Land of the rising sun....
Fascinating and insightful interview Peter Windsor did with Scarbs on Ferrari's engine:

My simpletons take, Ferrari had contravened the spirit of the rules and were asked by the FIA to remove said advantage behind closed doors.
The audible whine we heard from the Ferrari (electrical?), second sensor and ice on the air inlet had given them a distinct advantage in terms of peak power but may have also been utilized as a quasi traction control system.
Will be great to see Honda out develop Ferrari in the engine compartment.
