 - Includes utility to configure revburner tachometer
 - Can send data to any serial device. So far only tested with arduino. Includes sample arduino sketch for sim lights.
 - The support for haptic bass shakers is limited and needs the most work. So far the engine rev is a simple sine wave, which I find convincing. The gear shift event works but not convincing enough for me.
