The FIA wants to permanently eradicate blowing
The FIA had decided to limit the use of blowing by implementing new rules for 2012. However, it seems that development of engine mappings is still possible, and the governing body intends to put a definitive end to blowing by the start of the season.
The FIA has decided to ban blown diffusers for the 2012 season by adding several directives to the regulations, but this hasn’t stopped teams and engine manufacturers from developing ingenious and, for now, seemingly legal solutions. However, the FIA does not intend to stop there and reportedly plans to put an end to this, according to Autosport.
Blowing allows teams to channel exhaust gases onto a part of the car even when the driver is not accelerating, thus generating additional aerodynamic downforce – which is normally prohibited.
The FIA initially decided to limit engine mappings at the end of 2011, but this is not sufficient and it should go further by updating the standard electronic control unit (ECU) because, according to the British publication, F1 officials have been informed by an engine manufacturer that development possibilities for engine mappings remain possible despite the new rules.
A new version of the ECU software should therefore be implemented in all single-seaters by the first race of the season, the Australian Grand Prix, which will take place on March 18th.
