
It is not for us to say whether or not one team will be penalised more than another. If depends how extreme they're going [with their previous map]. I've certainly seen evidence of maps from a number of teams that are Ôextremely' extreme. And it's not confined to one team.

Why do you want to see this stopped?

Charlie Whiting:
Because it's illegal.

How big an effect will this have on qualifying lap times?

Charlie Whiting:
It isn't something that we concern ourselves with and it's impossible for us to quantify it. However, during discussions I've heard that the most extreme maps may give you half a second a lap, but that would vary from car to car.

Blown diffusers:

Why will the off-throttle blown diffusers be banned from Silverstone onwards?

Charlie Whiting:
We know exhaust gasses have an influence on the aerodynamic performance of the car and we accept that. The point is that a design should not attempt to use the exhaust for a completely different reason [aerodynamics as a primary, rather than a secondary effect].

What are the new operating conditions with regard to throttle-opening and spark?

Charlie Whiting:
We only want to target this one specific issue – what we think is illegal use of maps for aero reasons. We don't want to influence the perfectly legitimate systems on the car – engine braking for example. We're happy for them to use that, but we want to be sure it isn't being abused.
