The FIA's Charlie Whiting has sent the teams a further technical directive clarifying what can and cannot feature in pit to car radio conversations from the Singapore GP onwards.
The document confirms that a lot of technical information will also be banned from appearing on pit boards.
In some instances, regarding tire and brakes, the ban has been postponed until the Japanese GP.
In addition the FIA has specifically targeted “any message that appears to be coded.”
The FIA has confirmed that the restrictions “apply at all times the car is out of its garage during the Event,” which means all practice and qualifying sessions are included.
