Hi group, I'm running a 2011 335ix with sport package, oil cooler, 18" wheels, and code 840 speed delimiter. Does anyone know exactly how the speed delimiter works ? I know it does allow the speed to go past the "limited" 130 mph or so, supposedly up to 150 ? I'm curious as to how it does this ? Anyone had the opportunity to push there 335 with sport package past 130 to see what the effect of the "high speed synchronization" feature actually does ? Any source explaining the technology ? Thanks, Tony
