Hi Cuda, The video (and other media) states throttle response is "sharpened up" in track mode which led me to believe thottle body butterfly movement is increased in relation to accelerator pedal movement (ramped up) but monster is saying its ramped down so not sure. Pretty sure though there is not change to tune in relation to any stability/traction control inputs. Interesting the MRC has an input from torque vectoring though, wonder how that works. One MRC input for cornering would be via an accelerometer, we know there is at least one on board due to the g meter input, probably two. Maybe when taking a corner (in track mode) lateral accelerometer inputs to the MRC to stiffen up the outside dampers equally but when the torque vectoring criteria is met the rear outside is relaxed slightly to also aid turn in. Speculation on my behalf but I'd love to get my hands on a factory workshop manual, being the boring Alan I am I find the technical aspects ineresting.Hey Martin - If the butterfly opens more quickly, or just opens more, at any point of accelerator pedal position, then that is increasing the level of engine output available to the driver at that point. Hence, increasing engine performance...But, not overall. but It's the same power and tq at any point in the rev range, but, it may be more accessible, because the electronic management systems are relaxed. If that makes sense. So the driver can tap into the power and tq, with less, or maybe no electronic interference. I may be wrong, it's just what I am thinking is all.
