As far as drive-by-wire systems go, the RX-8's is pretty impressive. Unlike earlier versions of DBW, ours is virtually lagless. I was wondering if anyone had any data about the time delay in our electronic throttling processes under light, medium and heavy loading conditions.

 

Rasputin has done some analysis on throttle behaviour.. it may help to answer some of your questions.
