Oct.24 (GMM) The FIA is moving to clamp down even harder on the aerodynamic use of exhaust gases ahead of the 2012 season.

F1's governing body had already announced the end of the so-called 'blown diffuser' era by dictating the positioning of the exhausts and limiting the allowable off-throttle engine maps for 2012.

But Italy's Autosprint reports that, following fears the new rules could also have been exploited by teams, the FIA has "turned the screw" even tighter.

The Paris federation has reportedly said that the 2012 version of the software to electronically control the engine will be "even more limited" than was previously expected.

Williams' new chief engineer Mark Gillan is quoted as saying: "I don't think I've ever seen a year when there were no loopholes in the technical regulations.

"That is one of the most enjoyable aspects of our work -- to seek out areas in which the rules are vague and can be exploited."
