Just a small video one of our customers in Europe took. As well a launch control and flatshift, we are now doing a very fast reacting spark cut RPM limiter. As standard, there is a throttle closure, so if you hit this limiter it can take a while for the engine to spool up again. The spark cut allows much better control, especially on big power FWD cars.
