Venom Performance Control Module - PERFORMANCE CONTROL MODULE Improves horsepower by as much as 25% throughout 1000 to 5000-RPM power range! Enhances performance gains achieved from installation of an upgraded power chip Increases throttle response�reduces flat spots or delay time during sudden acceleration OBD II compatible Easy to install in 20 to 30 minutes with basic hand tools--no modifications to existing electronic components. Can be turned off to ensure smog certification. This add-on module connects to your car's sensors. It incorporates an 8-bit micro-controller that increases engine performance by constantly monitoring the sensors' output characteristics (more than 40 times/second) and modifying the input to your car's existing computer. Performance when you need it...automatically! During normal driving, the Venom 400(tm) is passive. It activates only when the micro-controller "senses" that the engine airflow and throttle position require more performance. When performance demands return to normal, the Venom 400(tm) returns to "sense only" mode. Red LED indicates when the module is activated. Can be turned off with the flip of a switch, restoring performance to original-equipment specifications. Normal fuel economy is maintained. Safe for car's electronics. Will not trigger car's emission safeguards. Works with automatic and manual transmissions. Applications:1998-2001 Honda Accord
