Arduino active exhaust system

Hi there

I am currently working on a project to have 2 arduinos and xbee shields connected to an ultra sonic ranger (throttle position sensor) as the input. this will open and close the valve according to the distance detected. i.e the closer to the sensor the more the valve opens.

This will also have three settings, Normal/sport and race these will adjust the speed that the valve opens.

Just wondering if there is a similar programme already out there.

Thanks in advance

Mike
