Our knock sensors are pretty decent. There are two main types of sensors. A decent one and a crappy version. Our sr's come with the better version. Mitsubishis on the other hand and I believe most hondas as well come with the crappy version knock sensor.
Do some research on knock sensors and how they function. It will go over the different types.
Our knock sensors are pretty sensitive but they do well and are a great tool for tuning if you have a standalone. The factory ecu makes corrections when knock is sensed as well but with a standalone you have a much more wide ability to see, data log, and make timing corrections when knock is sensed. Also our SR's make a lot of static noise mainly due to placement but not enought to really affect the way the motor runs.
As Vadim said in the factory ecu the ecu only reads knock to 4800 rpm or so. Whereas a standalone will read, can datalog, and make corrections throughout the entire powerband. So again much more wide range of use. Im using an AEM ems and it works great with our knock sensors.
