Not knowing much about the current Honda engines, I was surprised to hear that they rely on Lambda sensor feedback for monitoring the mixture. That starts to creep into familiar territory for me, so I'll ask the following:

Are the injection systems on the current Honda engine using a "fly by wire" throttle body with a throttle position sensor? If injector pulse and ignition timing is all digitally controlled by an ECU, it stands to reason that throttle operation is as well. Any information on the current Honda engines would be greatly appreciated, thanks.
