P210 - but that's not a function of direct injection
Direct injection primarily allows better atomisation at lower intake air velocity - ie part throttle.
Once you the throttle is open a decent amount, it is usually more efficient to inject the fuel further upstream so it has time to mix properly with the air - many race cars have a second bank of injectors that they only use at high rpm specifically for this reason.
There are potentially lots of benefits from moving away from clockwork engines - variable ignition timing combined with well designed injection setup could make running LOP or to any other desired condition utterly foolproof.
Look at developments like ion-sensing ignition too....
