FIA give explanation engine mapping modification

June.27 – FIA’s new rules active from British GP (July: 8-10), F1 teams will no longer be capable to make use of higher engine mapping set to reap lap time gains in qualifying. FIA technical delegate Charlie Whiting gives details, what the changes of the engine mapping modifications.

“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, but the single ECU (Electronic Control Unit) only supports fine adjustments from the steering wheel,” Whiting begins.

“In very general terms, anything that can be done from the wheel is okay; 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.

“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 them from exploiting the use of their exhaust gasses – providing those exhaust gasses are there for the genuine reason of engine combustion.”

Whiting answer for, one of the important Question: If all teams will be equally affected by the changes?

“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. I’ve certainly seen evidence of maps from a number of teams that are extreme.

Charlie Whiting also explained why the ban will be compulsory for the British GP onwards; with Red Bull Team Principal Christian Horner having questioned why 2012 would not have been a more suitable option.

“Our argument is that there is a strong case to suggest they (blown diffusers) are illegal,” Whiting continued. “Ultimately, the stewards will decide.”
