The rear window louvers that were original equipment on some 60s and 70s muscle cars were first and foremost, styling statements. They were part of an appearance package that was created to set these cars apart from lower performance plain Jane versions and were usually combined with features like stripes, spoilers and vinyl roofs. In addition, while they did not improve the aerodynamics of the vehicle, they created a dead air zone that helped traction by reducing rear lift. Some pony...

A radar detector is an electronic device that has been used by motorists, for decades, to detect if their speed is being monitored by police using a radar gun. It gave a driver sufficient warning to reduce his speed to avoid being ticketed for speeding. In a general sense, only emitting technologies, like Doppler radar, or LIDAR (pulsed laser light) can be detected. Visual speed estimating techniques, like ANPR or VASCAR cannot be detected in daytime. There are also no reports that piezo...

An engine control unit (ECU), also commonly called an engine control module (ECM), is the brain of your car. It is the main reason that we are now in the second era of muscle cars, despite restricting emission regulations. The ECU controls a series of actuators on an internal combustion engine to ensure optimal engine performance. It does this by reading values from a multitude of sensors within the engine bay, interpreting the data using multidimensional performance maps (called look-up...
